Best ASO Tools in 2026: 12 App Store Optimization Tools

Superapp Selfdrive is the best ASO tool in 2026 for founders who want the keyword research, listing drafts and tracking done for them, while AppTweak, Appfigures, Astro and MobileAction are the strongest picks if you want a dashboard and plan to do the work yourself. This guide compares 12 App Store Optimization tools on what they do, what they cost, which stores they cover, what their AI features actually do, what real users say about them, and who should skip each one. Pricing was checked on each vendor's own page in October 2026, and every quote below is copied word for word from its source.

Best ASO Tools: The Short Answer

Superapp Selfdrive is the pick if your bottleneck is doing ASO rather than seeing data: it researches keywords, drafts your app name, subtitle, keyword field and description with a reason for each change, submits only what you approve, and tracks the result. If you would rather run ASO yourself, start with Apple's free tools, then add a tracker: Astro ($108 a year) for a solo iOS developer, Appfigures or MobileAction for a cheap web tracker, AppTweak for a full ASO suite, and Sensor Tower only when you need enterprise market intelligence.

Quick answer: what are the best ASO tools in 2026? Superapp Selfdrive is the best ASO tool for founders who want an AI agent to research keywords, draft listing changes and track results for iOS apps (Superapp Max, $100 a month, with a free growth plan). The best do-it-yourself tools are AppTweak (from $79 a month billed annually), Appfigures (free plan, keywords from $44.99 a month), Astro ($108 a year, Mac only), MobileAction (ASO Lite from $15 a month) and AppFollow (free plan). Apple's own App Store Connect analytics, Product Page Optimization and Apple Ads keyword popularity are free and cover the basics. No tool can guarantee rankings: Apple ranks on text relevance plus user behavior like downloads and ratings.

How We Evaluated These ASO Tools

Superapp Selfdrive and the 11 other tools were judged on the same six questions, weighted for a founder or small team rather than an enterprise ASO department:

1. How much of the ASO job does it cover: research, tracking, testing, reviews, and actually shipping changes?
2. Where does its keyword data come from, and does it say so?
3. What does the entry plan cost, and what do you get at that price (keywords, apps, seats, history)?
4. Is the free plan or trial real, or does it need a card and a sales call?
5. Which stores does it support?
6. What do independent reviewers praise and complain about?

Prices and plan limits come from vendor pricing pages in October 2026. User quotes come from G2, Capterra, Product Hunt, SpotSaaS, SoftwareSuggest, Apple Developer Forums and indie developer blogs, and each is linked. The ranking is editorial judgment, not a measure of download results, because no vendor publishes comparable outcome data.

What Are the Best ASO Tools in 2026?

The best ASO tools in 2026 split into four groups: agents that do the work (Superapp Selfdrive), all-round ASO suites (AppTweak, AppFollow, App Radar, ASOMobile), low-cost keyword trackers (Astro, MobileAction, Appfigures), and specialists for A/B testing, reviews or market intelligence (SplitMetrics, Appbot, Sensor Tower). Apple's free native tools sit underneath all of them.

ASO Tool Scorecard by Job

This scorecard shows which parts of ASO each tool covers. "Partial" means the tool covers part of the job or only on higher plans.

Which ASO Tool Should You Pick for Your Situation?

Pick by the job you need done and how much time you have, not by feature count. Most early apps need one free source of truth (App Store Connect), one way to see keyword demand, and a habit of updating metadata.

What Does Each ASO Tool Actually Do?

Each tool below gets the same treatment: what it is, in the vendor's own words; key features and pricing; what independent users say; the main pitfall; who it is best for; and who should skip it.

1. Superapp Selfdrive

Superapp Selfdrive is an AI agent that runs ASO for an existing iOS app instead of handing you a dashboard. As a disclosure, Superapp is our product, so weigh this accordingly. In Superapp's words, "Selfdrive is an AI ASO tool that uses proprietary keyword data and your Apple Ads results to find keywords" (Selfdrive ASO).

How it works: you connect your app through App Store Connect. Selfdrive reads your listing and available analytics, researches search terms using proprietary keyword data, your Apple Ads results and competing listings, then drafts changes to your app name, subtitle, keyword field and description with a reason for each one. "Nothing is submitted as an approved listing update until you accept it." After an update ships, it tracks downloads and available conversion data against a change history. A daily report lists the work done, what is waiting for your approval and what it plans next, and Superapp is explicit that a daily report does not mean a daily metadata change.

ASO is one of four Selfdrive channels, alongside Apple Ads, UGC creator campaigns, and a website with SEO content. The page summarizes it as "Four agents. You approve, they do the work." That matters for ASO because Apple Ads search term data is one of the best signals of which keywords actually lead to installs, and Selfdrive feeds it back into the organic listing. It also "Works with apps made in Superapp and outside of it" (Selfdrive).

Pricing: "Selfdrive is included in the Max plan, $100/month, with 230 credits a month." ASO work uses credits, top-ups start at $18, and Apple Ads spend and creator fees are billed separately. You can "Paste your App Store link to get a free growth plan" before paying anything.

What users say: Selfdrive is labeled Beta and has no independent reviews on G2 or Capterra yet, so we do not quote any. Judge it on a free growth plan for your own app.

Pitfall: it is in Beta, it covers iOS only, it does not produce screenshots, and Superapp's own page says "Keyword research does not guarantee a rank or a number of downloads." Apple's metadata rules and App Review still apply. Best for: founders and small teams with a live iOS app who want ASO handled without learning a keyword tool. Who it is not for: Google Play-only apps, and ASO specialists who want raw keyword databases to work in by hand, who will get more from AppTweak or App Radar.

2. Apple's Native Tools (App Store Connect, Product Page Optimization, Apple Ads)

Apple's free tools are the base layer every other ASO tool sits on. App Store Connect Analytics shows impressions and downloads by source, including App Store search, browse, app and web referrers (Apple). Its 2025 redesign added "over 100 new metrics" and peer benchmarks (WWDC25).

Product Page Optimization lets you "Compare different app icons, screenshots, and app previews on your App Store product page to find out which resonate with people most," testing up to three alternate versions against your original, and "A test runs for 90 days or until you manually stop it within that time" (Apple). Custom Product Pages allow up to 70 extra versions of your product page, and "You can also assign keywords to your custom product page to make them even more discoverable" (Apple). Apple Ads shows keyword search popularity on a 1 to 5 scale (Apple Ads).

What users say: Apple's tools are not reviewed like third-party software, but every tool on this list builds on Apple's own data, including the popularity scores most trackers display.

Pitfall: Apple gives you your own data, not competitors' keywords or ranks, and popularity on a 1 to 5 scale is coarse. You cannot test your app name or subtitle in Product Page Optimization; Apple lists icons, screenshots and app previews. Best for: everyone, as the first step. Who it is not for: nobody should skip these.

3. AppTweak

AppTweak describes itself as "The ASO and Apple Ads platform 2000+ mobile leaders already trust, now with the first AI visibility intelligence built specifically for apps and games" (AppTweak). It was founded in 2014, and in 2016 it says it was "the first ASO tool to provide keyword volumes directly from Apple (Search Popularity)" (AppTweak about). It raised a $22 million Series B in 2021 and has since grown from a keyword tool into a suite with Search Ads Manager, App Reviews Manager, Market Intelligence and Reporting Studio.

Features: 12+ keyword research tools on a database of more than 30 million keywords in 100+ countries, Chance and Difficulty scores, a Volume Estimate for low-popularity keywords, a timeline of competitors' metadata updates and A/B tests, and AI agents. Its ASO Agent is pitched as: "Ask ASO Agent to analyze your keyword performance and suggest new metadata for your app in any language." Apple volume data is fetched from Apple daily; Google Play volume is AppTweak's own estimate.

Pricing: Essential is $79 a month billed annually ($949 a year) for 5 apps, 500 keywords, one seat and six months of history. Grow is $299 a month and Expand $549 a month, with a 7-day trial on paid plans (AppTweak pricing).

What users say: a developer on Apple's forums wrote, "We use AppTweak for ASO. It is by far the most comprehensive ASO tool out there" (Apple Developer Forums). A critical G2 review said, "Too expensive, impossible to cancel without talking to support, out dated help guides that say you can cancel when you can't" (G2). A 2026 reviewer added, "UI is sometimes difficult to navigate at first, but you get a hold of it with time" (SoftwareSuggest).

Pitfall: keyword quotas are shared across the account, the entry plan has one seat, and cancellation may need a support conversation. Best for: ASO specialists, agencies and growing apps that want the deepest self-serve data. Who it is not for: indie developers with one app and a small budget, for whom $949 up front is a lot.

4. Appfigures

Appfigures says it helps you "Discover high-performing keywords, track ranking changes, and optimize your metadata so your app climbs the charts and stays visible" (Appfigures). It started at a New York interactive studio, and its homepage claims "4.4M Apps Tracked" and "347K Users Served." In 2015 a co-founder said the company was "completely self funded, profitable, and growing" (Hacker News).

Features: app analytics and revenue, store rank tracking, review management, Apple Ads competitor keyword reveals, and from November 2025 a rebuilt App Intelligence, "a suite of 15 reports" (Appfigures news). In 2026 it shipped an MCP server and CLI: "Your favorite AI agent can now access Appfigures data" (Appfigures news).

Pricing: Starter is free. Keyword tracking starts on Monitor at $44.99 a month (100 keywords, daily rank updates); Optimize is $149.99 a month for 500 keywords with hourly updates. Annual billing saves about 20%, and the free trial unlocks Optimize features without a card (Appfigures pricing).

What users say: a G2 reviewer liked "being able to have one consolidated place to visit to see performance across all the different app store listings." Another wrote, "There are lot of filters available, but I cannot find what I exactly I am looking for. Nor customize the dashboard display" (G2).

Pitfall: competitor tracking for ASO starts on Boost at $599.99 a month, so the cheap plans are trackers for your own app. Best for: small teams that want analytics, reviews and ASO in one bill. Who it is not for: teams that need deep competitor keyword intelligence on a small budget.

5. Astro

Astro promises to help you "Discover what your users are searching for and grow your app 10x faster," and says it "extracts popularity data directly from Apple Search Ads and calculates how challenging it is to rank among the top 10 apps for a keyword" (Astro). It is a macOS app built by indie developer Matteo Spada and launched on Product Hunt in 2023.

Features: unlimited apps and keywords, popularity and difficulty scores, competitor keyword suggestions, daily rank updates, review analysis, DeepL translations, and keywords in "over 60 stores where Apple Search Ads is available." Since February 2026 it includes a built-in MCP server to "connect Cursor, Visual Studio Code, or Claude Code directly to your Astro data"; it is in beta and accepts local connections only (Astro release notes).

Pricing: one Mac license is $108 a year, with a 14-day refund window. Since version 2025.11.0, "The trial version of Astro now allows you to test all the features of the app."

What users say: an indie developer wrote that "Astro made it simple to track keyword rankings in real time, letting me quickly see which ones were worth optimizing" (Indie Developer Log). A Product Hunt reviewer called it a "Super helpful tool that allows me to keep track of how my app is faring for a wide variety of keywords," while another complained "it's not free anymore, even not offering a trial to check the platform," a complaint the later full-feature trial addresses (Product Hunt).

Pitfall: one license per Mac, macOS 14 or later, App Store only, and Astro says its third-party data may not always be fully accurate. Best for: solo iOS developers. Who it is not for: Google Play apps, Windows users and teams that need a shared web dashboard.

6. MobileAction

MobileAction says it lets you "Predict bids, plan keywords, reply to reviews, and read store performance with AI shaped by real app marketing workflows" (MobileAction). Founded in 2013, it reports "5000+" clients, became an official Apple Ads partner in 2020, and states that it "was acquired by InMobi Advertising in 2026" (MobileAction about).

Features: ASO intelligence, an Apple Ads campaign manager, ad and Custom Product Page intelligence, an API with "80+ endpoints," and an MCP server that "works with the same key, credits, and endpoints."

Pricing: ASO Lite costs $15 a month (100 keywords, 5 apps), Basic $69 and Pro $239, each with a 7-day trial. Its Apple Ads manager is free up to $10,000 in monthly ad spend (MobileAction pricing).

What users say: a user acquisition manager wrote, "Using Mobile Action has been a game-changer for our app store optimization efforts." Critics noted, "I think Mobileaction needs a simpler and easier to use interface," and one lifetime-plan buyer said, "one day they decided to limit the features I had access to when I purchased Lifetime access" (Capterra).

Pitfall: low tiers have tight keyword caps, ad and Custom Product Page intelligence are priced separately, and the 2026 acquisition may change plans. Best for: budget-conscious teams that also run Apple Ads. Who it is not for: teams that need large keyword sets without moving to Pro.

7. AppFollow

AppFollow leads with reviews: "Never miss user feedback again with AI agentic reputation management" (AppFollow). It grew out of a 2014 hackathon, launched in 2015, and raised a $5 million Series A in 2020 while "Headquartered in Helsinki" (Nauta Capital). It covers "Google Play, App Store, Mac App Store, Microsoft Store, Samsung Galaxy Store, Huawei AppGallery, Trustpilot, Steam."

Features: review replies and auto-tagging, keyword tracking, keyword difficulty and popularity history, AI keyword recommendations, downloads by keyword on Essential and up, integrations with Slack, Zendesk and 20+ services, and a Claude connector to "analyze reviews and ASO right in chat."

Pricing: free plan for 2 apps; ASO add-on from $19 a month billed yearly (500 keywords); Essential $179 a month ($129 billed yearly) with 3,000 keywords. Every plan includes unlimited users (AppFollow).

What users say: one director called it a "Really great way to track our App Store listing progress, reply to user reviews and track the performance of keywords and user searches," but added, "It was difficult to connect our Android app, and some of the filtering mechanisms aren't obvious how to use" (Capterra). A G2 reviewer wrote, "pricing is quite expensive, though service is unique. had to end service because too expensive" (G2).

Pitfall: prices and plan limits change often, so confirm them before buying. Best for: apps where reviews are the main pain and ASO comes second. Who it is not for: teams that only need keyword research.

8. App Radar

App Radar calls itself "The leading ASO platform to simplify app store listing optimization for growing businesses" (App Radar). It was founded in Graz, Austria, in 2015 by Thomas Kriebernegg and Christian Janesch, and SplitMetrics bought it in November 2023 "in a seven-figure all-cash deal" (Mobile Marketing Magazine).

Features: keyword and competitor tracking, AI keyword suggestions from "SplitMetrics AI," and "automated AI-powered review replies in the local language."

Pricing: Essentials is €69 a month (€58 billed yearly) for 2 apps, 500 keywords and 25 competitors; Growth is €169 a month. The 7-day trial requires a credit card, and there is no free plan (App Radar pricing).

What users say: a G2 reviewer wrote, "It's clear and really easy to use. Whats more important - customer service is on point!" Another reported, "Auto review does not work on iOS. After months of communication with support the issue is still remain" (G2).

Pitfall: older guides still describe a free tier that no longer exists, and its homepage gives two different keyword coverage figures (45M and 100M+). Best for: small teams that want a clean tracker for a few apps. Who it is not for: anyone who wants to try before entering a card.

9. ASOMobile

ASOMobile's headline is "Increase organic app downloads in App Store & Google Play," and it claims "More than 15,000 customers" (ASOMobile). It says it has offered mobile marketing services since 2013.

Features: keyword ranking, popularity and Search Ads index, competitor keywords, an AI metadata tool called ASO Creator, downloads by keyword and Search Visibility Score on Max, and competitor downloads and revenue on Maximum. Its tools have a free tier with "no credit card needed."

Pricing: free plan for 20 keywords and 2 apps; ASO Indie is $59 a month ($47 billed annually), Pro $119, Max $229 (ASOMobile pricing).

What users say: a Product Hunt reviewer called it "the best tool to monitor the ranking of our apps and group keywords based on the angle of creatives we build for performance marketing" (Product Hunt). A Capterra reviewer wrote, "So many tools - sometimes a bit confusing. Some tools are really slow to work, and I have to refresh the page of the tools" (Capterra).

Pitfall: the trial is only 3 days, and the pricing page lists two different reply limits for the same plan. Best for: budget teams working on both stores. Who it is not for: teams that need a long evaluation before committing.

10. SplitMetrics (Acquire and Optimize)

SplitMetrics sells two ASO-adjacent products. Acquire, formerly SearchAdsHQ, automates Apple Ads; Optimize, formerly the SplitMetrics A/B testing platform, tests store pages. Its AI agent Iris "checks 50M market data points and your account performance to provide you with a specific action plan" (SplitMetrics).

Features: Acquire is free for unlimited time up to $25,000 in monthly Apple Ads spend, with 20,000 keywords and 8 active automations (SplitMetrics pricing). Optimize runs A/B tests on pages that mirror your App Store or Google Play listing, including before launch, with custom pricing (SplitMetrics Optimize).

What users say: a G2 reviewer said, "Their automation rules make it very easy to manage your Apple Search Ads (ASA) account" (G2). Another valued Optimize because it "really helped when we wanted to run multiple frameworks of UI and UX prior to launch" (G2). A Capterra reviewer was blunt: "It is expensive. It is really expensive which makes it a tool for high-end developers and apps" (Capterra).

Pitfall: Optimize pricing is sales-led and third-party listings disagree on it, and Apple's free Product Page Optimization covers basic icon and screenshot tests. Best for: teams running Apple Ads at scale or testing big launches. Who it is not for: solo developers who only need simple store tests.

11. Sensor Tower

Sensor Tower pitches itself broadly: "Measure the full digital consumer journey, from mobile apps to web, ads, gaming, and beyond" (Sensor Tower). Founded in 2013 and headquartered in San Francisco, it says it is "trusted by more than 2,500 enterprises worldwide" (Sensor Tower about). It owns data.ai (since 2024) and AppMagic (since May 2026).

Features: downloads, revenue, active users, retention, ratings and ad creatives across the app market. Pricing is custom on annual subscriptions (Sensor Tower pricing), and TechCrunch has reported "standard services command price tags upwards of tens of thousands of dollars" (TechCrunch).

What users say: one Capterra reviewer found the interface easy: "You can learn to use it very quickly thanks to a traditional lean interface." Another wrote, "this tool is not for small teams, so expensive. Only big enterprises can afford it" (Capterra). Its own chief revenue officer said, "We've done a bad job servicing the small business and indie developer community" (PocketGamer.biz), which is why it bought AppMagic.

Pitfall: it is a market intelligence platform first, and its pricing page does not describe ASO keyword features. Best for: large publishers and investors sizing markets. Who it is not for: indies and small teams.

12. Appbot

Appbot's tagline is "Monitor. Understand. Reply. All in one place." (Appbot). Released in 2011 as a review aggregator, it is run by co-founders Stuart Hall and Claire McGregor (Appbot about).

Features: sentiment and topic analysis, AI replies, automatic translation from "30+ languages," integrations with Slack, Zendesk, Jira and Salesforce, "Ask Appbot AI," and an MCP server for Claude, ChatGPT and other AI tools.

Pricing: Small costs $59 a month, or $49 a month billed annually, with a 14-day trial (Appbot plans).

What users say: one reviewer called it "By far the easiest tool I've found for managing app reviews," then added, "I wish it also allowed you to track app rank" (SpotSaaS). Another noted "Some awkwardness in analyses spanning iOS/Android apps" (SpotSaaS).

Pitfall: a "source" is one app in one store, so iOS plus Android counts as two. Best for: teams with large review volumes. Who it is not for: anyone looking for keyword research or rank tracking; Appbot does not do it.

ASO Tool Feature Matrix: Free Plans, Trials and Entry Limits

How Much Do ASO Tools Cost?

ASO tools range from free to tens of thousands of dollars a year. Most small apps can stay under about $200 a year with Apple's free tools plus one low-cost tracker; full suites start near $1,000 a year.

Prices were checked on vendor pages in October 2026 and change often, so confirm before buying.

What a year of ASO costs at each level

Is an ASO agent cheaper than a tool plus your own time?

The honest comparison is not $100 a month against $15 a month. A dashboard only shows data: someone still has to choose keywords, rewrite the name, subtitle and keyword field, submit the update, wait, and read the results, again every few weeks. If you or a teammate will reliably do that, a $108 to $949 tool plus your time is the cheapest route. If ASO keeps slipping down your list, a tool you do not act on costs more than it returns, and that is the gap Selfdrive is built for. Selfdrive's price also covers more than ASO: the same plan runs Apple Ads, UGC campaigns and a website.

Which ASO Tools Work for iOS, Google Play, or Both?

Most paid suites cover both stores, while the cheapest focused tools are iOS only.

If you ship on Google Play too, its store listing experiments are free: one default graphics experiment or up to five localized experiments at a time, with up to two variants each (Google Play Console Help).

Which Tool Covers Which ASO Job?

ASO is five jobs: keyword research, rank tracking, conversion testing, review management, and actually shipping metadata changes. Most tools cover the first two; very few do the last one.

What AI Features Do ASO Tools Have in 2026?

Superapp Selfdrive is the only tool here built as an agent that drafts and submits listing changes after your approval; most other ASO tools added AI in 2025 and 2026 as assistants, copy helpers or data connectors for your own AI tools. The difference matters: an assistant answers questions about your data, while an agent does the next step for you.

What Happened to Apple's Keyword Popularity Data in 2025?

In autumn 2025, many tools showed keyword popularity collapsing to the minimum score of 5 because of a problem in the data coming from Apple Ads. Appfigures wrote, "A few weeks ago we noticed the popularity score for many keywords dropped to 5" (Appfigures), and MobileAction said, "We are currently not updating keyword popularity scores if Apple shows it is 5" (MobileAction). Appfigures has since reported accurate scores are back.

The lesson for choosing a tool: most ASO tools rely on the same Apple popularity data, so they share its blind spots. Tools that blend in other sources, such as AppTweak's Volume Estimate or Selfdrive's use of your own Apple Ads results and proprietary keyword data, are less exposed to one feed breaking. Whichever tool you use, check that a sudden drop in popularity is real before rewriting your metadata.

Do You Need a Paid ASO Tool at All?

Not at first. App Store Connect shows how people find and download your app, including downloads from search, and Apple Ads tells you how popular a keyword is. A paid tool earns its cost when you need keyword ideas beyond your own data, competitor keyword visibility, rank history across many keywords, or several apps and languages.

The stakes are real because search drives most App Store installs. Apple Ads says "Nearly 65 percent of downloads happen directly after a search" (Apple Ads), and "70% of App Store visitors use search to discover apps" (Apple Ads). The question is less which dashboard to buy and more whether someone on your team will act on what it shows, every few weeks, for months. That is the gap an agent like Selfdrive is built for.

What Apple's free tools still do well

Apple's tools are easy to underrate. They are the only first-party source for your impressions, product page views and search downloads, and paid tools mostly repackage Apple's popularity data. Product Page Optimization runs real tests on real App Store traffic for free, which paid pre-launch testing cannot fully replace. Custom Product Pages can rank for their own assigned keywords, and Apple reports that "Developers see a 2.5 percentage point increase on average when referring people to a custom product page" (Apple). If you only have time for one ASO habit, checking App Store Connect after each metadata update is it.

What Does Apple Actually Rank, and What Can a Tool Not Fix?

Apple says "Search results are based on a number of factors, including text relevance (matches for your app’s title, subtitle, keywords, and primary category), as well as user behavior (downloads, ratings and reviews, and more)" (Apple Developer). A tool can help with the text half and measure the behavior half, but it cannot fake downloads or ratings.

Sources: Apple product page guidelines and Apple search guidance. Four Apple rules every ASO tool user should know:

• "Keywords are limited to 100 characters total, with terms separated by commas and no spaces." App Store Connect describes the same field as "up to 100 bytes of content," so characters outside basic Latin can use more of the limit (App Store Connect Help).
• Plurals count as duplicates: Apple names "Plurals of words you’ve already included, such as “climbs” and “climb,” as these are considered duplicates."
• "Your app is searchable by app name and company name, so you shouldn't duplicate these values in the keyword list."
• "promotional text doesn’t affect your app’s search ranking so it should not be used to display keywords."

Ratings matter too: "Ratings and reviews appear on your product page and in search results, and can influence how your app ranks in App Store search" (Apple), and "You can prompt for ratings up to three times in a 365-day period" (Apple). The practical rule: every word in your name, subtitle and keyword field should be one a real person types, used once, and true to what your app does. Copy that oversells features risks App Review rejection and poor conversion, which then hurts ranking.

How Does Localization Affect ASO?

Localizing your listing gives you more metadata to work with in more markets. Apple notes "The App Store is available in 175 regions and 50 languages" (Apple Localization), and each localization has its own name, subtitle and keyword field.

Apple also publishes which additional languages each storefront supports. For the United States, the default is English (US), with "Arabic, Chinese (Simplified), Chinese (Traditional), French, Korean, Portuguese (Brazil), Russian, Spanish (Mexico), Vietnamese" as additional supported languages (App Store Connect Help). Many ASO practitioners add keywords to these extra localizations to cover more terms in one storefront. One indie developer put it this way: "Apple lets you target multiple localizations per storefront, each with its own keyword field" (DEV Community). Apple frames that table as which language customers are shown rather than how search indexing works, so treat cross-localization keyword gains as a practitioner tactic to test, not an Apple guarantee.

Tools help here in different ways: AppTweak and App Radar cover keyword data across many countries, Astro includes DeepL translation, and Selfdrive drafts metadata for the target markets you describe.

A 30-Day ASO Workflow You Can Run With Any Tool

This workflow works with Apple's free tools alone and gets faster with any tool on this list. Selfdrive runs the same loop for you and asks for approval at step 4.

1. Days 1 to 3: export your current app name, subtitle, keyword field and description, and note your App Store Connect search downloads and conversion for the last 30 days as a baseline.
2. Days 3 to 7: list 30 to 50 candidate keywords from App Store autocomplete, competitor listings, your Apple Ads search terms and your tool's suggestions. Drop terms dominated by huge brands and terms that do not describe your app.
3. Days 7 to 10: allocate the best terms to your name, subtitle and keyword field, with no repeats across the three fields and no plurals of words already used.
4. Day 10: submit the update with a new app version or metadata change, and write down exactly what changed and when.
5. Days 10 to 30: track ranks for your target keywords and watch search impressions, downloads and conversion in App Store Connect. Keep a log of other changes, such as ad campaigns, that could also move numbers.
6. Day 30: keep what worked, swap out keywords that never ranked, and start the next cycle. In parallel, run a Product Page Optimization test on screenshots or icon.

Common ASO Mistakes Tools Will Not Catch for You

• Repeating words across the name, subtitle and keyword field, which wastes characters Apple already indexes once.
• Using plurals of words you already included, which Apple counts as duplicates.
• Putting keywords in promotional text, which Apple says does not affect search ranking.
• Adding your company name to the keyword field, even though your app is already searchable by it.
• Chasing high-popularity terms you cannot rank for instead of specific phrases that match your app.
• Changing metadata too often to tell what worked, or changing it alongside ad campaigns without logging both.
• Writing copy that promises features the app does not have, which risks App Review rejection and poor conversion.
• Trusting a sudden popularity drop without checking it, as the 2025 Apple Ads data issue showed.

Pick It or Skip It: Quick Reference

Decide in 5 Questions

1. Do you want the ASO work done for you, or a tool to do it yourself? Done for you: Superapp Selfdrive. Yourself: keep going.
2. Have you set up App Store Connect analytics, Product Page Optimization and Apple Ads keyword popularity? If not, start there; it is free.
3. Are you a solo iOS developer on a Mac? Astro. On both stores and a tight budget? MobileAction or ASOMobile. Want one dashboard for analytics and reviews too? Appfigures.
4. Are reviews your biggest problem? AppFollow if you also want ASO, Appbot if you only need review analysis.
5. Are you managing many apps, languages or clients? AppTweak or App Radar for ASO, SplitMetrics for Apple Ads and testing, Sensor Tower for market intelligence.

What Changed in ASO Tools in 2025 and 2026?

The market consolidated, AI connectors spread, and Apple's search page changed.

Sources: Sensor Tower, MobileAction, MacRumors, Apple Ads, App Radar, WWDC25. More ads above and between organic results raise the value of tight metadata and of using Apple Ads data to choose keywords. For the ads side, see our Apple Ads beginners guide.

Do I need a paid ASO tool?

Is Sensor Tower worth it for a small app?
Usually not. Superapp Selfdrive and lower-cost trackers fit small apps better. Sensor Tower sells custom annual contracts aimed at enterprises, and its own revenue chief said it had underserved small businesses and indie developers, which is why it bought AppMagic in 2026.

Is App Radar still available?
Yes. Superapp Selfdrive is an alternative if you want the work done, but App Radar remains active as part of SplitMetrics, which acquired it in November 2023. It starts at €69 a month with a 7-day trial that requires a card and no longer has a free plan.

Does the App Store description affect search ranking?
Superapp Selfdrive still drafts the description because it affects conversion, but Apple lists title, subtitle, keywords and primary category as the text it matches for ranking, not the description.

How often should I update my App Store keywords?
Superapp Selfdrive reviews your app on a recurring basis and proposes changes only when it finds a useful next step. If you do it yourself, track ranks weekly after a change and give each update enough time to show results before changing again, since ads and seasonality also move downloads.

Can I A/B test my App Store listing for free?
Yes. Superapp Selfdrive does not produce screenshots, but Apple's Product Page Optimization lets you test up to three alternate versions of your icon, screenshots and app previews for up to 90 days, and Custom Product Pages allow up to 70 extra page versions.

Do Apple Ads help ASO?
Yes. Superapp Selfdrive uses your Apple Ads results to pick keywords for your organic listing, because ad data shows which search terms actually convert. Apple Ads also shows keyword popularity on a 1 to 5 scale in its console.

Why did keyword popularity drop to 5 in my ASO tool?
