What's in this Duolingo clone
A language-learning product needs a coherent curriculum and useful feedback, not just points and a streak counter. Pick one learner level and a small set of practical situations. Build a lesson that teaches, checks recall and revisits mistakes. The quality of the examples and explanations is part of the product, not filler to add after the interface.
Features to build
A proposed scope for your own app, not a list of features in a prebuilt project.
| Feature | What to implement |
|---|---|
| Learning path | Organize lessons by skill and prerequisite, with a clear explanation of what the learner will practice next. |
| Exercises | Mix recognition and recall tasks, keeping instructions concise and allowing learners to understand why an answer was wrong. |
| Audio practice | Provide replay controls and transcripts for approved recordings, with a usable alternative when sound is unavailable. |
| Review queue | Bring back items the learner struggled with rather than simply repeating the entire most recent lesson. |
| Progress | Track completed skills and study sessions, distinguishing demonstrated understanding from time spent in the app. |
| Study reminders | Let learners choose a schedule and pause reminders without turning a missed day into a punitive experience. |

Your starting prompt
Build an original app for this audience and workflow on the platform I select in Superapp: iPhone or web.
The hard parts
Content modeling determines whether lessons can grow without becoming inconsistent. Store accepted answers, explanations and audio references together, and let qualified reviewers approve revisions. Free-text answers may have several valid forms; a strict string comparison can teach the wrong lesson. Speech scoring is a separate capability that needs testing across accents and recording conditions. Do not imply that a generated score proves fluency or that a streak measures language proficiency.
Take it from prototype to real app
Observe a beginner completing a lesson without assistance. Include an ambiguous answer, unavailable audio and an interrupted session. Check that review practice returns the right items and that progress survives a restart. Have a qualified speaker review explanations before inviting learners. Start with a small curriculum that can be maintained well. Add leagues, rewards or an AI tutor only after the teaching loop produces useful feedback and learners can explain what they have learned.
Three niche variations
Travel phrases
Build a beginner phrase-learning app for travelers visiting Portugal. Organize lessons around transport, ordering food and asking directions. Include approved audio, short recall exercises and explanations for accepted variants. Let learners save useful phrases for review. Avoid claiming fluency from completing a small travel course.
Heritage language
Create a family heritage-language practice app with short listening lessons and everyday conversation prompts. Support multiple accepted expressions and notes from a qualified speaker. Keep pronunciation examples attributed and reviewable. Let learners practice privately without public leaderboards, and show progress by skill rather than a single competitive score.
Workplace vocabulary
Make a language practice app for hospitality staff. Teach guest greetings, directions and common service requests through short scenarios. Provide audio replay, useful feedback and a review queue for missed phrases. Let a language reviewer approve every lesson. Keep training examples separate from any formal workplace certification.
Duolingo clone app: what it costs
Budget separately for development and operation. The agency figure below describes its stated scope; a Superapp subscription buys a creation tool, not the same managed delivery service.

Publish for iPhone or the web
Choose your platform in Superapp before starting. For a web app, test the published site in desktop and mobile browsers. For an iPhone app, test on devices and prepare an App Store submission.
Duolingo clone for iPhone: will Apple approve it?
Approval is not guaranteed. Apple requires originality; review guideline 4.1.
The icon identifies the reference app. It is not branding for your project or a claim of affiliation. Choose an original name, artwork and purpose, then test the complete release with the content and services your users will actually encounter.
Quizlet clones
A Quizlet-inspired variation emphasizes study sets and recall rather than a sequenced language curriculum. Let learners create or import approved material, then keep answer explanations and review scheduling attached to each learning item.
