Teachers, tutors and diaspora communities build language apps because the big ones don’t cover their pair or their dialect — Hausa for English speakers, Bengali for kids abroad, medical English for nurses. The content is what you already teach; App Builder Agent turns it into lessons, flashcards and quizzes with streaks and audio.
This guide covers the lesson structure, spaced repetition, audio, and how to paste your own word lists so the app is yours from the first minute.
What a language app needs
Learning apps live or die on daily use. Build the loop:
- Lessons in small units — 10–15 words or phrases per lesson, grouped by topic (greetings, market, transport).
- Flashcards with spaced repetition — Show, flip, rate (again/hard/good/easy); the app schedules reviews.
- Audio — Pronunciation per item — your recordings, or device text-to-speech to start.
- Quizzes — Multiple choice, type the word, match pairs, listen and pick.
- Streaks and goals — A daily goal, streak counter, and a gentle reminder.
- Progress — Words learned, mastery per topic, review due today.
- Offline — Content bundled with the app; learners are often on limited data.
Build it with App Builder Agent, step by step
Paste real content in the first message; structure follows content, not the other way round.
- Create a mobile app project. Offline lessons, audio and reminders suit a native app.
- Describe the course and paste a sample lesson. Language pair, level, lesson topics, and one lesson’s items.Build a language app called Lingo for Bengali speakers learning English. Levels: Beginner (10 lessons), Intermediate (10). Each lesson: 12 words/phrases with Bengali meaning, an example sentence and audio via text-to-speech. Flashcards with spaced repetition (again/hard/good/easy). Quizzes: multiple choice, type the word, match pairs. Daily goal 20 cards, streak, reminder at 8 pm. Progress per lesson. Content bundled offline. Friendly blue and yellow design. First lesson: Greetings — hello, good morning, how are you, thank you, please, sorry, yes, no, my name is, nice to meet you, goodbye, see you.
- Do one lesson in the simulator. Check the flip animation, the quiz types and the review scheduling: rate a card “again” and it should come back within the session, rate it “easy” and it should disappear for days. Try the type-the-word quiz with a capital letter and a trailing space to see that answers are compared leniently. Adjust in plain words.
- Add speaking and listening. Speech recognition for pronunciation practice; listening quizzes.Add a Speak practice: show the phrase, record my voice, use speech recognition to check it and give a score, and a Listen quiz where I hear the audio and pick the meaning.
- Ship. Export the APK for students; publish the website version for practice on a laptop.
Prompts that work well
The same builder covers many pairs and purposes:
Common mistakes (and the fix)
- Reviews scheduled in whole days without a time zone. A learner in Dhaka who studies at 11 pm sees tomorrow’s cards appear at 5 am UTC. Ask for due dates in the device’s local time and “due today” to mean the local calendar day.
- Strict answer checking. “Good Morning” marked wrong against “good morning” ends streaks and motivation. Ask for case- and punctuation-insensitive matching, with accents optional for beginners.
- Streaks broken by a missed notification. If the daily goal resets at midnight sharp, one late night wipes a 40-day streak. Ask for a streak freeze or a grace period until 4 am; learners keep coming back.
- Content in the screens instead of in data. Twenty lessons typed into the code cannot be edited later. Ask for lessons in a JSON or CSV file the app reads, so adding lesson 21 is pasting lines.
- Audio that downloads on every play. Learners on limited data will not forgive it. Bundle audio with the app or cache each file after first play, and show the size of a lesson before downloading.
- Only one quiz type. Multiple choice alone teaches recognition, not recall. Mix in type-the-word and listen-and-pick from the first lesson; the agent will interleave them if you ask.
Make it feel finished
- Small lessons, big buttons; learners study in short bursts on phones.
- Ask for a “review due” badge on the app icon; it drives streaks.
- Start with text-to-speech, replace with your own audio later — the agent keeps the slots.
- Let users add their own words; it doubles retention.
- Show a “words mastered” counter on the home screen; it is the number learners screenshot and share.
Installing, publishing and next steps
Bundle the content and export the APK: nothing to host, and the app works offline. If you sell access, ask the agent for a hosted backend with accounts and a simple activation code — the platform provisions and hosts it with the project.
A website version of the first lesson is a good free sample for students to try before installing.
To get it to students, use Download APK in the Preview tab for a release-signed test build they can install from a link, and ask for a signed store build (APK plus AAB with your own package id and version; the keystore stays with the project) when you want a Play Store page — see the AI app builder page for the details. The quiz mechanics are covered on their own in how to build a quiz app without coding, and if your learners want explanations and practice generated on demand, an AI study helper app shows how to let the app call the AI.
The first app is built free after sign-in; unlimited APK builds and source export come with the $1.49 Member plan ($1.49 per 30 days), and bigger plans are one-time payments per 30 days rather than a subscription.

Frequently asked
Do I need to know how to code to build a language learning app?
No. You describe the language learning app in plain English and the AI agent writes real code (React Native for phones, React or HTML for websites). You can read and edit that code, but you never have to.
Can I install it on Android?
Yes. The builder exports a release-signed Android APK you can install directly or share; the same project can go through the Play Console for a store listing.
How much does it cost?
Starting is free: sign in and the agent builds your first version in the browser. Editing further with the agent, exporting APKs and publishing are part of the paid plans, which are priced per month with no long-term contract.
Will the language learning app work offline?
If you ask for data to be stored on the device (the default for personal apps), the app works without a connection. Apps with a hosted backend need a connection for shared data.
Can I use my own audio recordings instead of text-to-speech?
Yes. Start with the device’s text-to-speech so every item has audio from day one, then paste links to your hosted MP3s and the agent swaps them in per item; the content stays bundled for offline use. Speech recognition for pronunciation practice also works in the preview and the APK.
