How to build a language learning app for iOS
What a language learning app needs
- A lesson model with words, phrases, and short exercises
- A spaced-repetition review engine that schedules cards by how well you knew them
- Multiple question types: multiple choice, type the answer, and match pairs
- Audio playback for pronunciation, using built-in text-to-speech or recorded clips
- A daily streak and goal, with a reminder notification
- Progress per lesson and per skill so people see they are improving
- Offline access so review works without a connection
A focused first version is one language, a set of lessons, spaced-repetition review, and audio. That is enough to be genuinely useful.
How to build it with AppFlight
Describe it in plain English, for example: "A language learning app with short lessons of words and phrases, a spaced-repetition review system that schedules cards, multiple choice and type-the-answer questions, audio pronunciation, a daily streak with a reminder, and progress tracking per lesson." AppFlight plans the screens, generates native SwiftUI, and launches it in a live simulator so you can run through a lesson and a review session. You iterate by asking for changes in plain language, like adding a listening exercise or a leaderboard.
Monetization for a language learning app
The standard model is a free tier with a paid upgrade. Free users get a daily lesson cap or a limited number of review cards; the subscription removes limits and unlocks all lessons, offline access, and extra practice modes. Add a RevenueCat paywall for subscriptions, and use Superwall if you want to test paywall designs without shipping updates. Education apps often price seven to twelve dollars a month, or fifty to eighty a year, with a free trial. Because progress builds over time, an annual plan tends to convert and retain better than monthly.
Shipping it to the App Store
When the app is ready, AppFlight signs the build, uploads to TestFlight so you can test on your own device, then submits to the App Store with metadata and screenshots from the simulator. If Apple rejects the build, AppFlight reads the reason, fixes the issue, and resubmits. Apple reviews every app, so a submission is not the same as an approval. If your lessons include audio or text licensed from others, make sure you have the rights, since content ownership is a common cause of rejection. The whole pipeline runs without you opening Xcode.
FAQ
Do I need to code to build a language learning app?
No. You describe the app in plain English and AppFlight generates native Swift and SwiftUI. You can read and edit the code if you want, but you do not have to.
Can it speak the words out loud?
Yes. iOS includes built-in text-to-speech through AVSpeechSynthesizer for many languages, so you can play pronunciation without recording audio yourself. You can also bundle recorded clips for higher quality. AppFlight can build either approach in.
How do language learning apps make money?
Most use a free tier with a subscription for unlimited lessons, offline access, and no review limits. A RevenueCat or Superwall paywall is the common setup, often around seven to twelve dollars a month or fifty to eighty a year.
