How to build a study app for iOS
What a study app needs
- Decks and cards, with front and back, tags, and optional images
- A spaced-repetition review flow that schedules each card
- A quiz or test mode for self-checking
- Progress tracking: cards due, streak, accuracy over time
- A daily review reminder via local notification
- Optional AI card generation from pasted notes or a topic
- A Home Screen widget showing cards due today
A working spaced-repetition scheduler is the heart of the app. Start with a simple interval model and refine it once people are using it.
How to build it with AppFlight
Describe it in plain English, for example: "A study app with decks of flashcards, a spaced-repetition review that brings cards back at the right time, a quiz mode, progress stats, a daily reminder, and a widget showing how many cards are due." AppFlight plans the screens, generates native SwiftUI, and launches it in a live simulator so you can build a deck and run a review session immediately. To generate cards automatically, AppFlight can connect OpenAI so a user pastes notes and gets a deck, with the key kept server-side in your own Supabase. You iterate in plain language, for example tuning the review intervals or adding image cards.
Monetization for a study app
The reliable model is a free tier with a paid upgrade. Free users get a limited number of decks; the subscription unlocks unlimited decks, AI card generation, detailed stats, and sync. Add a RevenueCat paywall to manage subscriptions, and use Superwall if you want to test paywall designs without shipping an update. Students are price-sensitive, so a low monthly price with a strong annual discount tends to convert best.
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, works on the fix, and resubmits. If you add AI card generation, disclose the third-party AI use. Apple reviews every app, so a submission is not the same as an approval, but the whole pipeline runs without you opening Xcode.
FAQ
What is spaced repetition and does a study app need it?
Spaced repetition schedules each card to come back right before you would forget it, widening the gap as you get it right. It is the core of most effective study apps because it makes review time count. A simple interval scheme is enough to start.
Can AI generate flashcards from my notes?
Yes. AppFlight can connect OpenAI so the app turns pasted notes or a topic into a deck of cards. The API key stays server-side in your own Supabase, not in the app.
How do study apps make money?
A free tier with a deck limit, and a subscription for unlimited decks, AI card generation, and detailed stats. A RevenueCat paywall is the common setup.
