How to make a flashcard app for iOS
What a flashcard app needs
- Decks and cards, with a front, a back, and optional images or audio
- A review session that shows one card at a time and lets you flip it
- A grading step after each card, for example again, hard, good, or easy
- A spaced repetition schedule that uses those grades to set the next due date
- A due-today count and a way to see overall progress per deck
- On-device storage with SwiftData or Core Data so reviews work offline
- Optional iCloud sync and deck import or export
Get the review loop right first. A clean flip, a grade, and a sensible next interval is the whole product. Themes and stats come later.
How to build it with AppFlight
Describe it in plain English, for example: "A flashcard app where I create decks of cards with a front and back, study a deck one card at a time, flip to see the answer, grade each card as again, hard, good, or easy, and have the app reschedule cards using a spaced repetition interval so due cards come back at the right time. Show a due-today count per deck and store everything on device." AppFlight plans the screens, generates native SwiftUI, and launches it in a live simulator so you can run a study session immediately. You refine the scheduling and layout by asking for changes in plain language.
Monetization for a flashcard app
The standard model is a free tier with a paid upgrade. Free users get a limited number of decks or cards; the subscription unlocks unlimited decks, detailed retention stats, custom scheduling, and cross-device sync. Add a RevenueCat paywall for subscriptions, and use Superwall if you want to test paywall designs without shipping an update. One consideration specific to this niche: if you let users share or download premade decks, be careful about copyrighted study material, since you are responsible for content distributed through your app.
Shipping it to the App Store
When the app is ready, AppFlight signs the build, uploads to TestFlight so you can study 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, but the whole pipeline runs without you opening Xcode.
FAQ
Do I need to code to make a flashcard app?
No. You describe the app in plain English and AppFlight generates native Swift and SwiftUI. You can open and edit the code if you want, but it is not required.
Can it do spaced repetition like Anki?
You can ask AppFlight to implement a spaced repetition schedule such as Leitner boxes or an SM-2 style interval. It will not be Anki, but the core idea, showing cards just before you forget them, is straightforward to build.
How do flashcard apps make money?
Most use a free tier with a subscription that unlocks unlimited decks, detailed stats, and cross-device sync. A RevenueCat or Superwall paywall is the common setup.
