Retrieve — native iOS flashcard app, one-time purchase, no subscription

Built Retrieve, a native SwiftUI flashcard app for iOS. Currently in App Store review.

Why it exists: AnkiMobile is powerful but dated and clunky. Brainscape locks its best features behind a subscription. Flashcards Deluxe can't search across all your decks at once. Retrieve fixes all three — the real FSRS spaced-repetition algorithm, a Home/Lock Screen widget showing cards due, and cross-deck search built in from day one.

Free to use, with a one-time unlock for premium features. No subscriptions.

Would love feedback from anyone who's used Anki or other flashcard apps — what's missing, what would make you switch?
