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

Hey everyone — building Retrieve, a native SwiftUI flashcard app for iOS.

The pitch: AnkiMobile is powerful but clunky and dated. Brainscape locks AI behind a subscription. Flashcards Deluxe can't search across decks. Retrieve aims to fix all three — native SwiftUI, the real FSRS spaced-repetition algorithm, a Home/Lock Screen widget showing cards due, and cross-deck search. Free to use, with a one-time unlock for premium features (no subscription).

Built solo, currently in App Store review. Would love feedback from anyone who's used Anki or other flashcard apps — what's missing, what would make you switch?
