Most flashcard apps run their AI in the cloud — they meter it, charge per generation, and send your notes to a server. Bowerbird doesn't. Its AI runs entirely on your iPhone, so card-making is fast, works in airplane mode, and your notes never leave your device. SNAP, CARDS, REMEMBER Point your camera at a page of notes. Bowerbird reads it on-device and turns it into clean flashcards — no retyping. Tables become cards instantly. Paste an export from another flashcard app, or a plain list of terms, and it splits them in one tap. STUDY THAT ACTUALLY STICKS Bowerbird schedules every review with FSRS-6, the modern spaced-repetition algorithm serious students rely on. See exactly when each card comes back, watch your memory strength grow, and keep a daily streak. EXAM MODE Set your exam date and Bowerbird plans backward — ramping up retention and making sure every card is seen before the big day. FREE FOREVER Unlimited decks, cards, scheduling, stats, paste import, and table scans. BOWERBIRD PRO Unlimited AI card-making and exam mode. - Yearly — $19.99/year, with a 7-day free trial - Monthly — $4.99/month - Lifetime — $39.99, one-time Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period.
