SPACED REPETITION · FSRS
Make remembering a daily habit.
Lorebyte is a spaced-repetition (FSRS) flashcard app for language learners and IT-certification candidates. Create on your Mac, review on your iPhone, and stay in sync across every Apple device via iCloud.
THE APP
One experience, every screen.
FEATURES
From learning to retention, in one app.
Smarter spaced repetition
The FSRS-5 algorithm schedules each card right before you'd forget it. Just rate recall as Again, Hard, Good, or Easy.
Build cards from what you have
Import from PDF, screenshots, images, CSV, or text. Japanese/English OCR turns pictures into cards.
Built-in translation help
Show a Japanese translation alongside English prompts. Toggle between English only, translation, or side-by-side while you study.
Synced across your devices
Decks, cards, and study history sync through iCloud—no separate account, and it works offline.
