Leitra

Leitra is a flashcard app built on the Leitner system — a proven spaced-repetition method that schedules your reviews at scientifically optimized intervals so you remember more with less effort. HOW IT WORKS Cards move through 6 progressive boxes based on how well you recall them. Get a card right, and it advances to a longer interval. Get it wrong, and it returns to Box 1 for more frequent review. By the time a card reaches The Vault (Box 6), it's part of your long-term memory. Review intervals: 1 day → 2 days → 4 days → 9 days → 14 days → 30 days FEATURES • Create flashcards with rich text formatting — bold, italic, underline, and color • Organize cards into categories with custom emoji icons • Track your learning journey with a visual progress dashboard • Import card decks from Excel spreadsheets for quick setup • Back up and restore your entire library • Set daily study reminders so you never miss a session • Choose between light, dark, or system appearance PRIVACY FIRST All your data stays on your device.
