MyLeitner

Learn what you want, and most importantly: never forget it again.

MyLeitner uses the Leitner system, a spaced repetition method proven since the 1970s. The principle is simple: a card you've mastered appears less and less frequently, while a card you struggle with appears every day. You no longer waste time on what you've already learned, and you catch up on what you've missed.

THE PRINCIPLE
Your cards travel between five boxes. The first one appears every day, the last one once a month. A correct answer moves the card forward, a hesitation moves it back. You decide how many times a card needs to be validated before it's moved to a different box: five by default, more if you want to be sure.

CREATE YOUR OWN CARDS
• Question on the front, answer on the back
• Add images to both sides: diagrams, photographs, formulas
• Organize your cards by theme, each at its own pace
• Label them for easy reference
• Import a batch of cards from a CSV file
• Edit or delete a card at any time without losing your progress

STUDY AT YOUR OWN PACE
Two ways to work: review mode, which only shows cards due today, and random mode, for a no-holds-barred test. Each card offers three honest answers: I don't know, I know it fairly well, I know it. Your honesty is what sets the rules.

REMINDERS THAT SILENCE WHEN NEEDED
A reminder in the evening if you haven't completed your set, a preview in the morning showing you the first question. On days when you're up to date, MyLeitner doesn't notify you. You choose the time, or you turn everything off.

SHARE THEMES
Browse themes published by other users and add them to your collection. The copy is yours to keep: you can correct it, add to it, or remove anything that doesn't apply to you. Publish your own if you wish—or keep them private, which is the default setting.

To get you started, a "World Capitals" theme is already available: the 193 UN member states, complete with their flags.

TRACK YOUR PROGRESS
See at a glance how many cards are waiting for you, what you've mastered, and how your cards are distributed across the boxes.

YOUR DATA IS YOURS
No advertising, no tracking, no resale. Request a complete copy of your data at any time, or delete your account: erasure is immediate and permanent.

An account is required to access your cards and your progress.

Happy studying!
