Remember every word you learn
Spaced repetition shows each card at the exact moment you're about to forget it. A few focused minutes a day beats hours of cramming — and with five visible boxes, you can see exactly how it works.

In the app this card would now rest in your Mastered pile. That's the whole method — no algorithm, no mystery.
spaced repetition you can actually see — this is the real study mechanic
Fifty years of memory science, five simple boxes
In 1972, Sebastian Leitner turned proven memory research into the simplest spaced-repetition system ever designed. We put it in your pocket — unchanged and un-hidden.
Review just before you forget, and the curve resets — flatter every time.
Reviewing just before you forget resets the curve — spacing puts your minutes only on the words that are slipping.
Five boxes. Five minutes a day.
The whole system fits in one sentence — and on one screen.
You pick which box to study. Sessions are one pass and actually end — built for the bus stop, not the library.
Everything you need to make words stick
Five boxes, zero mystery
The Leitner system — the original spaced repetition — laid out where you can see it. Right climbs, wrong resets.
Sessions that end
Pick a box, tap through it once, done. No endless review queue guilt-tripping you at midnight.
Tap, don't type
Multiple-choice answers with instant feedback — the correct answer flashes green the moment you miss.
Free means free
Reviewing your cards will never be paywalled. Ever. Studying is free forever, on every plan.
Pay once, own it
$29 lifetime, and that's it. Compare: about $5/month, forever, elsewhere.

Questions, answered honestly
Is the free plan really free forever?
Yes. Reviewing your cards will never be paywalled — the free plan includes unlimited studying with up to 3 decks and 100 cards. The one-time Lifetime upgrade only unlocks higher limits and extras like CSV import and full statistics history.
How does the first-100 discount work?
The $29 lifetime price is a founder discount reserved for our first 100 users. Once those spots are gone, the price goes up — but if you lock it in early, you keep it forever.
What happens if I skip a few days?
Nothing scary. Unlike algorithmic apps that bury you in a 400-card backlog, your boxes simply wait where you left them. Pick a box, do one pass, done — the whole system is visible, so you stay in control.
How is this different from Anki or Quizlet?
Anki's algorithm is powerful but opaque, and Quizlet locks reviews behind a subscription. We use the original Leitner method: five boxes you can see, sessions that end, and a single $29 payment instead of rent.
Can I bring my existing decks?
Yes — Lifetime includes CSV import, so you can migrate from Anki or Quizlet in minutes. And CSV export is free for everyone, so your data is never held hostage.
Why five boxes instead of a smart algorithm?
Because control beats mystery for habit-building. You always know why a card appears and what progress looks like — cards climbing boxes. It has been the most-taught memory method on earth for fifty years.
What if I buy Lifetime and change my mind?
There's a 30-day money-back guarantee. Ask for a refund within 30 days and you get your money back, no questions asked.
