What does spaced repetition change as you learn?
The interval between reviews, based on how well you recall a card.
In a study session, you would then rate your recall to schedule the next review. This example does not save progress.
It remembers
so you can build.
You don’t have to keep track of what to review next. Your recall ratings shape when each card returns, keeping earlier learning in reach as you build on it.

Answer the cards that are due. Rate your recall and let the schedule adjust. When the queue is done, so are you.

Before you begin.
Can I start for free?
Yes. The free plan includes three active deck slots, access to public decks, the full scheduler and progress tracking.
How does the review schedule work?
After you reveal an answer, you rate your recall. The scheduler uses that rating to set the next review. Cards you find difficult return sooner.
Can I make my own decks?
Premium includes deck authoring and forking, so you can create cards or adapt a public deck to your needs.
Do I have to study every day?
Your due cards remain in your review queue. When you return, you can pick up with the cards waiting for you.
Make a little room
for what stays.
Start with one deck. Make a little space for something you want to understand.
