Remember more
by revising less.

Every card comes back to you just before you would forget it. That is the whole principle of spaced repetition, and that is what the app does.

Question / answer

Define a function that returns the square of n? 

def square(n):
    return n * n

Rate the card, the app picks the next date.

The method

A card comes back at the moment it is about to slip away.

The app schedules your revisions with FSRS, the reference algorithm in spaced repetition. A card you have mastered comes back in a long while, a fragile one comes back soon. You have nothing to configure for this to work.

The same card, rated “Good” every time

Typical intervals

rated “Again”: replayed within the session

Swipe to rate

Four directions for Again, Hard, Good and Easy. The buttons stay there if you prefer them. In practice, a session is done with one thumb.

Algorithm tuning Premium

Target retention rate, daily cap, maximum interval. If the defaults suit you, leave them alone.

Honest statistics

Revision history, workload forecast for the coming days, cards that are new, learning and mastered. Nothing gamified to excess.

Six card types

What you revise decides the shape of the card.

Front and back, or reversible, as you like. Every card goes through the same scheduling engine.

Text

The classic front and back, or reversible to revise both ways.

Image

A photo, a diagram, a painting. The card carries the image full width.

Audio

Record the pronunciation from your phone, or import a file.

Fill in the blanks

Hide one or several words in a sentence and recall them from memory.

Image occlusion

Hide areas of a diagram, one at a time. Ideal for anatomy or cartography.

Multiple choice

Several options, one right answer. The rating stays the same.

Where we stand

No card is generated automatically.

The content comes from people who wrote it. That is a choice, not a technical limit. No ads, no invasive tracking, and the core of the app stays free.

  • No ads

    No banners, no video to watch before you can carry on.

  • No AI

    No card generation. What you revise was written by someone.

  • No invasive tracking

    The bare minimum needed to fix bugs, nothing sold on.

  • The core free, for good

    Revising, creating, sharing. That foundation will not move behind a payment.
