Ebbing: Spaced Repetition

Ebbing is a study app that keeps a record of what you've studied and tells you the best time to review it, based on the forgetting curve.

Just log your daily study in a simple interface, and Ebbing builds your review schedule automatically.
You can see at a glance what to review, and when.

No more wasting time on unplanned studying.
Ebbing helps what you learn stick.

◇ How It Works

Ebbing is built on the "forgetting curve," first described by the psychologist Hermann Ebbinghaus.
It models how people forget, and helps strengthen memory by spacing your reviews at appropriate intervals.
The retention rate shown in the app is an estimate based on this model, not a measurement.

◇ Ebbing Plus (optional auto-renewable subscription)

Ebbing Plus removes the limit on the number of materials and unlocks custom review intervals, schedule editing, and statistics.
Monthly and yearly plans are available, and the price is shown on the purchase screen. You can cancel your subscription anytime in your App Store account settings.
