01 / WHY SPACED REVIEW?
Forgetting happens.
Make room for recall.
What you learn can fade with time. The forgetting curve describes this change. Spreading out your study and trying to recall the answer can help you remember for longer.
Ebbinghaus brings difficult cards back sooner and spaces out the ones you remember well. Open the app and start with the cards that are due.
