Card 1 of 3
How it works
Three steps, and no cramming.
Fifteen minutes a day. The plan decides what you see.
Step 2
A plan that knows what you would forget
Every question you answer comes back just before you would forget it, scheduled by FSRS — the same spaced-repetition scheduler Anki uses. Less time studying, more of it staying.
Step 3
The reason you come back tomorrow
Your pet grows every time you study. Showing up is the only part left to you — the plan decides the rest.
The research
None of this is our clever idea.
Two findings have held up in classrooms for decades. Most study apps use one. petso is built on both.
Retrieval
Being asked beats being shown.
Answering a question builds memory faster than rereading the explanation. It is why every session asks before it tells, and why the explanation only appears after you have committed to an answer.
Spacing
Gaps beat cramming.
The same half hour spread over three weeks is remembered far longer than one evening of it. It is why reviews come back to you on a schedule instead of when you happen to feel like it.
Scheduled by FSRS — the same spaced-repetition scheduler Anki uses.
A pet, not a guilt trip.
Your pet grows when you study. It never dies, never shames you, and one missed evening does not undo a month — pick it up tomorrow and nothing is lost.
