1
Answer a card
Recall the answer before revealing it. That effort is part of what strengthens the memory.
FSRS spaced repetition
Review less randomly. Remember more reliably.
AlgoApp schedules flashcards according to what you know, how you answer, and when a memory is likely to need reinforcement.
The idea
Study close to the moment you might forget.
Spaced repetition places more time between successful reviews and brings difficult material back sooner.
2
Rate the result
Choose Fail, Hard, Good, or Easy based on how well you remembered.
3
Let FSRS reschedule it
The scheduler updates the card's memory state and chooses an appropriate next review date.
A plan you can see
From today's session to your finish line
Set a daily study goal, track momentum and streaks, inspect review history, and use estimated completion charts for FSRS decks and folders. Forecasts adapt to your material and pace.
Choose your retention
A deck's FSRS retention setting lets you balance how strongly you want to remember against how much review time you want to spend.
Review your way
Study one deck, a folder, or material across your library with OmniReview. Use tags, grades, and due filters when you need a focused session.
Why it works
Not every card deserves equal time.
A fixed rotation treats an easy definition and a stubborn concept the same. FSRS does not. It models each card separately so easy material can wait while difficult material returns sooner.
What FSRS means
FSRS stands for Free Spaced Repetition Scheduler. In AlgoApp, FSRS is a review mode that selects and schedules cards intelligently using their review history and your ratings.
Ratings are feedback, not grades
Fail, Hard, Good, and Easy tell the scheduler how recall felt. Honest ratings help the next interval match your memory. The goal is not to collect perfect scores; it is to build durable recall efficiently.
New cards fit into the same system
Cards you create manually, import, generate with AI, or add through image occlusion can all move into the same review flow. Creation and scheduling stay connected.
Give every review a reason.
Build a deck, answer honestly, and let AlgoApp shape the schedule around your memory.
