What is spaced repetition?
Reveal the answer and move to the next card with the arrow. Each pass feeds the SM-2 scheduler, so practiced cards space out over time.
Card 1 of 1 · 1 due
Reveal the answer, then move on — each pass feeds the SM-2 schedule.
Reviews: 0 · Interval: 0 day(s) · Next: not scheduled yet
Fullscreen study shows one question at a time — your written answers stay hidden until you reveal them. Space reveals, arrow keys move between cards.
About this tool
Review a flashcard with a transparent SuperMemo SM-2 scheduling algorithm. Free, private and browser-based. Flashcards & Spaced Repetition runs in the browser on DevTools. There is no signup, and your input stays on this device unless the tool explicitly performs a live network lookup.
What this tool does not do
- Flashcards & Spaced Repetition is a free in-browser utility, not a hosted API. It does not keep server-side history and is not a substitute for production verification in your own stack.
