The Modern Spaced Repetition App for Serious Learners
Master any subject in half the time. Powered by the FSRS algorithm, wrapped in a beautiful, distraction-free interface.
No credit card required
Your Focus Should Be on Learning, Not Fighting Your Tools.
Most flashcard apps are either powerful but painful to use, or pretty but shallow. You deserve both.
The "Configuration" Barrier
Why does powerful software have to look like a spreadsheet from 1998? Steep learning curves, confusing buttons, and needing 20 plugins just to get a Dark Mode that doesn't hurt your eyes.
"I spend more time fixing my card templates than actually studying."
Beautiful Out of the Box
No CSS hacking required. SpaceRep features a polished, modern UI with intuitive controls that just work. Dark mode, clean typography, and thoughtful design — all included.
The "Review Hell" Anxiety
The "study every day or else" model creates massive anxiety. Old algorithms are rigid — miss a weekend due to life, sickness, or burnout, and you return to a punishing backlog of 500+ reviews.
"I missed three days, and the backlog was so stressful I just quit entirely."
Resilient Scheduling
Powered by FSRS, SpaceRep understands that you're human. We smooth out your backlog and prioritize high-value cards so you can catch up without the panic.
The "Jank" & Distraction Fatigue
It's impossible to enter a "flow state" when you are dodging video ads, fighting sync errors, or dealing with software that feels like it's "perpetually in beta."
"I lost my rhythm because the sync failed... again."
Rock-Solid Stability
Native performance, distraction-free design, and seamless background sync. No ads, no lag, no beta-testing on your time.
The FSRS Advantage: Study Less, Remember More.
The Free Spaced Repetition Scheduler (FSRS) is the first major leap in memory algorithms in 20 years.
Adaptive Accuracy
Legacy apps assume everyone learns the same. SpaceRep learns you. It analyzes your memory patterns to predict the exact moment you're about to forget.
30% Efficiency Boost
By cutting out unnecessary reviews on cards you already know well, SpaceRep saves you an average of 20 minutes for every hour of study.
