KinetMemory is a modern spaced repetition app powered by FSRS — the most accurate scheduling algorithm. Bring your existing decks, keep every byte of your data on your own device.
No setup, no account, no cloud. Your decks never leave your device.
Open any .apkg deck file. Cards, cloze deletions, images and audio all come along. Works with the decks you already own.
Tap Again, Hard, Good or Easy. FSRS models your memory in real time — difficulty, stability and retrievability per card.
Reviews appear exactly when you're about to forget. FSRS cuts review load by 10-20% versus legacy SM-2 schedulers.
The state-of-the-art, open algorithm. Per-card memory model with 17 fitted parameters. Same engine trusted by millions of learners.
Import .apkg deck packages: basic cards, cloze deletions, nested decks, images and audio. Your library, your content.
Everything stays on your device. No account, no analytics SDK, no network calls. Your learning data is nobody's business.
Cloze deletion with multiple groups and hints. HTML formatting, tables, code blocks and images render beautifully.
See the next interval on every button before you tap. Understand what each grade does to your schedule.
Built with SwiftUI for iOS 17+. Dark mode, Dynamic Type, iPad support. Feels at home on your iPhone.
No account, no ads, no analytics SDK. Your decks and review history live only on your device. The developer cannot see any of it — there is nothing to see.
