Cogni is a flashcard app with FSRS spaced repetition, AI flashcard generation and Anki deck import. Study on iPhone, iPad, Android and the web: your decks and progress sync through one account, and reviews work offline. MAKE FLASHCARDS WITH AI Upload a PDF, photograph your notes or textbook pages, upload a lecture recording, paste text or type a topic. Cogni drafts question-and-answer and cloze cards. You check the drafts and keep the ones you want. FSRS SPACED REPETITION Every card is scheduled with FSRS, the open-source algorithm that predicts when you are about to forget. After each answer, rate your recall (Again, Hard, Good or Easy) and see when the card comes back. Each day you review only what is due. IMPORT YOUR ANKI DECKS Save an .apkg file in Files, tap + in Cogni and choose “Import .apkg”. Cards, subdecks, cloze cards, images and audio come with it. Anki's review history stays in Anki: FSRS builds a new schedule from your answers in Cogni. NOTES NEXT TO YOUR CARDS Generate study notes together with your cards and read them in Cogni on the web, linked to the cards they produced. READY-MADE DECKS Browse a library of 5,000+ decks for languages, medicine, anatomy and more, add a deck and start studying.

Verdict
The clearest difference is in-app purchases: Sevius at none against Cogni's 9. Sevius also leads on rating (5.0 vs 4.7) and review sentiment (45% vs 36%). Cogni's advantage is update cadence (weekly vs every 6 months) and ratings volume (1.7K vs 1). On price, ads and device support there is nothing between them.

Both are free to download. Cogni sells 9 in-app purchases, starting at $4.99 per month. Sevius asks for nothing beyond the download.
Sevius holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Cogni has 1.7K ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 45% of Sevius's written reviews are positive against 36% of Cogni's.
Sevius ships an update every 6 months, Cogni weekly. The most recent releases landed on November 1, 2026 and November 8, 2026 respectively.
