You believe in spaced repetition. You bounced off the complicated apps. sumi is for you. It keeps the science and drops the friction, so revision feels calm instead of overwhelming. HOW IT WORKS Make a deck or import one, then open sumi and review the cards it gives you that day. That is the whole routine. sumi uses FSRS, the modern spaced-repetition algorithm, to show each card right before you would forget it, so you remember more while studying less. CALM BY DESIGN An ink-on-paper interface with nothing competing for your attention. No streaks guilting you, no leagues, no badges. A gentle daily review you will actually want to come back to. BRING YOUR OWN DECKS Already have decks? Import them in seconds. sumi reads Anki .apkg files, plus CSV, TXT and JSON, so moving over takes minutes, not an afternoon. PRIVATE BY DEFAULT No account. No servers. Your cards, your progress and your history never leave your device. Nothing is tracked. Nothing is uploaded. Your data stays with you. BUY ONCE, YOURS FOREVER No subscription. Unlock sumi pro one time and keep it: unlimited decks and cards, unlimited imports, cram and reverse study modes, and detailed progress insights. Restore anytime. WHAT YOU GET - FSRS spaced repetition that schedules every review for the best long-term memory - Import from Anki (.apkg), CSV, TXT and JSON - Study offline, anywhere - Clean stats: retention, review history, cards mastered - Light and dark, easy on the eyes Calm, focused and entirely on your device. That is sumi.

Add locations to photos, see them on a Memory Map, place visual notes directly on each photo, and switch themes to reuse the same route for different topics. Use Memory Spots for exam prep, shopping lists, language practice, presentation cues, or anything that becomes easier to remember when it is attached to a place. Features: Create ordered albums from place photos Add photos from the library or camera Show geotagged photos on a Memory Map Add or change a photo location later Organize notes by theme Place sticky text, image notes, icons, number labels, and arrows on photos Zoom and pan while editing a photo Review notes in route order by album and theme Keep data local on your device Memory Spots is intentionally small and tactile.

Verdict
The clearest difference is in-app purchases: Memory Spots at none against sumi's 2. Memory Spots also leads on update cadence (every 5 days vs every 3 months). sumi's advantage is device support (3 vs 1) and iOS requirement (15.0 vs 17.0). On price and ads there is nothing between them.
