Spaced Repetition

/speɪst ˌɹɛpɪˈtɪʃən/

Memora is a study app built around spaced repetition. Subjects hold topics, topics hold cards, and a lightweight SM-2 scheduler decides what's due each day — so you review what you're about to forget and skip what you already know. Every subject also gets its own infinite board: a dot-grid canvas to sketch, drop sticky notes, connect ideas with smart arrows and turn freehand scribbles into clean shapes. It's built entirely in SwiftUI and SwiftData, syncs over iCloud, and uses Apple's on-device models — no servers, no accounts.

Studying
The right card,
at the right time.

Placeholder for a flashcard being graded with Again, Hard, Good and Easy.

The right card, at the right time. An SM-2-style scheduler tracks an ease factor and interval for every card. Rate a card Again, Hard, Good or Easy and Memora reschedules it — failed cards resurface immediately, mastered ones drift weeks into the future.

Placeholder for a flashcard with a typed-answer field.

Type it out, get a hint. Cards can ask for a typed answer instead of a self-grade. When Apple Intelligence is available on device, a small language model reads your attempt and replies with one short, encouraging line of feedback — entirely on the phone.

Placeholder for a richly formatted flashcard with bold text and an inline image.

More than text on a card. Cards carry rich text — bold, italic and inline images stored as RTFD — alongside full-image cards and attached PDFs. Plain text stays the fallback, so import, export and iCloud all keep working.

Placeholder for a mastery ring filling up as cards are learned.

Know what you know. Every card moves through three mastery states — unseen, in review and mastered — surfaced as rings and bars across topics and subjects, so a glance tells you how far a deck has come.

Placeholder for a progress dashboard with a streak counter and activity heatmap.

Built to keep you coming back. A progress dashboard pulls it together: a study streak, a GitHub-style activity heatmap and a forecast of how many cards fall due in the days ahead — the gentle pressure that turns studying into a habit.

Memora Board
Think on an
infinite canvas.

Placeholder for the infinite Memora board canvas with a dot grid.

An infinite canvas per subject. Each subject opens onto its own Memora Board — a pan-and-zoom dot-grid canvas for mapping a topic out spatially when a linear deck of cards isn't enough.

Placeholder for a freehand stroke snapping into a clean rectangle.

Scribble becomes shape. Draw with Apple Pencil or a finger and a conservative recogniser turns confident closed strokes into clean rectangles, ellipses and lines — while anything ambiguous is kept exactly as you drew it.

Placeholder for two notes joined by a smart connector arrow.

Smart arrows that follow. Connect any two items and the arrow re-anchors to the nearest edge as you move them around, so relationships between ideas stay legible no matter how the board is rearranged.

Placeholder for tinted glass sticky notes grouped together on the board.

Notes, grouped and snapped. Liquid-glass sticky notes, ink, images and shapes snap to a grid and to each other, can be lassoed with a marquee, grouped, and exported — a full lightweight whiteboard, not just a sketchpad.

Placeholder for the same library appearing on an iPhone and an iPad.

Your whole library, on every device. SwiftData over CloudKit keeps subjects, cards and boards in sync across iPhone and iPad. A sync monitor watches the connection, and everything is designed to keep working offline first.

Placeholder for a Live Activity and a Home Screen widget showing due cards.

It meets you on the Home Screen. Study reminders, a Home Screen widget and a Live Activity in the Dynamic Island keep what's due in view — so a session is one tap away without ever opening the app first.

Placeholder for an import and export screen moving decks in and out of Memora.

Yours to take with you. Decks import and export as plain text, so your cards are never locked in — handy for moving an existing set into Memora or backing one up outside it.
