A personal place to learn. Flashcards, focused review and the freedom to study wherever life takes you.
Learning tools can become another thing to manage. Remnesa brings the focus back to a simple question: what would you like to remember?

Personal decks · Rich media · Import & export
A focused review session, with spaced repetition helping decide what comes next. The interface makes room for the thought, not just the tap.
Spaced repetition · Focused sessions · Thoughtful feedback
Your material stays on the device. Open the app and study without signing in. An account adds sync when you want it.
On-device storage · Guest experience · Optional sync
React Native · Expo · TypeScript
Study, deck editing and rich media share one application foundation. Platform integrations handle files, audio, haptics and navigation, while domain logic stays separate from the interface.
SQLite · React Query
The device is the working source of truth. Schema migrations, foreign keys and exclusive write transactions protect the local model; React Query coordinates reads and cache invalidation. Guests can use the product without an API.
FSRS · Persisted review events
The scheduler tracks each card’s difficulty, stability and due date. Again, Hard, Good and Easy produce the next review state locally, while a review-event history supports replay of the learning state.
NestJS · PostgreSQL · Kysely
Optional accounts add synchronization through a separately deployable API. Local outboxes queue changes; versioned mutations, retry checks and explicit conflict responses handle the boundary between device and server.
Local media · Versioned backups · Anki import
Images and audio live alongside study material. Structured backups preserve decks, notes, review data and media references. Import pipelines bring in Anki packages and text material without making the study core depend on cloud storage.
