- For
- Multi-device Anki users who care about review history
- Worth noticing
- The page says personalized FSRS fitting begins after about 400 reviews and runs from the same Rust-based scheduler across surfaces.
Field notes
The service represents reviews as immutable records containing the card, rating, time, and device, then derives scheduling from the accumulated log. Its stated implementation uses one Rust scheduler for native Apple clients and WebAssembly in the browser. The page also says Anki imports retain review history through stable GUIDs and that individualized FSRS fitting waits for roughly 400 reviews.
