Orbit’s current approach
Fixed growth factor (2.3x), same for every card and every user. No memory model — just mechanical interval multiplication. This is essentially the SM-2 family (1987 vintage).
What’s changed: FSRS
The big development is FSRS (Free Spaced Repetition Scheduler), which landed in Anki in late 2023 and is now mainstream. It’s based on the Three Component Model of Memory:
- Retrievability (R) — probability you can recall right now (decays over time)
- Stability (S) — how many days until R drops to 90% (the “strength” of the memory)
- Difficulty (D) — per-card intrinsic difficulty (affects how fast stability grows)
Key differences from what Orbit does:
┌─────────────────────┬───────────────────────────────────┬──────────────────────────────────────────┐ │ │ Orbit (SM-2 style) │ FSRS │ ├─────────────────────┼───────────────────────────────────┼──────────────────────────────────────────┤ │ Model │ No memory model, fixed multiplier │ DSR memory model │ ├─────────────────────┼───────────────────────────────────┼──────────────────────────────────────────┤ │ Per-card adaptation │ Same growth factor for all cards │ Difficulty tracked per card │ ├─────────────────────┼───────────────────────────────────┼──────────────────────────────────────────┤ │ Per-user adaptation │ None │ Learns from review history │ ├─────────────────────┼───────────────────────────────────┼──────────────────────────────────────────┤ │ Target retention │ Implicit │ Explicit (you pick, e.g. 90%) │ ├─────────────────────┼───────────────────────────────────┼──────────────────────────────────────────┤ │ Efficiency │ Baseline │ ~20-30% fewer reviews for same retention │ └─────────────────────┴───────────────────────────────────┴──────────────────────────────────────────┘
What’s worth considering
- FSRS adoption — it’s open source, implementable in ~100 lines, has a TypeScript implementation, and is trained on 700M+ reviews. The research backing is solid.
- Per-card difficulty — this is the lowest-hanging fruit. Some cards are just harder. Orbit’s flat 2.3x treats “What year did WW2 end?” the same as a dense biochemistry pathway. FSRS adjusts growth per card based on your history with it.
- Target retention rate — FSRS lets users pick their desired retention (default 90%). This is philosophically interesting for Orbit since different contexts want different retention — language vocab vs. conceptual understanding vs. exam prep.
- Content-aware scheduling — newer research and LECTOR (2025) use semantic similarity between cards to adjust scheduling. If you know card A, and card B tests a related concept, B’s interval can be adjusted. This fits nicely with Orbit’s provenance/source grouping.
- Deep RL approaches — DRL-SRS uses a Transformer to model learning trajectories. Interesting but probably overkill for now.
My take
The pragmatic move would be FSRS. It’s the “React of scheduling algorithms” right now — battle-tested, well-documented, open source, already proven at scale. The per-card difficulty tracking alone would be a significant improvement over the flat 2.3x multiplier.
The exotic stuff (content-aware, RL-based) is interesting but adds complexity that might not justify itself yet. Though content-aware scheduling could be a natural fit given you’re already building source/provenance grouping.
What’s your thinking — incremental improvement (add per-card difficulty to the existing scheduler) or go full FSRS?

Understanding Spaced Repetition for Learning
gwern.net
Spaced repetition is a psychological technique that enhances memorization by spacing out review sessions over time, rather than cramming. This method is particularly effective for learning large amounts of information, such as foreign languages and medical studies, and is supported by research on memory retention. The article reviews its applications, available software tools, and the underlying cognitive psychology principles.
