In the 1st anniversary of FSRS, I want to share some progress of recent works.

• fsrs4anki

  111 2,196 9.0 Jupyter Notebook

  A modern Anki custom scheduling based on Free Spaced Repetition Scheduler algorithm

  

Today, I released FSRS v4.6.2. In one year ago, I submitted my first commit for FSRS.

• fsrs-vs-sm15

  1 16 10.0 Jupyter Notebook

  Discontinued A simple comparison between FSRS and SM-15

  

Recently, I have run three comparisons for spaced repetition algorithms. They included SM-15, SM-17, SM-2, HLR, LSTM and FSRS series. The initial result shows that FSRS v4 beats all other algorithms in predicting probability of recall. It's a good news that the open-source algorithm can overperform SuperMemo's proprietary algorithm.

• WorkOS

  The modern identity platform for B2B SaaS. The APIs are flexible and easy-to-use, supporting authentication, user identity, and complex enterprise features like SSO and SCIM provisioning.

  1,149 17,204 9.8 Rust

  Anki's shared backend and web components, and the Qt frontend

  

Besides, dae, the lead developer of Anki, helped me integrate FSRS into Anki. We have merged FSRS Optimizer into Anki's main branch. The beta package will be released in a few weeks.

• Anki-Android

  229 7,844 9.9 Kotlin

  AnkiDroid: Anki flashcards on Android. Your secret trick to achieve superhuman information retention.

  

Good news again, AnkiDroid has completed its Rust backend update. FSRS will be supported in AnkiDroid in 2.17.
