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

This page summarizes the projects mentioned and recommended in the original post on /r/Anki

  • InfluxDB - Collect and Analyze Billions of Data Points in Real Time

  • fsrs4anki

    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

    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.

  • InfluxDB

    Collect and Analyze Billions of Data Points in Real Time. Manage all types of time series data in a single, purpose-built database. Run at any scale in any environment in the cloud, on-premises, or at the edge.

  • anki

    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

    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.
