If you’re interested in SRS algorithms you should visit the site of the guy who basically invented them [0]. Most SRS algorithms seen in apps today are based on one of the super memo algorithms in one shape or form. Anki was based on SM2, which was already outdated in terms of supermemo algorithms when released, but was chosen due to its simplicity. 0: https://supermemo.guru/wiki/SuperMemo_Guru#Memory https://supermemo.guru/wiki/SuperMemo_Guru#Memory

SuperMemo is proprietary software, and only works on Windows. Anki's algorithm is deemed adequate by most, and the benefits of newer algorithms which introduce more complexity are marginal/questionable.

  From experience, my rep load in SuperMemo was half of what it'd have been in Anki for Japanese. over time, gap would've exploded. Being the only people with 30 years of good data makes a pretty big difference

    But is your retention the same? These algorithms can be tuned, and obviously the amount of repetition to retain 95% of info is higher than retaining 90%.

  Parent post was talking about algorithms. I linked to the site containing articles and research written by the person who created the algorithms. It’s completely separate from supermemo the app. If you’re looking at SRS algorithms, it’s worth looking through, for no other reason than to see what the flaws of the SM2 algorithm (used by Anki) are.

  I’ve been using SuperMemo for almost 17 years every single day, started using it before Anki even came out. Too invested in my SuperMemo flashcard collection to jumó ship. I am 100% satisfied with SuperMemo 18’s algorithm, I’ve upgraded every single version since this is kind of my thing now. I’m a guy that does flashcards every day and can almost perfectly memorize everything I put in it.
