I'd have to see some serious stats to believe whatever SRS algorithm you use is better than FSRS (which is supported in Anki). Stats for FSRS here (and elsewhere) [0].

Yeah as someone working on educational software, anything hand-rolling their own SRS is a pretty big red flag. Beating FSRS is going to be next to impossible, especially FSRS with parameters optimized from your users’ review history.

  FSRS is so cargo-culted. It's just an algorithm, claiming that any algorithm can't be improved is ridiculous.

    Actually, we have found some algorithms which outperform FSRS[1]. Unfortunately, it's hard to deploy them in user's local device.

  The app is using the same Anki FSRS algo its open source https://github.com/open-spaced-repetition/fsrs4anki https://github.com/open-spaced-repetition/fsrs4anki Agreed would be swimming against the tide rolling a custom one. Anki's is awesome! This app functions much the same just makes card generation MUCH faster than Anki.

not OP. I have a competing product with an ad-hoc algorithm that I 100% believe is better than FSRS (tested it for months or real practice) But what you ask is not feasible, neither I nor OP have 700 millions of reviews to stack up against FSRS. I have my own experience and a bunch of simulations, and if FSRS were better I would have switched to it. The reason in my case btw is that FSRS is generic, mine is tailor made for languages - big difference.

  You don't need to beat FSRS with 700 millions of reviews. You can collect thousands of reviews for months and compare the ad-hoc algorithm with FSRS on those reviews.

It uses the same FSRS as Anki. You can see some of the logic in my open source version of the app here https://github.com/Amber-Williams/language-flashcard-app-gpt4 https://github.com/Amber-Williams/language-flashcard-app-gpt... Anki uses this FSRS which is an open sourced algorithm https://github.com/open-spaced-repetition/fsrs4anki https://github.com/open-spaced-repetition/fsrs4anki
