Anki uses this FSRS which is an open sourced algorithm https://github.com/open-spaced-repetition/fsrs4anki
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.

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.
