QuillFin

Notes that quiz you back. Keep notes in folders, turn them into quiz questions with AI, track practice problems, and let spaced repetition (FSRS, the algorithm behind Anki) bring each one back right before you would forget it. Works offline, syncs across your phone, computer and the web.

Coming soon to Google Play, with iPhone to follow.
