I'd like a feature that reminds me of a particular piece of information at a logarithmic cadence so I can commit it to memory better by being reminded a few times within a few weeks/months, but then a nudge 6 months down the line, etc.
I built a tool to address that problem with Anki as the back-end[1], Idea being an always-on spaced repetition system can help us review the cards asynchronously.
It has been a huge quality of life improvement for me after I started using it, But I guess Anki and the HW requirements creates friction for a decent adoption of this system.
