alt Hacker NewsFor the record, btw, id DID download your app and I am going to spend some time using it. Other commenters here are talking about how spaced repetition isn't what's important, which is true in the same sense that you can't just use Duolingo to learn a language. But that doesn't make it useless.
Completely agree and I tried to avoid the Duolingo approach which optimizes for "engagement" over learning. I would love to hear any feedback you have after using the app for a bit: djoume [at] fata.dev
