Just a suggestion

It's clear that the developers have worked very hard to make this app possible for everyone.
Just one suggestion in the future: maybe a built-in Spaced Repetition (SR) feature for the flashcards?

Thank you!

Developer Response ,


Thanks much for the kind words. 🙏

You’re absolutely right about spaced repetition. There's a first small step in 3.0.0, and more to come as we figure out what’s next.

To me it’s a useful stuff

At first I never thought my Burmese language was included, like most other language apps.
The error as to Burmese language is really rather rare. I appreciate the developer of this work. Thanks a lot.

New version

Not good

Developer Response ,

Sorry to hear you didn't like the new version. Did 2.9.3 add what you need?
