I love this! The UI is great, adding boxes and cards is easy, and I really appreciate that it is just a leitner box! And I really appreciate that the free version doesn't have distracting ads! The one thing keeping me from saying 5 stars is that I would appreciate if there were some way in the free version of backing up your cards. I've got hundreds of cards all at different levels, so starting from scratch if I lost my phone would be devastating. Maybe just manual backups could be free?

Have to pay for import functionality. CSV only imports 1 row. Excel format errors out.

That usually happens when the file is being a bit “moody” — either it has errors or the format isn’t quite right 🙂 If you’d like, we can take a look—just reach out to support through the app. And hey, dropping a 1-star rating for that is a bit harsh 😄

The app is good, the price is also good, but it could be amazing. The input is not the best, you can create card by card and not using a csv for example. You cannot use colors, etc. And also, if you have a lot of new cards, you must finish them in order to practice the other levels since its random. It would be very nice that the app prioritize the higher level cards as the true Leitner System. Overall good, but it could be improved, because of this moved to Anki :)
