User reviews

Problem in IOS17

There is a problem in iOS 17 where the app closes when I try to add a new word.

All is Lost

Unfortunately, after many years and over 2200 flash cards created, I cannot transfer them to my new phone. 5th Box claims you can WiFi transfer all of your cards but it appears this is a ploy to gain customers. Something to remember when looking for a good flash card app.

Where have you been?

Iโ€™m a college professor, and I coach my students on spaced repetition. This is far and away the best, most helpful app available.

Helpful application

A very useful application, but now in IOS14 and 15, it would be better if the update the app with a widget feature in which it would be possible to review the content of each part on the home screen.

Perfect

Hello . Thank you for your good app. I wish other languages would be added to it.
