Ratings and reviews

My main complaint now is that I cannot include the gender alongside the noun without losing the extra context the app provides. *Also it's very strange that the groups of cards you can use to pick from always seem to be in sorted order, and you have to either pick or discard, so you can only learn in alphabetical order? Gender support is lacking. Also, the translations are horrible, I have to use Reverso first before I can trust a translation.

This app definitely has potential. I've recommended it to others. But here's why I wouldn't give it five stars (for now): 1) The translations can sometimes be inaccurate. Their AI is not yet on par with, say, chatGPT or Gemini, so I'm finding myself sometimes fixing them with these and importing them here. 2) The listening mode would be awesome if it wasn't so laggy. Sometimes it stops by itself or takes forever to load. It doesn't count as practice either. An offline mode would be a plus.

The concept is good. However, I have chosen the german language, the "hard" deck of cards, and there are no articles for substantives, the verbs are not written in the infinitive form, translations are poor in some cases, and sometimes the example sentences have nothing to do with the word given. As a free app is ok, I wouldn't pay for it, given that it needs improvement. The AI feature is pretty useless.
