Great looking app! It would definitely replace my current flashcard app but there's just some basic things missing that legacy apps provide. Not possible to import just a list of words or own csv files. Only one word at a time, this must be fixed asap. Cannot manually add images or request new ai image.

A hidden gem! I see that there are basically no reviews - time to write one! It's a pretty great app to learn any language. Give it a try! Looks like they are pretty new, but for me this has been the best flashcard app!

A+ for Engagement and Progress!! Using it to learn German and progressing quickly! I like the repetition aspect as I found that I'd normally forget a word pretty quickly after initially learning it and other apps wouldn't bring it back

Flashcards are done in a great way with good and flexible settings options. Very good for growing vocabulary. The app has a few bugs at the moment, but its a very early release that is going to be fixed and get better.
