Just what I need!
I love this app so much, it has really helped me grow my Polish vocab. The ability to add my own cards to study is perfect, and the ads are always very reasonable (not super long or in the way). I really appreciate the work you have put into this app (and all of your other language apps). It does exactly what it was designed to do: teach vocab through SRS. I wish you had a similar app for Croatian, but beggars can’t be choosers. Thanks for this and keep it up!
