very good app, 5 stars for the effort but very annoying ui and options. 1) skip puzzle button is huge and clicked by mistake often. 2) sound comes out of phone and not ear buds so can't play it at night. 3) no option to turn off sounds and vibration. 5 stars if these were sorted. still keeping the app for now. good job otherwise.

Very nice app for practicing chess tactics and learning new skills. One annoying thing is "skip puzzle" button is to close to to rest of the buttons. Please change its location. I often hit it by mistake, when I am trying to go back or move forward, thus loosing elo score.

every time I try to log in, it deletes my progress. every time I restart the app, my progress is gone. it gives me way too easy puzzles until I set the parameters and it's really annoying to use. overall, I think they need to make some updates before I'll use it again
