Very cool app. Chess.com costs too much and lichess is rather ugly and has barebones puzzle support. I like how you can choose different categories. Will be using this from now on. Btw you have "Egnlish Opening" misspelled.

Try lichess' beta app, it's much more user friendly, even if it's missing a couple of features.

For tactics I really like chesstempo.com. It has free, unlimited puzzles. It is to my mind superior for tactics training. It also has a comments feature which I really like.

Thanks for your generous reply and Oh my god how did I miss that, will fix in the next update.
