User reviews

Can’t believe this is free

I was searching for so long a good app or website to practice openings and I always herd people saying chessreps or chessable, but they are actually bad and not for people who want to learn an opening they already chose. Even though I know there is a limit to the free version, I haven’t seen a single paywall or ad since I use it. The way you can add moves is very good with nice insights, though the rest of the app may not be very intuitive (you get used to it after like a day so its not that bad). The only thing i can criticize is that there is no no-wifi mode to practice, which I think could be a great and easy addition

Good Stuff

Works!

Really awesome

Just a really cool and awesome way to help you learn and expand your opening repertoire

OK

Seems like an okay chess app, it’s cool how they show you the mistakes from your games. UI is horrendous though

Great app

Nice app that works as a really good companion to chess.com. I’ve not paid to upgrade anything on this app so consider me an unpaid review. I’m not even sure what the premium features do but I imagine they’re worth it, because the features the app provides simply for free is amazing!

My favorite thing is how it can show you moves / openings and you can try and create plans for when opponents move their pieces in different ways. I love how it connects with chess.com and shows me opening mistakes I had made! 5/5
