Chess Opener PRO

I have many options on PC for viewing databases and the opening tree of how often moves are played in a certain position. I have explored several apps for iPhone and iPad and none of them even come close to what I want. But this app really does it. It’s very close to chessx or scid on PC. I will use this for my chess students!

I have a pgn that other apps in android and window pgn readers can open, but this can’t?

This app is just good. A bit confusing to use but when you get the hang of it than it is just good. Crashes quite often and needs a update asap.

Really nice and you can review lines while training. I have tried them all and this is the best for the serious tournament player.

Amazing prep tool!

Very happy with this training tool. Well worth the money for the pro version. Could use iCloud integration to keep the databases the same on all devices. Easy 5 stars even without this.

I love this app. I’ve tried a ton of these opening trainers but they either showed refuted openings as the best lines or had minimal databases and weak engines. My only issue with the app is that when I try to import chess.com games I get an “invalid PGN” error. I’ve even tried removing the event data and just having the moves and I still receive the same error. Edit: Thank you to the developers for responding. Removing the brackets has fixed my issue! Thanks a ton

If this had iCloud sync across my devices for my repertoire then it would have 7 stars for me but for now I can only give it 5 stars 😆😆😆 You can import PGN for now or make the moves to add a new opening for training

Truly great app. I have the pro version. I use it every day. One grumble, sometimes it repeats the same variation for no apparent reason.

Ignore the 1-star ratings. I had given up on the iPad for opening training before I stumbled across this app. Excellent conception and implementation! Thank you!
