User reviews

Defective app

This app is full of annoying glitches that make working with the ches opening stressful and irritating. I tried all sorts of ways to remove these annoying bugs but seem organically fixed and untreatabe.

Response from developer

Please send more details about the bugs to chessopenerapp@gmail.com and we will fix them as soon as possible. Thanks for the feedback!

Best Chess Openings app!

This is an outstanding application for learning chess openings and for setting up, storing and practicing the ones that you prefer.
It would be useful to include the five most often used openings as a starting point for beginners, with comments if possible.

Fine tuning needed

The overall app is great but many things aren’t friendly user.

The way we add Openings in the Repertoire can be messy very quickly when you use Opening Tree —> Related openings.

In the opening tree, the opening title at the top of the screen doesn’t follow the actual position. If you choose exemple 1.e4 c5 2.Nf3 the title say Sicilian Defence which is correct, then I choose d6 which is Sicilian and then I click back to Nf3 to comeback, the title stay at Sicilian instead of Sicilian defence.

In the repertoire removing openings is a nightmare. You have to select individually each opening then choose remove. There’s no options to delete multiple items in same time or just delete de main opening trees and all the variations get deleted etc..

Also the train mode could be really more friendly user. Just an exemple the title should change on each move showing where we are in the variation etc..

Etc... Etc..

Many other things that make me delete this app and not buy the Pro version.
