It's a great online chess app but there is a bug that's bugging me. Occasionally (randomly) I get disconnected from the server even when I have exceptional 5g. That, ultimately, has cost me a few games. An update would be good, since the last one was Oct 2020.

Very good. I has such little, but important thing as the premove for playing online as well as offline. However, it does not have the option to set time control when playing offline against an engine. Otherwise I would give it 5 stars.

Very good app for my students training and tracking thier rating. I just like you to add more details to the save games after play like the level of engine strength played displayed and saved after the game so when I review thier games I know what engine level they play against with. I hope you make action about it. Thanks a lot and more powers!

What's new

App store policies does not allow to directly download binaries like chess engines, so now the app can only use Open Exchange (OEX) engines downloaded from the app store.
New column with a precalculated evaluation (at depth 16) in the "Search position in DB" results.
Fixed a bug sharing PGNs by email.
Fixed a problem with the move sound in some devices.
More options to the move animation time.
Set the default move animation time to 0.5s.
Set the default "Allow Premove" option to checked.
