My Very Last Review for this App

Shado Guy

Great App. I enjoy the constant updates and the effort by developers to continually make it better. Thank you.

However, I believe this is my third favorable review for this same app. There is a message from the app which states that the app's review requests are reset after every update. I am giving one last review simply to get rid of the message.

This "reset" is a flawed practice. Get rid of it - rely on new customers' reviews - because pushing the patience of the app's veteran users will work against you in this forum.

Still the best chess app out there, but even that has limits.

Dear Developer, January 24, 2018,
You have indeed updated the constant review requests. There are also many, many new features since my last app review.
Ironically, I forgot to reflect this in the review section because of the lack of reminders. Five Stars! Best Chess App on the planet. Thank you!

Developer Response

Hello, we hope you will try the latest version. We removed the old review mechanism and added a tonne of features.

I like it


The update is just amazing but the bugs need to be fixed the crashing in one of the games of the database is pretty bad. I know this update just came out but that was what I realized. Basically it just freezes then it crashes. But the updates great keep on doing it mastersoft Ltd.

The databases in the world championships were crashing for sure I dont about anything else though.

Developer Response

Hello, thank you for the feedback! Which database is crashing on you? We will fix it asap.



App won’t open after the last update. Where’s the email to contact support? The latest update fixed the problem. Other than that this was is a great Chess App.

Developer Response
