I have never heard of Chesscoin, and I doubt more than 10 pi-apps users have ever heard of it either. What's the purpose of this tool, apart from being a wallet for a random cryptocurrency? Please explain why anyone would want this. Is it used in chess tournaments somehow? I had a hard time finding any meaningful information about the project.

Whitepaper ChessCoin 032 with watermark.pdf

I attached our whitepaper regarding chesscoin, hope you will take a look at the pdf file.
Previously, we distributed with .AppImage file, but we were fascinated by the features of pi-apps and decided to distribute using pi-apps.
We are going to use pi-apps in the future...

The description needs some work. The first line is the tooltip - a message that appears when hove3ring the mouse over the app name. Right now the tooltip would be the website URL, which is unhelpful. Also the description should do more than tell the user how to run it, it should explain who might need this app and what it is used for, in simple terms. For some reason many people struggle to write a good description, and I would be happy to help, but I still have no grasp on what this actually does or what to use it for.

Look to other app descriptions for inspiration.

Also somehow you have both a install and install-64 scrip[t. My guess is that if this app is 64bit-only, you just need to remove the install script. Easy fix.

CHESSCOIN 0.32% is a Hard Fork (2019) by Chesscoin (2016) and was made to keep -save -get and appled (who wrote the code of chesscoin is unknown... Satoshi Nakamoto wrote the code for Bitcoin and maybe so wrote the code for Chesscoin?)
