Where did you found that application?
Hi.
Thank you for your interest.
It's a website with added widgets from coinmarketcap.
Hopefully, that will be reliable to use.
I'll certainly do my best.
I will install it anytime if this project will be proven and tested by lots of people.
No need to install anything. You may wish to add a shortcut to your homescreen/browser so you can access the site in one click, when you need to check the data.
