Yes! I think an official app would be great!
Google honestly sucks when I’m on my forums and trying to do other things, it just is a NIGHTMARE
But, there is like an “unofficial” app that works decently on phones (not sure about iPhones but def for Androids) Basically all you have to do is:
Log In to your Forum account through your phone
Go to the 3 dotted button at the upper right corner
In the options, there should be a button that says, Add to Home Screen
And then it should load and you can find it with all your other apps!
