No problem with android dude! Check out this example. I log in to my brave browser. Then I use the (install app) option located in the options, and it installs a shortcut just like an app on the phone's desktop. And secondly, for more comfortable use, I have synchronized it with blue wallet and I can do all my operations from the wallet interface for greater convenience. And it works perfectly 💯

There's going to be mobile app to which you can connect your Hub.

For now you can use Alby Extension in Firefox on mobile
