Nice to see what network I'm on sometimes, but I still wish the code input process was easier. Trying one brings up the phone dialer with a blank field; then it's a matter of pasting the code that the app copied into the clipboard. Needs an update too, since Sprint still shows up as an option. Overall this is a really useful app sometimes!

Jerrod, please send me an email at, there are a few different reasons the dialer might not be working for you and I would love to help get it fixed.

This app has been great over the years as a Fi user, and I've found it a little easier to use than some of the others I've tried. I'd love to see a few more details about the connection strength in the app, tho, and it would be nice if it showed info about the Pixel series' Dual Connect capability. Also, unfortunately, I'm not sure how much longer it's useful without 5G support or now that Sprint has been fully merged into T-Mobile and I'm not switching between networks any more...
