excellent

Br***** 2026-11-07

As someone who travels between several areas during a shift, having to manually change radio channels can be a bit tedious. An option to automatically switch channels based on location would be useful. Overall, the app is good, and the push to talk feature works well. The main screen could do with a bit of a tidy up, though, as it's quite crowded and some buttons can easily be pressed by mistake. Plenty of potential.
