This is a development-signed build, so Android will show a warning that the app is from an unknown source. That is expected. Upgrades install over the top of your existing copy, keeping your sign-in and saved list.
What it does
Shows your assigned jobs straight away, even with no signal, then quietly updates in the background.
Groups by priority, then appointment date, then distance.
Real driving distance and arrival time, not straight-line.
One tap to mark a job On route or Arrived on site.
Customer name and phone number, pulled from the ticket.
Opens the ticket, directions and media uploads without leaving the app.
Tolls
Google Maps ignores the no-tolls request when it is opened from another app, so switch it on once in Google Maps → Settings → Navigation → Route options → Avoid toll roads. After that every route avoids tolls.
