I figured it out. When you open the app, there's a shortcut for the GPS, Bluetooth, and other, on a toolbar above it. It saves you from going back and forth through the phone settings to start the process. The free version is manual input, only. Other than changing the starting odometer if needed, everything works automatically. When you're done, you unplug it from the truck and it ends. You still need to click the GPS and Bluetooth off from the toolbar. If you want a report for the day, monthly or whatever, you click on "reports" and have it email a completed spreadsheet with everything recorded and totaled, to you or your tax people. It also keeps track of tolls, oil changes, maintenance purchases, fuel, and other stuff I'm too lazy to likely to forget bothering to write. Sounds similar to what Scott uses without having a separate GPS???
