Final pre-trip report.
Once the Bluetooth adapter is turned on the app syncs within 30 seconds.
I really like that I get tire psi, tire temperature, & tire sensor battery level readings in a single glance before it moves on to the next tire.
I prefer/keep my 2 rolling tires at 62 psi and the spare at 65 psi. *This is a semi-local trip so leaving the 2nd spare (50 psi) at home which rides in the truck bed. Since it's staying home I disabled the TV section so that the app doesn't keep searching for that spare tire.
I removed a sensor from the valve stem and a nice loud & clear audible warning sounded as well as vibration and status bar warnings.
I have put the app icon on my home screen. Once we return from our trip I'll remove it from my home screen until the next trip.
