Jeanie Boehm's review of Teletrac Navman
Last winter when my rig died on I-5 and Teletrac Navman popped up a dropping battery voltage alert before the dash even blinked, I called a nearby shop and avoided a tow. I had Samsara before and that thing would lag or show stale dots, but Teletrac actually gave me live volts and a fault code - saved me a day's pay as an owner-operator in the PNW. Setup was pretty quick and the app just tells you the one thing you need, simple and actually useful, no jok.
