I just ordered the one you recommended, thanks Jos.Any ANSI B40.1, mine is grade B which is 2% accuracy.
Looks like this one (I do not have this exact model), you can take it on road trips.
Amazon.com: TireTek Flexi-Pro Tire Pressure Gauge, Heavy Duty Best For Car & Motorcycle - 60 PSI: Automotive
Sure it is not connected to your phone, but it gives an accurate reading.
I know I can't connect it to my phone but I can "calibrate" my FOBO after the TireTek, and use it when working on the bike. ;-)
