Comments on ProMasters Only for Android

★★★★★ R.A. LaFleur · Nov 7, 2025

If you own a Prom aster you need this app. Easy to use. Easy to see gauges that monitor everything including the most important transmission oil temp. The 2.0 version is even better than the original. Stop being a cheap b*****d and buy this app.

★★★★★ James Emch · Jun 3, 2025

Currently doing a cross-country trip using the app watching my transmission, coolant, and oil gauges. Loving it

★★☆☆☆ Dean Child · Dec 3, 2025

Love Kip! V1 App worked with DA100 dongle until App got updated. Now all I get is a warning (that can't be turned off) for high oil pressure. No gauge readings at all. The App has some SERIOUS drawbacks: 1) Need to be able to arrange/customize gauge display; 2) Need to be able to set customizable high/low alarm thresholds for engine temp, tranny temp, and voltage; 3) Once an alarm is "acknowledged", Need to be able to "ignore" or "continue monitoring" until next engine start/shutdown cycle.
