★★★★★Jonathan Shipp· Nov 19, 2025
Grate application for live data/freeze-frame information. Used thoroughly on voltage and throttle position/engine load. Love the app (PRO) edition for diagnostic work on 2004 R53 Mini Cooper S. LOVE IT GREAT APP.
★★★★★Rick Schumacker· Dec 28, 2025
Used many years ago RAM 2500 Cummins diesel and loved all this could do
★★★★☆Saiful Islam· Nov 8, 2025
ABS system code is not detectable and failed to monitor pressure sensor data.
★★★★☆Robert Reffitt· Mar 18, 2026
You have to update the premium for it to be a good value but once you do great little machine only gave four stars because it doesn't do much without the buying premium
★☆☆☆☆Danny Blanck· Nov 23, 2025
Loved this app in the beginning. Was looking for a scanner app that had misfire counters for each cylinder while diagnosing a misfire. Had to pay $5 a month for premium to get misfire counters, which was okay. I paid to get upgrades, but they only worked for a week after paying for premium. In the app, it wants me to subscribe again to get the upgrades I should already have. No, my subscription hasn't expired yet. It was a monthly fee and has not been a month yet. Do not recommend this app!!
