This is a good alternative app to use with CaRPM OBD2 reader if you don't like theires, it also supports more active PiDs at a time.
Reviews for Piston – OBD2 Car Scanner
One of the few working with all BT dongles and without tons of useless options and ads. Good job.
Even there are 3 permanent errors on dashboard, your app doesn't read them. Not worthy.
Sometimes it doesn't wanna link up, but other than that the numbers are the most accurate compared to other apps I've previously used.
Worked great for saving me a trip to the repair shop! I thought it was faulty O2 sensors, all reading good, turns out it was a dead EGR valve, no voltage. 2007 Ford F150 6cyl manual trans, still going strong.
Great! Very simple and clear UI. Only OBDII reader app that works well and doesn't look like it is 6+ years old!
Most often tasks are connect Bluetooth, load faults, clear faults. Would it be possible to make these steps a widget, only requiring one click to do all three?
Very nice and clear UI, I just wish I could log the real time data being displayed too. If that is or was possible, it would be the complete package.
Excellent so far for FREE! Found this ap when the "torque ap" I used with my veepeak Bluetooth scanner stopped being free. Piston is actually SO good with its data charts I think it's WORTH buying!
Good app for quick info from a Bluetooth ODB2 reader. Interface is a little clunky at times and doesn't display all the info that other apps might. Overall, I'm happy with it.
