Simple, Fast, And Useful. This app does exactly what I need it to do. It may not be as in depth as other apps, but it works very well. The interface is easy to use. Works well with "Generic Bluetooth OBD2 interfaces". It retrieves and clears codes faster than other apps (torque) IMO. There is even enough to get you started with basic troubleshooting (Fuel trims, AFR, etc..)
No Gimmicks , But a practical Basic Scantool If you just want to read and reset fault codes this is the app for U. It connects real fast and tells U the Obd2 fault codes. But there is not much on diagnostics. But then the app is free and you do not even have to pay for an expansive adapter.
Good app. Thanks a lot for support! Connected well to my wifi iobd on andriod. Read all errors I wanted to see. I recommend to move Settings button to left floating menu. My respect to developer.
1st app that worked with cheapo 327 Bluetooth! I tried 10 or more apps and got *nowhere* with my 2005 Cary. With 'Piston' I am able to read everything *and* was able to reset my 'Check Engine' light! Yay!!
Piston connects every time. The interface does exactly what I want it to do. It will tell me things about my car that I never thought to ask. Consistently reliable. Easy to use.
Fantastic APP!! If you dont get a VIN or some other data, please understand that not all cars provide everything such as VIN. especially on EU or UK vehicles. This is not the apps fault! Keep up the good work dev!
- Improvements for some adapters with the ELM chip in version 2.1.
