Review summary

Piston is widely praised for ease of use, a clean UI, and solid Bluetooth OBD-II compatibility. It delivers codes and sensor data with charts and offers good value via a one-time purchase. Users note it’s effective for diagnosing issues and often saves trips to the shop. Common requests include customizable dashboards, importing custom PIDs, reordering live data, Android Auto support, and occasional licensing prompts, with some vehicle-specific limits (e.g., Renault voltage readings). Overall, a strong, no-subscription OBD2 app.

Strong Bluetooth OBD-II compatibility (works well with Veepeak and other BT adapters)
Provides codes and sensor data with informative charts
Good value: useful features with a one-time purchase instead of a subscription
Helpful for diagnosing issues and saving trips to the repair shop

2026-02-11	Jo*****	Very easy to use and super useful when diagnosing issues. I have two suggestions on making it better. 1) I have two Bluetooth scanners that work with Piston. Each one stays with a different car. I can switch back and forth between them, but the names are something along the lines of "ELM II" vs "ELMII" and I cannot remember which car has a space in the name. Some customization options would be nice in this regard. 2) I would like to combine charts with colored lines, or set up groups.

2025-09-18	ps*****	Missing the ability to import custom PIDs and a customizable Dashboard. Also can not reorder PIDs in Live Data and in-app fault code information is non existent. Bought premium anyway to support development, hoping app would improve in the near future.
