Ratings and reviews

Agreed with someone else, so much data for free. Thanks so much for the app. BTW, I can confirm that it doesn't work with VEEPEAK OBDCheck BLE+ Plus. It works fine with an ELM 327 mini.

Doesn't work with BLE adapter as the BLE adapter does not pair through Bluetooth settings, and Voltage app does not allow selecting BLE device in app if it is not already paired. It DOES connect with the Torque Pro app even without this pairing step, so I know it is capable of connecting to phone if proper protocol is used. OBD2 port device: LeLink BLE OBD2 diagnostic tool. Car: Chevy Volt 2013.

This app has already surpassed MyGreenVolt (no longer maintained) in graphics and clarity of the information provided, and is quickly catching up to Opel Ampera E Pro in quantity of useful information provided. This has become my defacto app for logging data from my 2013 Volt.

What's new

Fix for 2011 Volt and ELM v1.5
