Beta testing

Beta testing

The purpose of the beta is to test the app in a variety of conditions. So you are required to drive the car on a regular basis and connect the app to it. Some bugs may happen on the app side. In that case, the user should provide feedback describing the conditions as accurately as possible. There is an option in the app to upload to the cloud a debug file to help the developer to root cause the problem. This file is uploaded only if the user decide to do so.


  • iOS device running iOS 9 or higher
  • WiFi OBD2 dongle
  • A Volt, Ampera, Holden Gen 1 or Gen 2. Other models are not supported

Beta registration

To register for the beta program follow the below steps:

  • Send an email to mygreenvolt.beta at gmail dot com using the email address you wish to use to get access to the beta server
  • Indicate in the email:
  • iOS device model
  • iOS version
  • Volt model year


Those are some of the few screeshots of the app and a video


OBD2 adapter

Every recent car comes with a diagnostic port located on the driver side. In order for the application running on your smartphone to get data through this port, an OBD2 adapter is used. Those adapters can be found online and their price range from $15 to $100. The more expensive versions include better power management, high reliability and proprietary GM SW-CAN protocol. The app only support WiFi adapter for now.

If you plan to use you adapter on a daily basis, which is recommended to keep track of your statistics, I would advise to use an OBDLink MX or any other good reputation brand.

Using a cheap adapter is a hit or miss. Out of the two Veepeak adapters I tested, one has been working ok for the past year whereas the other triggerde the engine light couple of times.

Once you get your adapter, plug it in and follow the walk-through pages of the app to configure it. The adapter must be properly configure for your device to connect to the adapter over WiFi and still use cellular netword to upload data to the Cloud.
