The OnStar Guardian app, which is intended for use in vehicles only, uses sensors in your smartphone to determine if the smartphone is in a moving vehicle before it begins scanning to detect a crash event.

The in-vehicle Automatic Crash Response is available in any properly-equipped GM vehicle, while the OnStar Guardian app extends this service to any vehicle you drive, ride in or share.
Mobile Crash Response services are intended for use in vehicles only and can connect to an Advisor automatically on Android devices only. Service availability, features and functionality may vary by device and software.
