What services are included with the OnStar Guardian app?

The Guardian app provides key OnStar safety services right on your smartphone, including:

Mobile Crash Response

The Guardian app is designed to use your smartphone’s sensors to detect a crash and alert an Emergency-Certified Advisor. The Advisor will call your phone and contact First Responders and provide them with your location. For Android™ users, the app can automatically connect — even if you can’t reach your phone.

Roadside Assistance

If your family needs to travel, have added confidence knowing that someone is ready to help. You and your loved ones can get help with a flat tire or battery charge or have their doors unlocked. They can even get fuel if they run out of gas.

Emergency Services

The red Emergency button in the app provides access to OnStar Emergency-Certified advisors, who are available 24/7. These advisors are certified by the International Academies of Emergency Dispatch and can assess a situation, contact 911 as needed, provide critical medical instruction and stay on the line until help arrives.

Location Status

OnStar members and the loved ones they choose can share their location with the entire group in the “My Family” section of the app. Members can have added peace of mind and see locations of their loved ones, based on the location of their smartphone, right in the app. View and share locations with each person you add to your plan — right in the app. Get a little peace of mind knowing where those closest to you are — even when you’re apart.

The app also lets you invite up to seven loved ones to the “My Family” group. Everyone gets the safety services within the app as well as Location Status, which includes:

  • Viewing one another on a live map
  • Real-time location updates
  • Ability to share location
  • Cellphone battery life status

How does the OnStar Guardian app work?

By using the sensors in your smartphone, including the accelerometer, the app can detect when you are in a moving vehicle. When a crash is detected on an Android device, the app can automatically connect you with an OnStar Emergency-Certified Advisor, who can contact First Responders and your Emergency Contact. When a crash is detected on an Apple® device, the app alerts an OnStar Emergency-Certified Advisor, who will then call your smartphone, requiring someone in the vehicle to answer the call. Advisors can also contact First Responders and your Emergency Contact.

Enabling location permissions within the app allow an OnStar Advisor to identify your smartphone’s location and contact First Responders for help, even if you can’t ask for it.
