Get key OnStar safety services that give you help in a crash, assistance when you have car trouble and much more — right on your smartphone.

Your download of the OnStar Guardian app does more than offer added peace of mind. We’ll donate $1 to the Alzheimer's Association (up to $225,000) for every download.

OnStar Safety & Security Members receive the OnStar Guardian app as part of their plan. If you don’t own a GM vehicle, you can try it for 30 days, and after that, it is only $15 a month.

Plus, you can share these benefits with up to 7 loved ones at no additional cost.


Mobile Crash Response
Help in a crash — even if you or your loved ones can’t ask for it. The Guardian app is designed to use your smartphone’s sensors to detect a crash and alert an Emergency-Certified Advisor for help.

Roadside Assistance
Your loved ones can get a tow, a battery charge, help with a flat tire or have their doors unlocked. They can even get fuel if they run out of gas.

Emergency Services
The red Emergency button gives your family access to an Emergency-Certified Advisor 24/7. They can assess the situation and contact 911. With Google Assistant™ enabled, you can also connect to emergency help with simple voice commands such as “Hey Google, call help using OnStar Guardian.”

Location Status
Save and share locations with loved ones — even get notifications when they leave for or arrive at their destination — so you’ll know when they get there safely.
