The OnStar Guardian App

Now for anyone in any vehicle

Key OnStar safety services on your smartphone

OnStar® is a name that has stood for safety for 25 years. With the OnStar Guardian™ app, you and your family can take that trust and experience on your phones anywhere you go.

OnStar Safety & Security Members now have OnStar Guardian as part of their plan. Don’t own a GM vehicle? You can try it for 30 days, and after that, it is only $15 a month — and you can share it with 7 loved ones at no additional charge.

Your download of the OnStar Guardian app does more than offer peace of mind for you and your family. We donate $1*132 to the Alzheimer’s Association for every download to help advance Alzheimer’s care, support and research.
