The Snapshot app is available to Progressive customers in select states who were offered and enrolled in the mobile version of Snapshot (not the plug-in device) when they purchased their policy.

Here's how it works: the app uses the technology on your phone to help you tailor your driving. It measures your driving data, like hard braking and mileage, and gives you personalized tips on how to improve. All you have to do is keep your phone with you as you drive – the app runs in the background, so you can just set it and forget it.
