If you’re a good student and tired of eating Ramen noodles, Pocket Points is for you. All you have to do is open their app and keep your phone locked while you’re in class and you’ll earn points that you can redeem for discounts at local businesses.

While there are a number of apps for making making money, most of them require you to actually do something. That’s not the case with Pocket Points, where you can earn points for NOT using your phone.

The less you use your phone, the more points you earn. How’s that for passive income?

The concept is pretty simple. As a “Pocket Pointer” you’ll earn one point for every 20 minutes you keep your phone locked in class. Then, you can redeem your points for a variety of discounts at local businesses in the Pocket Points Gift Store.

For example, at Penn State you can use 10 points (just over 3 hours phone-free) to get a 10% discount on PSU-branded gear at the university bookstore.

So far, the app is only available for students 18 and over at Penn State in Pennsylvania and Chico State in California, but with recent coverage on popular websites like The Verge, Kotaku, Product Hunt, and even TIME, Pocket Points is sure to be available at your school soon.

In case you’re thinking about gaming the system and trying to earn points while you chill at the bar, don’t bother. The app uses GPS to make sure you are where you say.
