Earning points currently varies depending on what kind of phone you’re using. We’re working on an update that will make Android able to earn off campus.
Below image, left screen is Campus Mode, right is Goal Mode:
If you leave your phone locked for longer than your goal, you will earn bonus points at a reduced rate.
If something goes wrong and you don't get your points, just tap the green contact button on the bottom right of this screen and let us know!
For now, you must be on campus in an academic building to earn points on Android. Just lock your phone with Pocket Points open and you will automatically start earning.
