Named ‘Paced,’ Lavoie’s app works by having users select three apps that they want to use less, and then the app gives them 30 minutes of screen time. Once the allotted time is up, a pop-up appears, locking you out of the app for an hour and nudging you to take a break.

Paced users can reduce the hour lockout by three minutes for every 100 steps they walk. This could be especially useful on a nice Saturday, encouraging users to go for a walk, or if you have a workspace you can walk around in.

For now, Paced is available only on Android, mainly due to Lavoie’s familiarity with the platform. But she does say that an iOS version is coming soon for the iPhone users out there.
