What BB (Burnout Buddy) is
BB, also known as Burnout Buddy, is an iPhone and iPad blocker built around "schemas": blocks that run indefinitely, on a schedule, after a usage limit, or when a Shortcut fires, including by location or Focus mode. Its Strict Mode stops you editing or deleting a schema while it is active and blocks uninstalling apps. The app is free. The App Store lists a single Burnout Buddy Pro purchase at $9.99 and optional tips, with no subscription. Its last update was version 1.3.2 in April 2025.
What moss is
moss is an iPhone app that comes with a small physical stone. You choose the apps that distract you, tap your phone on the stone, and those apps stay locked until you tap the stone again. People who live together can link their phones to share schedules and put their phones down at the same time, while each person keeps control of their own phone. Locking is free in the app, the stone is a one-time purchase, and the household features are a paid add-on.
