What Brick is
Brick is a $59 magnetic puck and a free app. You choose apps, tap your phone on the Brick to block them, and tap again to unblock. It has up to 10 modes, schedules and a Strict Mode, and it works on iPhone (iOS 18 or later) and Android (12 or later). It is the product that made this category, and its app is rated 4.9 on the App Store from roughly 60,000 ratings.
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.
