An iPhone blocker where you talk to an AI coach to unlock your apps.
Checked 11 November 2026 against Razzed, LLC's own pages. We make moss, so we have linked every source below.
What Superhappy is
Superhappy Screen Time Blocker is an iPhone app that puts an AI coach between you and your apps. You set sessions by time of day and daily limits. To unlock an app you have a conversation with the coach, which then gives you a time limit and locks you out when it is up. It is a subscription. The App Store lists Pro Monthly at $14.99 and $19.99, and Pro Annual at prices from $49.99 to $99.99, so check the price in the app. It needs iOS 16 or later.
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.
