An iPhone app blocker with focus sessions, a Lock Mode and whitelists.
Checked 11 November 2026 against UNIKWORK SYSTEMS LLP's own pages. We make moss, so we have linked every source below.
What Regain is
Regain: Screen Time Control is an iPhone app blocker with focus sessions, an optional Lock Mode and whitelists that keep essential apps open. It is a subscription: the App Store lists Weekly at $2.99, Monthly at $6.99 and Yearly at $39.99. It needs iOS 18 or later. Several unrelated apps share the Regain name, so check the maker before you install.
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.
