Just One Thing: App Blocker

One task. Your apps are blocked until it's done. Just One Thing is a commitment device. Pick the one thing you need to finish. Choose which apps to block. Start. Your selected apps lock — and they don't come back until you mark it done. No AI cameras. No photo verification. No judgment. Just a hard block that works. HOW IT WORKS Set your task — anything, in your own words. Choose which apps to block. Start your session. Your apps lock via iOS Screen Time. When you're done, mark it done. Apps unlock immediately. That's it. WHAT MAKES IT DIFFERENT Most focus apps ask you to be disciplined. Just One Thing removes the option not to be. Your apps are blocked at the system level — not by a timer you can dismiss, not by a reminder you can ignore. No curated task lists. No AI verification. No passive nudges. Just one thing, blocked until it's done.
