Just One Thing: App Blocker
Screen Time and Focus Control
Free · In‑App Purchases
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.
WHAT YOU GET
• One task at a time — free-form, anything you want
• System-level app blocking via iOS Screen Time — no workarounds
• Streak tracking — consecutive completed sessions
• Total focus time — cumulative across all completed sessions
• Lock screen and home screen widgets — task name and streak, always visible
SUBSCRIPTION
Just One Thing requires a Pro subscription to use. A free trial is included — no charge until the trial ends. Subscriptions auto-renew unless cancelled at least 24 hours before the end of the current period. Manage or cancel anytime in your Apple ID settings.
