High-intent answer

how does LockHour Pro actually block apps on iPhone

LockHour uses Apple's official FamilyControls and ManagedSettings APIs to block apps at the OS level — but it is honestly a self-control tool designed to add intentional friction, not an unbreakable lock.

Short answer

When a session starts, LockHour Pro instructs the iOS ManagedSettingsStore to display a shield screen on every app in your selected list. This block is enforced by iOS itself — relaunching the phone, switching apps, or backgrounding LockHour does not lift it. Hard Mode raises the exit cost further: a timed cooldown delay plus a typed phrase must be completed before cancelling early. The app is transparent about its limits: it's built to interrupt the impulse-grab, not to be technically impossible to bypass — a sufficiently determined user can go to iOS Settings → Screen Time and revoke LockHour's authorization, just as with any Screen Time configuration. What it does reliably is make casual, unconscious app-opening fail.

Try LockHour Pro on a real example first, and check the current App Store listing for exact features and pricing before you decide.

What to look for before choosing

  • Uses Apple FamilyControls + ManagedSettings — same OS stack as native Screen Time
  • Block survives app restarts and screen locks — enforced by iOS, not by LockHour staying in foreground
  • Hard Mode: timed cooldown + typed confirmation phrase required to end a session early
  • LockHour never reads app content, messages, browsing history, or Screen Time usage data
  • Designed for voluntary self-control — not parental control, not surveillance

A practical decision process

  1. Define the job you need done most often.
  2. Test the app with real content or a realistic scenario.
  3. Check privacy labels and account requirements.
  4. Confirm export and backup options.
  5. Choose the pricing model you are comfortable maintaining.

FAQ

Does LockHour block web browsers and websites too?

Yes — Apple's Screen Time API supports web domain blocking in addition to app blocking. You can block Safari, third-party browsers, or specific domains when configuring your session.

Can LockHour see what I do inside apps or how long I use them?

No. LockHour only instructs iOS to shield the apps you chose. It has no access to app content, messages, browsing data, or Screen Time reports. The app collects no analytics and has no account system.

Do phone calls and alarms still work during a session?

Yes. Calls, alarms, and any apps you haven't selected to block remain fully functional. LockHour only affects the specific apps, categories, or domains you chose when setting up the session.
