Short answer

The impulse to scroll at night is hardest to resist in exactly the moment when a manually-triggered app blocker fails. LockHour Pro solves this with a schedulable Sleep Wind Down: set a nightly start time and the OS DeviceActivity system activates the block automatically, even if you've forgotten to open the app. The default duration is 60 minutes targeting Social, Video, and Entertainment categories; you can swap in any specific apps or domains. The block ends at a configurable time (default 7 AM) and lifts automatically — no morning steps needed.

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

  • Sleep Wind Down: 60-minute default lock on Social, Video, and Entertainment categories
  • Schedulable via iOS DeviceActivity — triggers automatically every night without opening the app
  • Hard Mode: cooldown delay + typed confirmation phrase required to cancel the session early
  • Calls, alarms, messages, and non-selected apps remain fully accessible throughout
  • Configurable end time (default 7 AM); everything unlocks automatically

FAQ

Does the sleep schedule work even if LockHour is not running in the background?

Yes. The schedule is registered with iOS DeviceActivity — the operating system handles triggering it. LockHour does not need to be running in the foreground for the block to activate.

Can I block specific apps for Sleep Wind Down rather than categories?

Yes — the selection uses Apple's FamilyActivityPicker, so you can choose specific apps (e.g. TikTok, Reddit) plus any web domains in addition to or instead of broad categories.

What if I genuinely need to use a blocked app at night?

Without Hard Mode enabled you can end the session immediately in the app. With Hard Mode on, there is a cooldown delay plus a typed confirmation phrase before cancellation — enough friction to interrupt an impulse scroll, but not a parental lock. Someone sufficiently determined can also revoke Screen Time authorization in iOS Settings.
