Apple Watch · watchOS 11+
Your watch keeps ending your set.
Sweat, sleeves, the bench, the bar. Something brushes the screen mid-rep and your workout is paused, your timer is gone, or you're staring at the watch face. LiftLock replaces all of it with a locked screen that has nothing on it to press.
Four taps a session. That's the whole product.
Open
On the watch. Your phone can stay in your bag, or at home.
Lock
Two deliberate taps, then a short countdown to get set.
Train
Elapsed time and nothing else. Taps and swipes do nothing at all.
Unlock
Hold the screen for two and a half seconds. Or ask Siri.
No buttons. No scrolling. Nothing to hit.
There is no pause control on this screen, and no end-session control, because there is no way to add one that a barbell can't find. A touch is measured, not obeyed: anything shorter than a full two-and-a-half-second hold does nothing whatsoever.
The Digital Crown is ignored entirely unless you switch crown unlock on. watchOS Double Tap is turned off for this screen. Lower your wrist, take the set, raise it again — the clock is still running and still correct.
What it locks, and what no app can lock.
Plenty of apps in this category imply they can switch your watch off. None of them can, and neither can this one. Here is the actual line.
What LiftLock controls
- Removes every control from the workout screen — nothing to pause or end by accident.
- Ignores taps and swipes. No scroll view, so there is nothing to move.
- Switches off the Double Tap gesture while you're locked.
- Optionally turns on Apple's Water Lock, which kills the touchscreen outright.
- Keeps the session running through screen sleep, a force quit, or a restart.
What Apple doesn't allow
- Disable the Digital Crown. Pressing it always returns you to the watch face.
- Disable the Side Button, or the power and emergency screen behind it.
- Block Control Center or Notification Center.
- Stop you leaving the app. You can always get out.
- Listen for a wake word. LiftLock never opens the microphone.
These are platform rules that apply to every third-party app on the watch. Your session stays locked underneath all of them — come back and the clock is still running.
When you want the glass genuinely dead.
Maximum turns on Water Lock, Apple's own feature for swimming. The touchscreen stops registering anything at all until you rotate the Digital Crown to release it — the same gesture you'd use getting out of a pool.
Apple only permits this during a workout session, so choosing Maximum starts one and asks for a single Health permission the first time. LiftLock doesn't read your heart rate, doesn't save a workout to Health, and doesn't upload anything anywhere. Decline the prompt and it locks at Standard instead and tells you why.
Before you ask.
Can I get stuck in a locked session?
No. Press-and-hold can't be switched off — the settings screen won't let you disable every unlock method at once, and it won't let Siri be the only one, because Siri needs a network and a room quiet enough to hear you. There is always a way out that works with a dead phone in a loud gym.
Does it need my iPhone?
No. Locking, the timer and unlocking all run on the watch. Leave your phone in a locker or at home. The iPhone app is for setup, help and an optional account — it's never in the way.
What happens if the app crashes mid-session?
The session comes back. The lock state and the start time are written to disk, and elapsed time is always recalculated from that timestamp rather than counted up — so a force quit, a screen sleep or a restart doesn't lose a second. An unlock gesture that was half-finished is discarded, not completed.
Do I need an account?
No, and you never will for the lock itself. Signing in with Apple, Google or an email address is optional and only syncs your settings and profile picture between devices. You can delete that account from inside the app whenever you want.
What does it do to my battery?
Standard protection costs almost nothing — the screen redraws once a second and there's no networking, no GPS and no sensor use. Maximum runs a workout session to satisfy Apple's Water Lock rule, so it uses roughly what any workout app does.
Which watches does it run on?
Apple Watch Series 7 and later on watchOS 11 or newer. Double Tap is only switched off on hardware that supports it; everything else works across the range.
