Locked in · 6:00:00

You wandered off for 1 sec. I stopped the clock, so none of it counted.

Locked In
A focus app for iPhone and Mac

The focus timer that stops when you wander off.

Studying, deep work, writing, practice: set your hours and lock in. Leave to scroll and Latch stops the clock, and it stays stopped until you come back and tap resume.

This little demo follows the same rule as the app. Hold the button to lock in, then switch to another tab and watch the clock stop.

6:00:00

a 6 hour goal

Normal timers keep counting while you scroll.

And you're scrolling right now.

A normal timer

1:12:00

Still counting. Says you worked the whole time.

Locked In

1:12:00

Stopped the second you left.

You set six hours. You checked one thing. Forty minutes later, a normal timer says you've been working the whole time. Locked In only counts the time you actually stayed.

One rule, three screens.

Locked in

Hold to lock in. The clock starts.

Pick your hours, then press and hold. Latch snaps shut and counts down while you stay in the app.

Paused

Wander off and the clock stops.

Switch to another app and Latch pops open. A nudge calls you back within seconds, and the time you were gone never counts.

Done for today

Only you can press resume.

Nothing restarts by itself. Come back, tap resume, and keep going until the hours you promised yourself are real.

The done screen: a beaming Latch with sparkles and 6 hours locked in

Latch finds you mid-scroll.

Ten seconds after you leave, Latch taps you on the shoulder. Then again at two minutes, and at ten. The moment you're back, the nudges stop. The clock doesn't restart until you tap resume.

On your Mac too

In your pocket and on your desk.

Locked In is a native app, not a website. On iPhone it pauses the moment you swipe away. On Mac it sits on your screen like a desk clock and pauses when you click into something else.

iCloud sync

One chain on every device.

Lock in on your Mac in the morning and your iPhone at night. It all adds up to the same day, the same week and the same chain.

  • Your hours and your chain

    Every device's focus time counts toward today.

  • Your presets

    Save a set-up once and start it anywhere.

  • Latch's look

    The hat you earned shows up everywhere.

  • No account

    It uses your own iCloud. There's nothing to sign up for and we never see it.

Timer faces

Five ways to watch the clock.

Swipe the timer or tap the arrows to change face, even in the middle of a session. The clock never skips a second.

  • The Flip clock face: split-flap cards for hours, minutes and seconds

More than a countdown.

Your week

See where the hours went.

Tap your chain on the home screen to open your week: every day's focus, how often you wandered off, and the time that didn't count.

  • One link in the chain for every day you finish a session
  • Miss a day and the chain rests. Miss two and it starts again
  • A recap after each session shows exactly how it went
Your week: 26 hours 12 minutes locked in, a bar for each day, and a 9 day chain
Focus and steps

Say what you're locking in on.

Give the session a name and break it into steps. Tick them off as you go, and add another one mid-session when the work grows.

  • Save a set-up as a preset and start it with one tap
  • Rhythm splits long sessions into focus rounds with breaks built in
  • Hard mode: no breaks, no extra time, and a ten second hold to quit

Hats and colours unlock as your chain and your hours grow. Nothing to buy. The only way in is doing the work.

  • Party hat at a 3 day chain, a crown at 30
  • Mint at 10 hours, bubblegum at 50
  • Latch wears it everywhere, including your Lock Screen

Everything else that keeps you there.

Your hours are nobody else's business.

No account, no analytics, no ads. Your sessions are saved on your phone or Mac, and kept in step between your own devices through your iCloud. We never see any of it. Read the privacy policy.

Questions

What happens when I leave the app?

The clock stops at that moment. When you come back you'll see how long you were gone, and the timer stays frozen until you tap resume.

Do I need an account?

No. There's no sign-up, no ads and no tracking. Your sessions live on your device, and if you use iCloud they stay in step across your own devices. We never see them.

Is app blocking required?

No, it's off by default. The timer works fully without it. If you turn it on, iOS asks for Screen Time permission and you choose which apps to shield.

Where are my stats?

Tap the chain at the top of the home screen. It opens your week, with each day's focus, how often you wandered off and your longest chain.

How do I change the timer face?

Swipe the timer left or right, or tap the arrows above it. You can switch in the middle of a session without losing a second.

Can I type my own duration?

Yes. Tap the time to type anything from 5 minutes to 12 hours, or use the stepper and the quick buttons.

Six hours.
