How it works
One rule: keep it shut.
-
Name it
Pick the one thing.
Write what you're working on and choose 25 or 50 minutes.
-
Seal it
Close it, or turn it over.
The seal presses in with a click you can feel. The screen shows the time left and when you'll be back.
-
Hold it
Opened early? 10 seconds.
Your phone counts them down like a heartbeat. Put it back and the seal holds.
-
Keep it
Seal kept.
Every seal you keep fills in a day. Breaks are honest: you see how far you got.
The catch
Open it early,
and the seal breaks.
That's the whole trick. Not another timer you swipe away: closing the phone is the start button, and opening it is a choice you feel in your hand.

Made for iPhone Duo
Your phone has a lid now.
- The hinge is the button. Close it to seal. Open it to break.
- Two pages inside. Every screen is laid out like a book on the inner display.
- The outer screen keeps time. Minutes left and when you'll be back, at a glance.
- Every other iPhone works too. Lay it face down and the same rules apply.

The Ledger
A year of focus, at a glance.
Only kept seals count. See every month as a calendar, your longest streak, your average seal and the hours you focus best.
Details
Strict where it matters.
Kind where it should be.
Calls still ring
Answering a call never breaks a seal. When it ends, you get 10 seconds to close up again.
Two passes a week
Need your phone? A pass gives you 3 minutes with it open, and the seal stays whole. New passes every Monday.
Feels alive
Sounds and haptics for every moment: the press, the warning, the break, the finish.
On your Lock Screen
Live Activity, Dynamic Island, widgets, a Control Center button and Siri. Start a seal without hunting for the app.
Private by design
No account, no ads, no tracking. Your sessions never leave your iPhone.
Breaks built in
After a kept seal, take a short break. A soft bell tells you when it's time to go again.
