Night shift moves your schedule,
not your clock.
It reads your real roster, works out where your clock actually is, and tells you when to sleep — and when you're too tired to be driving.

A straight run of nights can be shifted, and there's published science for how. A mixed week can't — trying moves your worst hour to 7am, exactly when you're on the road.
Placed against your clock rather than the one on the wall — in the dark, and at the same hour every day of the run, because a window that moves nightly is one your body never learns.
So you arrive at handover rested instead of already sixteen hours awake.
Sunrise on the drive home is the biggest unwanted clock signal in a night worker's week. Blocking it is free, and it works.
On a straight run it keeps your hours where they are, because the run is not over until it is over. Where the roster allows it, it plans the way back to a day schedule for your family instead of leaving you to endure one.
With the hours-awake number attached. Not a vibe.
Type a pattern, tap the days, pick the calendar it is already in, connect the feed your employer publishes, or photograph the unit sheet. Press and hold a day to give it its own hours.
Every item carries the reason underneath it. An instruction you do not understand is one you will not follow twice.
The moment the job actually hurts people. Named, with the number attached.
Point the camera at the printed roster and pick your row. It is read on your phone, and only your own shifts leave it — never the photo, never anyone else's name.
When a run of shifts ends: how you slept against what the plan asked, the naps you took, how it compares with the block before, and one cheap thing to change. Observations, never a score.
A private link to your rest times for the week, for a partner or a housemate. Never your shift hours. Off whenever you turn it off, and gone after 90 days.
A countdown to your next sleep on the lock screen and as a Live Activity on iPhone; on Android, a silent countdown in your notifications during a shift, and a home-screen widget on both. The clock times stay hidden while the phone is locked.
If you allow it, the app reads how long Apple Health recorded you in daylight and shows it beside the plan's advice to get outside. It stays on your phone and never changes the plan.
Every timing in this app is worthless if the phone stays quiet. So the wake-up is not a notification — it is the operating system's own alarm, set locally on your phone.
One app and one plan. The mechanism underneath is whichever one the phone will not quietly drop.
A Time Sensitive notification breaks through Focus and not the ringer switch — and a phone on silent overnight is what a sleeping person has. The alarm is the one thing that gets past it.
It is held by the system, not by us, so it survives the app being swiped away, the phone being restarted, and the battery saver that stops everything else.
On an older phone, or if you say no to the permission, the wake-up falls back to a notification — one that gets past Focus but not silent mode. The app tells you that, on the screen, rather than letting you find out by oversleeping.
The app also reports which alarms it believes fired and which it missed, because on this one we would otherwise never know.
Six places a night-shift week usually goes wrong — and what happens here instead.

The model behind it is accurate to about an hour in laboratory studies that measured the light people saw. We estimate yours from your roster, which is less precise. Good enough to place a nap and a pair of sunglasses. Not good enough to state a precise body-clock time — and we never will.
The spread in light sensitivity between one person and the next. It is why the estimate is a window rather than a time — and why day one says so, instead of implying a precision it has not earned.
Are hostile to human physiology, and no app changes that. It can only get you the best sleep available inside the one you were given.
Apps in this category claim they handle any schedule.
This one tells you when it can't.
