Post Nights: Shift Sleep

Post Nights plans your sleep around your real roster — and wakes you at the end of every sleep window. Built for nurses on rotating nights. Night shifts move your schedule, not your body clock. Post Nights reads your roster, estimates where your body clock actually is, and places each sleep window against that clock rather than the one on the wall — in the dark, and at the same hour on every day of a run. WHAT IT TELLS YOU • When to sleep after a shift, and for how long. • When to nap, so you arrive at handover rested instead of already sixteen hours awake. • When to put sunglasses on. Sunrise on the drive home is the biggest unwanted clock signal in a night worker's week. • When to seek light, and when to avoid it. • On days off, whether to hold your night hours or plan the way back to days. • Before the drive home, how many hours you will have been awake — information, not a verdict. Every instruction carries its reason underneath it. AN ALARM THAT GOES OFF On iOS 26 and later, the wake-up is a system alarm. It sounds through silent mode and Focus, and it survives the app being closed and the iPhone restarting. On earlier versions of iOS it falls back to a Time Sensitive notification, which gets past Focus but not the ringer switch — and the app tells you so on the screen. YOUR ROSTER, IN ONE SCREEN Type your pattern, tap the days, pick your calendar, or connect the feed your employer publishes. Or photograph the unit sheet: it is read on your iPhone, and only your own shifts leave it. Press and hold a day to give it its own hours. With a connected feed, changes are picked up for you and your plan and alarms follow them. AFTER EACH BLOCK When a run of shifts ends: how you slept against the plan, the naps you took, the block before beside it, and one cheap thing to change. Your own numbers, never a score. SHARE YOUR WEEK A private link that shows a partner your rest times for the week, never your shift hours. It ends after 90 days, or when you turn it off. ON THE LOCK SCREEN A countdown to your next sleep as a Live Activity and in widgets, clock times hidden when locked. WITH APPLE HEALTH If you wear an Apple Watch, Post Nights can read your time in daylight from Apple Health and show it beside the plan's advice to get outside after you wake. It is read on your iPhone and never sent anywhere, and you can turn it off at any time. THE HONEST PART The body-clock estimate is based on published circadian research — the Forger–Jewett–Kronauer model of the human circadian pacemaker — and its model 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. That is enough to place a nap and a pair of sunglasses. It is never enough to state a precise body-clock time, and we never will. Some rosters are hard on human physiology whatever you do; Post Nights plans the best sleep available inside the one you were given, and says so when it cannot. YOUR DATA A roster says when you are home and asleep, so it is treated as sensitive. A connected feed link is stored encrypted. Nothing is sold, nothing is shared with advertisers, and nothing is reported to your employer. You can export everything, or delete your account, from inside the app. SUBSCRIPTION Try it free first, then choose a yearly or monthly subscription. Payment is charged to your Apple ID at confirmation of purchase. The subscription renews automatically unless it is cancelled at least 24 hours before the end of the current period, and you can manage or cancel it in your App Store account settings. Deleting the app does not cancel it. Terms: https://postnights.com/terms Privacy: https://postnights.com/privacy Post Nights is not a medical device.
