How to make Do Not Disturb follow your shift roster

Why the normal bedtime schedule doesn't work

Every phone has a way to switch Do Not Disturb on at a set time: "every night 22:30 to 06:30", or "weekdays only". That's fine on a Monday-to-Friday job. On shifts it fails in three ways:

• The days move. A schedule repeats by weekday, but a roster doesn't. On a 4-on, 4-off or a Panama or DuPont rotation, your nights land on different weekdays every cycle.
• The times move. After nights you sleep in the morning, before earlies you sleep early in the evening, and on days off you sleep at night. One schedule can't hold all three.
• You can't afford to be unreachable. Plenty of shift workers get called in or rung about a shift swap. Muting everything is worse than leaving the phone alone.

So the question isn't how to turn Do Not Disturb on. It's how to tie it to the roster instead of the calendar week.

Four ways to do it on Android

1. Turn it on by hand

The quick settings tile works, and costs nothing. The trouble is the moment you need it: you get home after a night shift, exhausted, and the step most likely to be forgotten is the one between you and a phone call at 11:00. If you go this way, make it part of the same wind-down every time. The sleep routine guide covers building one.

2. A calendar-event rule

On Pixel phones and many others close to stock Android, Do Not Disturb (called Modes on newer versions) can be scheduled to run during events in a calendar, instead of at fixed times. You choose which calendar it watches. The menus vary between phones and Android versions, but it sits under Settings, then Sound or Modes, then Do Not Disturb schedules.

The catch is that it runs while an event is happening. If your calendar only holds your shifts, you'll get a quiet phone at work, not in bed. For sleep, you need a separate calendar of sleep blocks, kept up to date every time the roster changes. That's workable on a fixed rotation you can copy forward, and a chore on a roster that comes out month by month.

Samsung's Modes and Routines doesn't have a calendar-event trigger, so on a Galaxy phone this option isn't there.

3. An automation app

Automation apps such as MacroDroid and Tasker can switch Do Not Disturb on and off on almost any trigger, calendar events included. They work on Samsung phones too. They're powerful, but you're building the logic yourself: which calendar, which events, how the times are worked out, and what happens when a shift is swapped. You also need the sleep blocks to be somewhere the app can read, which usually means the same calendar chore as option 2.

4. An app that reads the roster: Shifty Habits' Sleep Mode

This is the one I built for it. Shifty Habits already knows your roster, whether that's a repeating cycle or a roster you enter as you get it, so it can work out the sleep windows itself:

• Give each shift type a sleep window, once. For an early, "wake up an hour before it starts, after eight hours' sleep". For a night, "go to sleep an hour after it ends". For days off, a bedtime.
• It follows the roster from then on. Every night shift on the calendar gets its morning sleep, every early its early night, weeks ahead. Swap a shift or change its hours and the windows move with it.
• Shifts come first. If a sleep window would run into your next shift, it's cut short so Do Not Disturb is never still on when you need to be up.
• It runs without the app open. Do Not Disturb comes on and goes off by itself, including after the phone restarts. Open the app now and then so it can plan further ahead.

For the nights that don't follow the plan, there's a Sleep now button, which stops by itself before your next shift, and a habit reminder can carry the same button, so "go to bed" can be one tap from the notification.

Still getting the call from work

Whichever method you use, how you set up the exceptions matters more than how Do Not Disturb gets switched on. A sensible setup for shift work:

• Calls from starred contacts only. Star your workplace's numbers, your manager and anyone at home who might need you. Everyone else can wait until you're up.
• Repeat callers on. Anyone who rings twice within 15 minutes gets through. Someone with something urgent will call twice, and a sales call won't.
• Alarms always on. You shouldn't be able to sleep through the alarm for your next shift.
• Messages and other notifications quiet. Group chats are the main thing waking up day sleepers.

Sleep Mode offers exactly these choices: calls from anyone, contacts, starred contacts or nobody, repeat callers on or off, and alarms always ringing. It can also set your ringer, notification and media volumes for sleep and put them back afterwards. It uses a Do Not Disturb mode of its own, so your normal Do Not Disturb settings aren't touched, and on Android 15 and later it shows in the system's Modes list under the app's name.

Android does the call filtering itself. Shifty Habits never reads your contacts or your call history; the privacy policy has the detail.

What about an iPhone?

Shifty Habits is Android only. On an iPhone, a Sleep or Do Not Disturb Focus with a time schedule has the same weekday problem, so the closest you'll get is turning it on by hand or with a Shortcuts automation.
