Risks of downtimeDon’t make these mistakes when enabling it.Downtime is Screen Time’s quiet hours: a stretch of the day when most apps step aside. It is one of the best tools Apple gives you, and also the easiest to set up in a way that either does nothing or gets in your way at the worst moment. These are the mistakes worth avoiding before you lock it.Which names you will see. On iOS 27 and macOS 27, Downtime is part of Screen Time Schedule: you set time windows and choose which app categories each window allows. On iOS 26 and earlier it is Downtime, with a start and an end time. Most mistakes below apply to both. The first one, Block at Downtime, and the five-minute reminder belong to iOS 26 and macOS 26 and earlier. On iOS 27, what keeps the schedule in place is the passcode.1. Leaving Block at Downtime offOn iOS 26 and macOS 26 and earlier, Downtime has a switch called Block at Downtime. With it off, you see a reminder that it is downtime and can carry on with the app. With it on, the apps can’t be opened: on iPhone they appear dimmed with an hourglass. The switch only appears once a Screen Time passcode is set.That is the second half of this mistake. Without a passcode, you can switch Downtime off again in a few taps, and a single Turn Off App & Website Activity ends Downtime, App Limits and Always Allowed together. A passcode you never learned is what makes the schedule hold.The two halves need an order, because once the passcode is set, turning on the switch asks for it. Set the passcode with Detox behind a short first lock that opens later the same day. When it opens:

Go to Screen Time, then Downtime.

When it asks for the passcode, Detox walks you through typing it with a keypad video, so you still never see the digits.

Turn on Block at Downtime, then tap Lock again in Detox.

2. Forgetting what you need at nightDuring downtime, only calls, messages and the apps you allow stay available. Walk through an ordinary evening and the next morning, and add what you would really miss to Always Allowed:

Maps, if you drive or walk home late

Your authenticator and banking apps, so a sign-in code or a payment never has to wait until morning

Tickets, transit and parking apps

Health apps and anything you rely on for care. Apple suggests the Health app and family members as examples.

Then do the opposite: take out anything on the list that you only open to pass the time. Always Allowed is exactly the part that downtime leaves alone.3. Not checking who can reach youCalls and messages follow your communication settings. If downtime allows only specific contacts, a call or message from anyone else won’t go through while downtime lasts. Make sure family, and anyone who may need you urgently, are on that list before you lock it.4. Picking a schedule you can’t keepA schedule that starts at 21:00 on the night you always work late will be fought every week. Give different days different times: Customize Days on iOS 26, or a schedule per group of days on iOS 27. Start a little later than feels heroic. You can move it earlier once it holds.On iOS 26 and earlier, a scheduled downtime sends a reminder five minutes before it starts. Treat it as your cue to finish up, not as a countdown to beat.5. Forgetting your other devicesWith Share Across Devices on, your schedule applies to your iPhone, iPad and Mac on the same Apple Account. That is good news for a phone habit, and a surprise if your Mac goes quiet halfway through an evening of work. With it off, each device keeps its own settings, and the device you didn’t lock becomes the way around the one you did. Decide which you want before the passcode goes in.6. Locking it for weeks on the first tryRun the schedule for a night or two behind a short Detox lock that opens the next morning, and notice every time it got in the way for a good reason. Fix those, then lock it for longer. A schedule you trust is one you leave alone.Digital Detox keeps your Screen Time passcode locked until the time you pick. It runs in your browser and needs JavaScript turned on.
