How to Make Android Warn Your Child Before Screen Time Ends

The episode is still running. The tablet goes dark. And you’re the one standing there, so you’re the one who did it.

If you’ve gone looking for a setting that gives your kid a heads-up before the screen cuts out, you’ve probably found a lot of articles telling you to give a two-minute warning yourself, and very few telling you which Android setting makes the device do it. This page is the second thing.

I went through Google’s help documentation, Samsung’s, Xiaomi’s and Huawei’s, plus the help pages of several third-party apps, and checked what each one actually claims. Some of what I found is a gap rather than a feature, and I’ve said so where that’s the case.

The thirty-second version

  1. Google Family Link does warn. Google’s help page says your child gets a notification when their device is about to be locked. It does not say how far in advance, and there’s no setting to change it.
  2. Android’s built-in App timers don’t warn at all. Google’s own documentation says the app closes and its icon dims. Nothing about a countdown.
  3. “Screen time reminders” sounds like the answer and isn’t. It’s a newer Digital Wellbeing feature that nudges you after a long stretch inside an app. It isn’t tied to your limit, and Google describes the reminders as occasional.
  4. Manufacturer skins mostly ship Google’s tools. Samsung’s parental controls hand you over to Family Link. Xiaomi keeps everything under Digital wellbeing & parent controls and documents no warning at all. Huawei’s Digital Balance is Huawei’s own, and its documentation only describes a prompt after the time is up.
  5. If you need a specific, published interval, it’s third-party apps that publish one — a warning every minute over the last 5, or 10 and 5, or a single 5-minute warning, depending on which one you pick.

This is the default answer for most families, and it’s better than its reputation on this specific point.

To set a daily limit (Google’s instructions):

  1. Open the Family Link app
  2. Top left, select your child
  3. Bottom left, tap Screen time
  4. Tap Time limits
  5. Turn on Daily limit
  6. Tap Weekly schedule, pick a day, and enter the limit
  7. Tap Apply to all days of the week → Done

Google says time limits work on Android 7 and up, and that system apps can’t be limited.

The warning. On the same page, Google lists two moments when the child is notified: once when you first set up screen time for them (Android only), and again when their device is about to be locked. That’s it. That’s the whole description. There’s no stated interval, no way to configure it, and no mention of it anywhere in the settings.

I want to be plain about this rather than fill the gap with a guess: I could not find any Google documentation that states how many minutes of warning the child gets. Plenty of third-party blogs assert a number. None of them cite Google. If you’re planning around a specific interval, don’t plan around Family Link’s.

Bonus time. Google’s page also describes bonus time, which lets you grant extra minutes for the day without changing the underlying limit. Useful to know it exists, because a locked device with no escape hatch is how you end up unlocking the whole limit at 7pm and never putting it back.

Family Link also does per-app limits (instructions here):

  1. Open Family Link → select your child
  2. Screen time → Time limits → App limits
  3. Pick the app → Set limit → choose hours and minutes → Done

Requirements listed: Android 7.0 and up, or Chrome OS 83 and up. Limits apply across all your child’s Android and Chrome OS devices. System apps are excluded.

That page says nothing at all about a warning before an app limit is reached, or about what the child sees when it is. If there’s a countdown here, Google hasn’t documented it.

Downtime and School time: also no documented warning

The schedules page covers Screen time → Schedules → Downtime / School time, and describes what happens during the scheduled block. It doesn’t mention any alert before the block starts.

Can the child see their own remaining time?

Partly, and only recently. Google’s page on Digital Wellbeing for supervised accounts says a child can check app limits and bedtime settings, but only through the Parental controls screen, and that supervised accounts need Android 15 or higher for it. The path on the child’s device is Settings → Digital Wellbeing & parental controls → Parental controls → App activity → Go to Digital Wellbeing.

So on Android 15+, a kid old enough to navigate Settings can look up their own limits. That’s not the same as a glanceable countdown, and it’s a fair distance from what an eight-year-old will actually do mid-episode.

Android’s own App timers: no warning, and easy to undo

If you don’t want a supervised Google account at all, Digital Wellbeing has app timers built into the phone.

Path (Google’s Android help):

  1. Settings → Digital Wellbeing & parental controls
  2. Tap App timers
  3. Tap Set timer next to the app
  4. Choose the limit → OK

What happens at zero: Google’s wording is that the app closes and its icon dims. Timers reset at midnight. There is no mention on either the Android or Pixel help page of any notification before that happens.

Two more things worth knowing before you rely on this:

  • Whoever is holding the phone can delete the timer. Google’s Pixel page says so directly: delete a timer to use the app again before the midnight reset. There’s no PIN on it. It’s a self-control tool that happens to also work on a very young child.
  • It’s per-app, not per-device. Three video apps means three timers, each with its own budget.

”Screen time reminders” is a different feature than you’d hope

Around November 2024, Google started rolling out a Digital Wellbeing feature called Screen time reminders, which shows a small pill-shaped popup near the top of the screen after you’ve been in an app for a while. 9to5Google and Android Authority both covered the rollout, which reached Pixel plus several other Android makers.

Path: Settings → Digital Wellbeing & parental controls → Screen time reminders → Use reminders, then pick which apps it applies to.

Here’s why it isn’t the answer to this article’s question. Per 9to5Google’s account, the feature is off by default, Google describes the reminders as occasional, and there’s no control over how often they appear — the only per-app control is switching them off. Reporters saw one fire after 25 minutes in Instagram and after 15 minutes in another app. It’s a nudge about time spent, not a countdown to time remaining, and it doesn’t know anything about the limit you set.

Also worth flagging: I couldn’t find this feature described on Google’s own help pages. Everything above comes from press coverage of the rollout, not documentation.

What the manufacturers actually ship

Samsung

Samsung’s parental controls are Google’s. Samsung’s own support page walks you to Settings → Digital Wellbeing and parental controls → Parental controls → Let’s do this, and describes this as connecting you to Google’s Family Link app. It requires One UI 2.0 or later. Which means the Family Link answer above is the Samsung answer, warning included, interval still unpublished.

Samsung’s Digital Wellbeing page covers app timers under Settings → Digital Wellbeing and parental controls → App timers and doesn’t mention any advance warning either.

Samsung Kids is separate. From the Samsung Kids home screen, tap More options (⋮) → Parental controls → enter your PIN, then use Screen time to set a daily playtime schedule. Samsung’s page doesn’t describe any warning or countdown shown to the child before playtime ends.

Xiaomi (HyperOS / MIUI)

Xiaomi keeps all of this under Settings → Digital wellbeing & parent controls. Xiaomi’s support article gives that path and, honestly, not much else — it’s a location and a screenshot. App limits live inside it. Nothing on that page mentions a warning before a limit is reached.

Huawei

Huawei’s is its own system, called Digital Balance, which matters because Huawei phones released after the 2019 entity-list decision ship without Google’s services outside China. (Models released before that still shipped with them, and Honor, sold off at the end of 2020, has them too.)

Path: Settings → Digital balance, enable screen time management, then set the available screen time for work days and rest days separately under Screen time, plus app limits and away time. App limits sit under Settings → Digital balance → App limits, where each app can be set to Always allowed, Never allowed, or Limit use.

I checked Huawei’s own tutorial for an advance warning and didn’t find one. What it does describe is a prompt after the time is up, with an option to request more time. That’s the opposite end of the transition from what you’re looking for.

One qualifier: the child can pull down the notification shade and see Time left. But that takes the child deciding to look, which isn’t the same as the device interrupting them — and the second thing is what this article is after.

Everyone else

I didn’t verify OPPO, vivo, OnePlus, Honor, or Motorola, so I’m not going to tell you what they do. 9to5Google’s rollout coverage mentions OnePlus, Oppo and Nothing among the devices getting Screen time reminders, which suggests they’re running fairly close to stock Digital Wellbeing, but that’s an inference and you should treat it as one. If you’re on one of those, the path to check first is Settings → Digital Wellbeing & parental controls.

Third-party apps that publish an actual interval

This is where you find numbers, because it’s a feature these companies compete on. Each of these comes from the vendor’s own help or product page — I haven’t independently tested any of them, and vendor claims are vendor claims.

AppWhat the vendor saysNotes
QustodioOn Android: a notice every minute, starting 5 minutes before the limit, until the device locksTheir help page splits this by platform, and this is the Android (plus Chromebook and Kindle) line; iOS gets 15 and 5 minutes, Windows/Mac 5 and 3. The notice does not appear for time-schedule restrictions.
BoomerangTheir documentation states 10-minute and 5-minute notifications on the child’s device before the daily limit ends (no platform scope given)Also describes a home-screen widget so the child can see their own time and usage. Boomerang also ships on iOS, and this page doesn’t distinguish.
Screen Time (Screen Time Labs)A 5-minute warning shown on the child’s screenIt’s a checkbox under Settings → Daily Limit in the app on the child’s device, not in the parent app. Their page notes Apple devices didn’t have it at the time of writing.
KidsloxNotifications when the child is close to the daily limitNo interval published, and no configuration described
FamilyTimeNothing described in their published materialTheir screen-time feature page describes blocking windows but no advance warning. Note that this is an absence of evidence, not a vendor statement that the feature doesn’t exist. Included as an honest counterexample.

The free workaround, and one uncomfortable finding

If none of the above fits, there’s a zero-cost version: set a timer on the phone’s clock app, or a kitchen timer, for a few minutes before the limit.

But before you do that as the solution, there’s a study you should know about, because it points the other way. Researchers at the University of Washington ran interviews with 27 families and a two-week diary study with 28 more, children aged 1 to 5, and found that kids given a two-minute warning by a parent were more upset when the screen went away, not less. The same work found that natural stopping points in the content — end of the episode, end of the level — made transitions easier. I wrote that up in full in why the two-minute warning backfires, including the researchers’ own open question about whether a warning delivered by the technology itself, rather than by a parent, might work better.

Nobody has answered that question with a study, as far as I can find. But it’s the reason “which setting makes the device do it” is a more interesting question than it looks, and the reason a kitchen timer you announce is not the same intervention as a notification the phone produces on its own.

One more caveat from the same body of research: those findings are about preschoolers. If your child is nine, none of it transfers automatically.

What I’d actually do

  • Already using Family Link? You have a warning. You just don’t get to know or set the interval. Combine it with bonus time so the ending has an escape hatch you control, and don’t promise your child “you’ll get five minutes’ notice” — you can’t guarantee that.
  • Not using a supervised account, and the child is young? Digital Wellbeing app timers are the fastest thing to set up and give no warning whatsoever. Know that going in.
  • The warning is the whole point for you? Then it’s a third-party app, and the table above is sorted by how specific the vendor is willing to be. Specificity is a decent proxy for whether the feature actually exists.
  • Try the stopping point before the countdown. Ending on the credits costs nothing and has better evidence behind it than any warning interval on this page.

If the anger is the part you’re really trying to solve, rather than the mechanics, there’s a separate piece on why some kids explode when the tablet goes off and when it’s worth calling someone.

Written by a parent who builds Tortoise Time, an Android screen-time app for kids aged 6 to 14. It nudges quietly at 60%, 75%, and 90% of the daily limit before blocking anything at 100%. It’s free, with no ads and no in-app purchases. Your child’s screen-time data stays on the phone by default — the only things that leave the device are anonymous crash reports and usage statistics, as our privacy policy says.
