A Computer Timer for Kids: Six Free Methods, With Pros and Cons

There are six free ways to set a timer on your child's computer: a kitchen timer, a phone alarm, the shutdown command, Windows Task Scheduler, the built-in Windows screen time limits and the Antidrot app. The first two only give a signal. The command and Task Scheduler turn the computer off along with any unsaved game. Family Safety locks access based on a limit. Antidrot shows a window on top of the game and alternates play with breaks without cutting the game off. Below is how each method works and where its weak spots are.

Why a Child Needs a Timer

Time runs differently in a game: half an hour flies by like ten minutes, and your child is genuinely surprised that it's “already time.” A timer does two jobs. It makes time visible, and it takes the parent out of the enforcer role: it isn't a parent asking to stop, it's a signal everyone agreed on in advance. There's no point arguing with an alarm, so there are fewer conflicts.

A good timer should do four things: warn in advance, be impossible to miss, not destroy unsaved progress, and work the same way every day. None of the methods below is perfect on every count, which is why they're often combined.

But a timer only works together with an agreement. Discuss in advance how long your child can play, what to do if a match is still going, and what happens if the signal is ignored.

1. A Kitchen Timer or a Sand Timer

This is the simplest option. A mechanical timer or a large sand timer sits next to the monitor: your child can see how much time is left and sets the timer at the start of the game. For preschoolers and younger school-age children, it's also a hands-on lesson in what “half an hour” looks like.

Pros: free, visual, no computer needed. Cons: the ring is easy to miss with headphones on, the timer can be “forgotten,” and it doesn't remind anyone about breaks within play time.

2. A Phone Alarm or a Smart Speaker

A parent's phone or a smart speaker is handy because the signal doesn't come from your child's desk, so it's harder to switch off quietly. A good trick is two signals: a warning ten minutes before the end, so your child has time to finish the round and save, and then the main one.

Set a repeating alarm for the days your child plays, and give it a clear label, such as “Time to save.” A teenager can be asked to set the alarm on their own phone: that way they learn to take responsibility for their own time.

Pros: free, can be set to repeat on specific days of the week. Cons: the signal can't be heard through headphones, and the parent has to remember the alarm every time.

3. The shutdown Command: the Computer Turns Itself Off

Windows has a built-in command for a delayed shutdown. Press Win+R, type shutdown -s -t 3600 and press Enter. The number after -t is the delay in seconds: 1800 is half an hour, 3600 is an hour, 5400 is an hour and a half. Windows will show a notification that the computer will shut down soon.

The timer can be canceled with the shutdown -a command. Any school-age kid finds this out quickly, so the command works more like an agreement than a lock.

Pros: built into Windows, nothing to download. Cons: unsaved progress is lost, it's easy to cancel, and it has to be started by hand every time.

4. Task Scheduler: Shutdown on a Schedule

If you want the computer to shut down at the same time every evening, Windows Task Scheduler will do the job. Item names may differ slightly between versions, but the steps are as follows:

1. Open Task Scheduler by searching for it in the Start menu.
2. Create a basic task and give it a clear name, such as “Bedtime.”
3. Choose to run it daily and set the time.
4. For the action, choose to start a program: the program is shutdown, the arguments are -s -t 600. This gives your child ten minutes to save.
5. Check that the task runs while your child is using the computer under their own account.

Create the task under an administrator account, and give your child a regular account without administrator rights; otherwise the task can simply be deleted. Shutting down an hour before bed is especially useful: to find out why late-night gaming makes it harder to fall asleep, read our article on gaming before bed.

Pros: works every day without a parent's involvement. Cons: the same as the shutdown command, plus a more complicated setup; the timer is tied to the clock, not to how long your child has already played.

5. Screen Time in Windows

The built-in Windows parental controls work through Microsoft Family Safety. The parent sets a daily limit and hours of access, and when time is up, Windows locks access to the computer; your child can ask for more time, which a parent has to approve. You'll need Microsoft accounts for both the parent and the child, and the internet. There's a detailed walkthrough in our guide to Windows 11 parental controls.

Pros: free, reliable, includes reports. Cons: the game is cut off the moment the limit ends, setup is needed, and the system doesn't build breaks into the day on its own.

6. Antidrot: a Play and Break Timer on Top of the Game

Antidrot is a free app for Windows 10 (1703 or later) and Windows 11: set up by an installer from a USB flash drive, with no internet required. It shows a small window in the center of the screen, on top of all windows, including fullscreen games. It's impossible to miss even with headphones on, yet it doesn't take focus or block input: your child pauses the game, saves and exits on their own.

The time is set by an access key, for example 3600.600.14400.C8FCE983: an hour of play, a ten-minute break, up to four hours in total. During play time the window is hidden. During a break it shows a “Time left until unlock” countdown, and after the break your child presses “Continue.” When the total limit is used up, the window stays on screen until a new key is entered. The parent gets the key in the key generator or in the Telegram bot, and our Antidrot presets by age will help you pick the right amount of time.

If your child has stepped away from the computer and hasn't pressed “Continue,” their play time isn't wasted, although the total limit keeps counting. There's no visible “Close” button in the window: it appears only after the master key is entered, and the app shows the master key to the parent just once, at first launch. An honest limitation: the process can be ended in Task Manager, so it's a reminder, not a lock.

Which Timer to Choose

Start with one method and watch how it works for a week: does your child hear the signal, do they have time to save, have the arguments become more frequent? If it isn't working, move on to the next option rather than making the punishments harsher.

The methods are easy to combine: Task Scheduler turns the computer off before bed, and during the day Antidrot reminds your child to take breaks. For an overview of every option, including agreements and launcher settings, see our guide on how to limit your child's gaming time on a PC.
