What are the best apps to limit screen time, and do they work?

We are wary of “best app” lists, including this one. Most are ranked by who pays for placement. So here is an even-handed version: what the built-in tools do, what a few well-known third-party apps say they do on their own pages, and what the research says about whether any of it works. No affiliate links, no rankings, nothing paid.

What is the best free app to limit screen time?

Two, and both are already on your phone: iPhone Screen Time and Android Digital Wellbeing. Both phone makers now build serious screen time tools in, and for most adults they are enough. The caveat is that built-in tools are easy to override, because you hold the passcode.

iPhone Screen Time. On current iPhones running iOS 27, Screen Time shows how long you spend in apps and websites, with a weekly report covering your most used apps, how often you pick the phone up, and how many notifications you received. You can set Time Allowances for categories such as Entertainment, Games or Social Media, and Screen Time Schedules for when apps are available, for example weekday windows for work, dinner and evening. An Always Allowed list keeps chosen contacts and apps reachable at all times.^[1] Older versions of iOS offer similar controls under the names Downtime and App Limits.

Android Digital Wellbeing. Google’s version gives you a dashboard of screen time, unlocks and notifications. App timers set a daily limit per app; when time runs out, “the app closes and its icon dims”. Bedtime mode can turn the screen to greyscale on a schedule, and Focus mode lets you pause distracting apps temporarily. You can also set a PIN on app limits.^[2] Exact features vary a little by phone maker.

If you have never opened either, that is the first job. Just seeing the weekly numbers is useful. Our guide on how to use your phone less has a gentle way to start.

What is the best app to manage kids’ screen time?

Two, depending on the device: Apple’s Screen Time with Family Sharing, or Google Family Link. On iPhone and iPad, it is Screen Time run through Family Sharing. Apple’s parental controls let you set time allowances and schedules, choose which apps and websites are allowed, manage who your child can contact, set age ratings, and use Ask to Buy for purchases. Apple’s instruction is to set the child’s Screen Time passcode on your own device, not the child’s.^[1]

On Android phones and Chromebooks, Google’s option is Family Link. It can set daily screen time limits, individual app time limits, downtime and school time, require approval for new apps, and show your child’s location.^[3] The caveat: Family Link can only partially supervise a child signed in on an iPhone or in a web browser, so it is not a cross-platform answer.^[3]

Neither tool decides how much is right for your child. That is a family decision, and our page on screen time for kids by age sets out what the official guidance actually says.

What are the best anti-doomscrolling apps?

Four are well known: one sec, Freedom, Opal and ScreenZen, though there are dozens. We have described them using only what each developer’s own website says, checked on 28 September 2026.^[5] Features and prices change often, so check before you commit.

• one sec. Adds a pause before a chosen app opens, with a prompt and the option to close it instead. Available on iOS, Android and as a browser extension. The developer says the essentials are free, with paid extras.
• Freedom. Blocks apps, websites or the whole internet, and syncs a blocking session across devices. It lists macOS, Windows, iOS, Android, Chromebook and Linux. There is a free version and a paid premium plan with a free trial.
• Opal. Lets you block chosen apps on phone or desktop on a schedule or timer, with a paid Pro tier that adds a “Hard Mode” you cannot switch off. It has a free tier.
• ScreenZen. Blocks apps and websites, sets time limits, can limit how many times a day you open an app, and shows prompts before unlocking. It describes itself as “completely free”, supported by optional donations.

The difference between these and the built-in tools is mostly friction. Built-in limits are a wall you can step round with one tap. Most third-party blockers try to make the step round slower, more deliberate or, in some cases, impossible for a set time.

Do screen time apps actually work?

Yes, modestly: 57% fewer app openings in one 2023 study, with real caveats. The best evidence is about friction. In a 2023 study in PNAS, researchers collected six weeks of data from 280 people using one sec, which interrupts an app with a short pause and the option to back out. On average, participants closed the app 36% of the times it interrupted them. Over six weeks they also tried to open their target apps 37% less than in the first week. Combined, actual openings fell by 57%.^[4] A second experiment with 500 people found the option to dismiss mattered most; the reflective message on its own was not effective.^[4]

The caveats are important. The participants chose to install the app, so they were motivated. Results were compared with their own first week rather than with a separate control group. And one of the three authors is the app’s developer. It is a genuine peer-reviewed finding, and it is also exactly the kind of result worth reading with care.

What it does suggest is useful beyond any one app: a small pause and an easy way out can interrupt a habit that runs on autopilot.

Do you need an app at all?

No, not always, because the environment does more than any app. A phone that charges in the kitchen overnight is not in the bedroom at midnight, whatever the settings say. A phone in a drawer during dinner does not need a timer. Apps work on the moment of temptation; the room works before temptation arrives.

Some changes that cost nothing:

• Move the charger out of the bedroom.
• Delete the worst app from the phone and use it on a computer, if at all.
• Turn off non-essential notifications. Both built-in tools show you how many you get.
• Set a greyscale evening. Android’s Bedtime mode can do it on a schedule.
• Give the hands something else. A book by the sofa, a pack of cards on the table.

Our guide on how to stop doomscrolling goes further into this. Tools help. Where the phone lives, and what else is within reach, helps more.
