How to Block Apps on Your Phone and Laptop at the Same Time (2026 Guide)

You finally block Instagram on your laptop, sit down to work, and your hand drifts to your phone without you even deciding to. The block did its job on one screen and quietly handed the distraction to the other. This is the single biggest flaw in how most people try to focus: they block one device at a time, and attention simply flows to whatever screen is still open.

The fix is to stop thinking in devices and start thinking in sessions. Below is exactly how to block the same apps on your phone and your computer at once, which tools can actually do it, and how to set it up in a couple of minutes.

Why blocking apps on just one device doesn't work

Single-device blocking fails because of device-hopping. You block social media on your work laptop, so your brain, looking for the next easy hit of novelty, reaches for the nearest unblocked screen instead. The phone in your pocket is almost always that screen.

And the cost of each little hop is far higher than it feels. Research by Gloria Mark at UC Irvine found it takes about 23 minutes to fully return to a task after an interruption. A five-second glance at a notification is never five seconds; it is five seconds plus the long climb back into focus. When the average person already spends close to six to seven hours a day on screens, a blocker that only covers half of them is leaving the door wide open.

The fastest way: use a cross-device app blocker

A cross-device app blocker holds a single block list across every device you sign in on. Start a session on your laptop and the same apps lock on your phone at the same instant, so there is no second screen to escape to.

What 'cross-device' actually means

Plenty of apps say they work on phones and computers. Far fewer truly sync one session across both at the same time. That distinction is everything. A desktop-only blocker leaves your phone open; a phone-only blocker leaves your laptop open. What you want is one account, one block list, and one button that locks every screen together.

Cross-device app blockers compared

The honest takeaway: if you live entirely inside Apple's ecosystem, Screen Time and Opal can cover you. If you have an iPhone and a Windows laptop, or an Android phone and a Mac, you need a dedicated cross-device blocker, because the native tools do not talk to each other across platforms.

How to block apps on your phone and laptop, step by step

The flow is the same across every good cross-device blocker:

1. 1Install the app on every device you want covered, your phone and your computer at minimum.
2. 2Sign in to the same account on each one. This is what links the devices into a single session.
3. 3Build one block list. Add the apps and the matching websites that pull you away most: social, news, video, games, shopping.
4. 4Start a session, or schedule a recurring one (for example, weekdays 9am to 12pm).
5. 5When the session starts, the block applies to every signed-in device at once. There is no other screen to drift to.

That fourth step, scheduling, is where focus stops being a daily act of willpower and becomes the default. More on that below.

How to block specific apps like Instagram, TikTok, and YouTube everywhere at once

To block a specific app on every device, add both the app and its website to your block list. This matters more than people expect: block the Instagram app and your brain happily opens instagram.com in a browser instead. Cover both and the loophole closes.

A good starting block list for most people:

• Instagram, TikTok and YouTube (the big three for time-loss), plus their websites.
• X/Twitter, Reddit and Facebook, app and web.
• News apps and any game that you open 'just for a minute.'
• Shopping apps if late-night browsing is your thing.

Make it stick: strict mode and scheduling

A blocker you can switch off in two taps is a suggestion, not a block. The two features that turn it into a real commitment are strict mode and scheduling.

Strict mode (Focus calls it Lock Mode) stops you from ending a session early or removing apps from the list until the timer runs out. It is the difference between deciding once at the start, when you are motivated, and re-deciding every time you feel the itch. If you tend to talk yourself out of focus mid-session, this is the setting that matters most.

Scheduling auto-starts your blocks on a recurring basis so you never have to remember. Set focus windows around your real routine, deep-work mornings, study afternoons, a wind-down block before bed, and the tool enforces them without a daily decision.

What about free and built-in tools?

The native tools are genuinely useful and worth knowing, as long as you understand their ceiling:

• Apple Screen Time blocks apps and websites across your Apple devices and is free, but it does nothing for a Windows or Android device.
• Microsoft Family Safety covers Windows, Xbox and Edge, but not your iPhone's apps.
• Google Family Link manages Android well, but stops at the edge of Google's ecosystem.

Block apps with friends or your whole team

Willpower is a finite battery; accountability is a renewable one. Blocking apps alongside other people, sometimes called body doubling, makes focus dramatically easier because you are no longer relying on yourself alone.

This is what Focus Huddles are for: start a shared session with a friend, a study partner, or your whole team, and everyone locks in together. For remote teams it turns 'focus time' from a calendar event everyone ignores into something real and shared.

The bottom line

Blocking apps on one device just moves the problem to the other. The only reliable fix is a cross-device blocker that locks your phone and laptop in the same session, ideally with a strict mode so you cannot wriggle out and a schedule so you do not have to think about it. Set the block list once, turn on Lock Mode, and let one session cover every screen.
