How to Block Instagram, TikTok and YouTube on Every Device (2026)
To block Instagram, TikTok and YouTube on every device, use a cross-device blocker that syncs one session across your phone and computer, then add both the apps and their websites to the block list. Blocking only the app leaves the browser version open, and blocking only one device just sends you to the other. Cover both apps and sites on every device at once.
Instagram, TikTok and YouTube are engineered to be hard to put down, and they follow you everywhere: phone, laptop, tablet, even your TV. That is exactly why blocking them is trickier than it looks. Block the TikTok app and you open tiktok.com in a browser. Block them on your laptop and you reach for your phone. To actually win, you have to close both loopholes at once: every app and its website, on every device, in a single session.
This guide gives you the method first, then exact numbered steps, then the per-app gotchas for Instagram, TikTok and YouTube specifically. If you want the deeper background on why one-device blocking fails, see blocking apps on your phone and laptop at the same time.
The method: block the app and the website, on every device
There are two loopholes that quietly defeat most blocking attempts. Close both and these apps lose their grip.
- The website loophole. Instagram, TikTok and YouTube all have full websites. Block only the app and your browser becomes the new front door. You must block the app and the matching site.
- The device loophole. Block them on your laptop only and your attention hops to your unblocked phone. Coverage has to span every screen, ideally in one synced session.
This matters because the cost of each little check-in is far higher than it feels. Research by Gloria Mark at UC Irvine found it takes around 23 minutes to fully refocus after an interruption, so a five-second YouTube glance is never just five seconds. With the average person spending close to six to seven hours a day on screens, a half-closed block barely moves the needle.
Use a cross-device blocker that holds one block list across all your devices. Add the apps and their websites once, start a session, and Instagram, TikTok and YouTube lock everywhere at the same instant, with no app-to-web or laptop-to-phone escape route left open.
Step by step: block Instagram, TikTok and YouTube everywhere
This is the reliable way to do it with a cross-device blocker. The same flow works in Focus, Freedom, or any tool that syncs one session across devices.
- 1Install your cross-device blocker on every device you want covered: your phone and your computer at minimum, plus a tablet if you use one.
- 2Sign in to the same account on each device. This is what links them into a single synced session.
- 3Create one block list and add the three apps: Instagram, TikTok and YouTube.
- 4Add the matching websites to the same list: instagram.com, tiktok.com and youtube.com (this closes the browser loophole).
- 5Add the related domains people forget: m.youtube.com, mobile versions, and any short-link or embedded paths your blocker lets you specify.
- 6Turn on strict / lock mode so you cannot remove an app or end the session early while it runs.
- 7Start the session, or schedule recurring focus windows (for example weekdays 9am to 1pm) so it runs without a daily decision.
When the session starts, all three apps and their sites lock on every signed-in device at the same moment. There is no app-to-web hop and no laptop-to-phone hop left. That is the whole point.
Per-app notes: the gotchas for each one
Instagram's biggest trap is the website. Block the app and instagram.com still loads in any browser, so add both. Reels is the time sink to watch for, and because Instagram is woven into other apps via 'share to' and login flows, a blocker that handles the app plus the domain is more reliable than a browser-only extension.
TikTok
TikTok is built for autoplay, so even brief access restarts the loop. Block the app and tiktok.com together. On desktop especially, people drift to the website out of habit, so the site block matters as much as the app block here. If your blocker supports it, also cover any regional or short-link domains.
YouTube
YouTube is the hardest of the three because it is genuinely useful, so a hard block can be too blunt. Many people block the YouTube app and youtube.com plus m.youtube.com during deep-work hours, then schedule the block to lift in the evening. Watch the embedded loophole: YouTube videos play inside other sites and apps, so site-level blocking and scheduling beat trying to police every embed.
The single most common mistake is blocking the three apps and feeling done, then opening the sites in Safari, Chrome or Edge an hour later. Whatever tool you use, confirm it blocks instagram.com, tiktok.com and youtube.com as well as the apps. On iPhone, Apple's Screen Time can restrict websites across every browser at once, but only on Apple devices.
Tools that can block all three across devices
Not every tool can do the full job, app plus website, phone plus computer, at once. Here is how the realistic options compare. Capabilities change, so confirm current details on each product's site.
| Tool | Blocks apps | Blocks websites | Phone + computer at once | Strict mode |
|---|---|---|---|---|
| Focus | Yes | Yes | Yes | Yes (Lock Mode) |
| Freedom | Yes | Yes | Yes | Yes (Locked Mode) |
| Cold Turkey | Yes (desktop) | Yes (desktop) | No (desktop only) | Yes |
| Opal | Yes | Partial | Apple only | Yes |
| Apple Screen Time | Apple apps | All browsers (Apple) | No (Apple only) | Passcode only |
The honest read: if you are entirely inside Apple's ecosystem, Screen Time and Opal can cover Instagram, TikTok and YouTube reasonably well. The moment you mix an iPhone with a Windows laptop, or an Android phone with a Mac, you need a dedicated cross-device blocker, because the native tools do not sync a single block across two ecosystems.

Make it stick: strict mode and scheduling
A block you can switch off in two taps is a suggestion. Two features turn it into a real commitment.
Strict / Lock Mode stops you from ending the session early or pulling Instagram, TikTok or YouTube off the list until the timer ends. It moves the decision to the start, when you are motivated, instead of every time the itch hits. Scheduling auto-starts your blocks on a recurring basis, so the three apps lock during your focus hours without you remembering to flip a switch. Together they turn 'I should stop scrolling' into a system that just runs.
Block them with friends, not just alone
Willpower is a finite battery; accountability is a renewable one. Blocking these apps alongside other people makes it dramatically easier, because you are no longer relying on yourself in isolation. Focus Huddles let you start a shared session with a friend, a study partner or your whole team, so everyone locks Instagram, TikTok and YouTube at the same time and you keep each other honest.
The bottom line
To truly block Instagram, TikTok and YouTube, close both loopholes: block each app and its website, and do it on every device in one synced session so there is no second screen to escape to. Add a strict mode so you cannot wriggle out, schedule it so you do not have to think about it, and you have turned three of the stickiest apps ever built into a non-event during the hours that matter. That is exactly what Focus is built to do.
Frequently asked questions
- How do I block Instagram, TikTok and YouTube on all my devices?
- Use a cross-device blocker, add the three apps and their websites (instagram.com, tiktok.com, youtube.com) to one block list, sign in on every device with the same account, then start or schedule a session. The block applies to your phone and computer at the same time, closing both the website and the device loopholes.
- Why do I need to block the website as well as the app?
- Because Instagram, TikTok and YouTube all have full websites. If you only block the app, your brain simply opens the site in a browser instead. Blocking both the app and its matching domain closes that loophole, which is the single most common mistake people make.
- Can I block these apps on my phone and computer at the same time?
- Yes, with a cross-device blocker like Focus or Freedom. Signing in to the same account on each device links them into one synced session, so starting a block on your laptop also locks the apps on your phone instantly. Single-device tools leave the other screen open.
- How do I block YouTube but keep it for the evening?
- Schedule the block. Many people block the YouTube app and youtube.com plus m.youtube.com during deep-work hours, then set the schedule to lift in the evening. Scheduling lets you stay strict when it matters without banning a genuinely useful tool entirely.
- Can I block these apps so I can't unblock them mid-session?
- Yes. Strict or lock modes prevent you from ending a session early or removing an app from the list until the timer ends. Focus calls this Lock Mode. It is the most effective setting if you tend to talk yourself out of focus once the craving hits.
- Does Apple Screen Time block TikTok and Instagram on all devices?
- Apple Screen Time can block apps and restrict websites across every browser, but only on Apple devices signed in to your Apple ID. It will not touch a Windows laptop or an Android phone, so a mixed setup still lets you device-hop between blocked and unblocked screens.
- What about blocking embedded YouTube or shared TikTok links?
- Site-level blocking plus scheduling handles this better than chasing every embed. Block the core domains and use a strict, scheduled session so the apps and sites are simply unavailable during focus hours, rather than trying to police every place a video might appear.
- When does Focus launch?
- Focus is pre-launch with an early-access waitlist, so you cannot download it yet. Joining the waitlist puts you first in line for cross-device blocking of Instagram, TikTok and YouTube with Lock Mode and Huddles across Windows, macOS, iPhone and Android.
