How to Block TikTok, Instagram and YouTube — For Real (iPhone & Android)
Blocking TikTok “for good” — you've probably already tried: time limits, deleting the app, Focus mode… and every time, it comes back. The problem isn't you: most blocks can be switched off in two taps. Here's every method out there, its honest limits, and the one that actually holds.
On iPhone: Screen Time
Settings → Screen Time → App Limits: you can cap TikTok, Instagram or YouTube at 30 minutes a day, or block them with Downtime.
The catch: when the moment of truth arrives, your iPhone offers “Ignore Limit”. Even with a passcode, you end up knowing it (or guessing it). Screen Time has a structural flaw: the person who sets the limit is the person who can lift it. We covered this in detail here: why Screen Time isn't enough.
On Android: Digital Wellbeing
Settings → Digital Wellbeing → App timers. Same idea, same flaw: the timer can be changed in ten seconds, and nothing stops you from doing it.
Third-party blocking apps
Forest, Opal, One Sec, AppBlock… These apps add smart friction (delays, virtual trees, breathing screens). They work for a while — then you learn to get around them, or you uninstall them in a moment of weakness. An app is still just software: it can't stop you from deleting it.
Deleting the apps (and the browser trap)
Deleting TikTok genuinely helps for the first few days. But the browser is still there: tiktok.com, instagram.com and youtube.com work just fine in Safari or Chrome. And reinstalling an app takes thirty seconds.
Blocking at the DNS or router level
Technically possible (your router's parental controls, DNS filtering), but a hassle to maintain — and useless the moment you switch to 4G/5G.
The method that holds: physical blocking
The only way to make a block genuinely binding is to take the unlock key… out of your phone. That's the principle behind Lock-IN, a box made in France: you pick the apps to block (TikTok, Instagram, YouTube, whatever you want), you start a session with one tap, and to unlock, you have to physically bring your phone to the box. Box left at home = no way to cave in class, at the office or on your commute. You keep calls, texts and GPS.
Bonus: it works the other way round too. In parental mode, the parent runs the sessions — your teen can't change them or get around them.
The bottom line
| Method | Effectiveness | Workaround |
|---|---|---|
| Screen Time / Digital Wellbeing | Low | “Ignore Limit” in 2 taps |
| Third-party apps (Forest, Opal…) | Medium | Uninstalling, settings |
| Deleting the apps | Medium | Reinstalling, browser |
| DNS / router | Varies | 4G, complexity |
| Physical blocking (Lock-IN) | High | None without the box |
