Cat Gatekeeper · Chrome extension

A Japanese developer just released this and it went viral for good reason: when you hit your social media time limit, a chubby orange cat physically plants itself across your screen and refuses to move until your break is over. Free, no ads, no data collected.

How to set it up

1. Open Chrome and go to the Chrome Web Store. Search “Cat Gatekeeper” or use the link below.

2. Click Add to Chrome → Add extension. The cat icon appears in your toolbar.

3. Click the cat icon → set your usage limit (default: 60 min) and your break time (default: 5 min).

4. Open Instagram/TikTok/etc. as normal. The timer only counts while that tab is active — switch tabs and it pauses.

5. When time’s up, the cat appears and blocks all controls. You can’t skip it — you have to wait out the countdown.

Pro tip

Set your first session to 30 minutes and the break to 10. The discomfort of being forced to stop is the whole point — shorter limits = more cat visits = actual habit change.

→ Install Cat Gatekeeper on Chrome Web Store

Part 2 — Mobile

One Sec · iOS & Android

Mobile apps can’t spy on each other by design — only your OS can. One Sec works around this by intercepting apps before they open, forcing a pause screen. You can upload a custom cat photo so your own judgemental feline stares you down.

📱 iOS + Android

How to set it up

1. Download One Sec from the App Store or Google Play. It’s free with a paid tier for more features.

2. Open One Sec → tap Add App → choose Instagram, TikTok, or whichever app you want to gatekeep.

3. In the app settings, tap Custom background and upload a photo of your most unimpressed-looking cat.

4. Set a delay timer — 10 to 30 seconds works well. Every time you tap the app, the cat appears and makes you breathe before you can proceed.

5. Stack it with your phone’s built-in limits: iOS Screen Time or Android Digital Wellbeing. One Sec handles the friction; Screen Time handles the hard cap.

The science bit

The delay doesn’t have to be long. Research on habit loops shows that even a 10-second pause is enough to interrupt the automatic open-without-thinking behavior. The cat is doing real work.
