Cat Lock
Read full descriptionHide full description
Cat Lock blocks your most distracting apps after you've used them too long. When time's up, your cat takes over the screen — and won't leave until you take a real break. HOW IT WORKS • Choose which apps to block — Instagram, TikTok, YouTube, X, Reddit, Discord, even games and shopping apps • Set your usage limit — 5 minutes to 2 hours • Use your apps normally until your time is up • When time's up, your cat takes over the screen • Watch a real cat video for 5 minutes • Apps unlock. Clock resets. Repeat. NOT ANOTHER BORING BLOCKER Most screen time apps either lock your apps all day or add an annoying delay to every single open. Cat Lock lets you actually use your apps — with real breaks built in. Instead of guilt, you get a cat. Usage-based, not punishment-based. WHAT MAKES CAT LOCK DIFFERENT • Usage-based blocking — time only counts while you're actually in the app • Real cat videos during every break — a different cat every time • New cats added all the time — the break never gets old • See your progress at a glance — track distractions blocked, streaks, and time reclaimed. • Per-app or combined limits — track each app separately or share one pool • Blocks apps AND websites — no Safari bypass • Works silently in the background — no willpower required THE CAT LOCK EXPERIENCE Your cat notices patterns. It counts every attempt your most tempting app makes. It shows you what you got back — not minutes, but movies, walks, and books. No screen time app has done it like this. And when you win the day, it tells you: "The apps tried. You won." PERFECT FOR • Doomscrollers who can't stop once they start • Anyone who opens an app for five minutes and looks up an hour later • Anyone whose willpower needs a gatekeeper • Cat people. Obviously. "Less doomscrolling. More life." Cat Lock requires a subscription to access all features.
