Klaro: App Blocker
Unlock with intention.
$4.99 · Designed for iPad. Not verified for macOS.
Block any app behind an affirmation you write. Type it word-for-word to unlock—then Klaro re-locks automatically when your time window closes.
Klaro blocks apps at the OS level using Apple's Screen Time API. To unlock, you type your own affirmation exactly as you wrote it. When your time window closes, the apps lock again automatically.
PERFECT FOR
• Social media you want to use intentionally, not mindlessly
• Any app that pulls you away from what matters
• Anyone who wants friction before distraction
HOW IT WORKS
1. Create a block group and pick the apps to block.
2. Write your affirmation — a phrase that means something to you.
3. When you want access, open Klaro, type your affirmation exactly, take a selfie, and set your time window.
4. Klaro unlocks the apps for that window, then re-locks them automatically.
5. Your unlock history and selfies are saved so you can see your patterns over time.
