## What is CardioUnlock?

You already know you scroll too much. CardioScroll does something about it.

CardioUnlock blocks your social media apps — Instagram, TikTok, YouTube, whatever you pick — and only unlocks them when your heart rate is elevated. Connect your Apple Watch or any Bluetooth heart rate monitor, set your unlock threshold, and start moving. Your apps unlock automatically when you hit your target heart rate and lock back up when you stop.

No willpower required. No screen time limits you can ignore. Your heart rate is the key.

HOW IT WORKS

Pick the apps you want blocked
Connect your Apple Watch or Bluetooth HR monitor
Set your heart rate threshold (default: 110 BPM)
Start doing cardio — apps unlock automatically
Stop moving — apps lock after a 2-minute grace period
