Blok helps you reduce screen time by making distractions harder to access. HOW IT WORKS ↓ 1. Choose the apps and websites you want to block 2. Start a Blok session by scanning a product barcode or Blok Card 3. To unBlok, complete the physical action again WHY BLOK WORKS ↓ Most app blockers are too easy to bypass.

With Blok, you can: - Block distracting apps, websites, and categories - Use a product barcode or Blok Card as your physical key - Create focus modes for work, sleep, study, or personal time - Schedule automatic Blok sessions - Take limited breaks without fully giving up - Combine modes for stricter blocking - Track your Blok streak and time Blok'd - Add friends and compare progress in Blok World - See Blok'd status on your Lock Screen with Live Activities Blok is built for people who want a real-world way to reduce doomscrolling, social media overuse, and phone addiction.
