Digital Habits: Blocker

Free up headspace. Block distracting websites and apps with Digital Habits: Blocker — an open-source focus tool built on our 10+ years of research into digital distraction at the University of Oxford (digitalhabits.org/research).

Create focus spaces, choose when they block, and decide how difficult it should be to get past a block early.

KEY FEATURES

Website Blocking: Block distracting websites in popular browsers, including Chrome, Firefox, Samsung Internet, Edge, Brave, Opera and Vanadium.

App Blocking: Show a full-screen block screen when you open a distracting app while a focus space is on.

Focus Spaces: Create and organise multiple focus spaces for different contexts, and run them manually, daily or weekly.

Override Protection: Set your own difficulty — choose how many random words you must type to unlock a blocked app or website, or to edit or switch off an active focus space.

Temporary Unlock: Choose what happens after you unlock — the focus space switches back on automatically after 5 minutes to 24 hours, or stays off until you turn it on again.

Stacking Blocks: Run multiple focus spaces at the same time.

Always On: Focus spaces keep running even when the app is closed.

OPEN-SOURCE & PRIVACY-FIRST

Digital Habits: Blocker is fully open-source and collects zero user data. Everything stays on your device.

Please note: The app uses the Android Accessibility API to support people who struggle with digital distractions. It reads only which app is open and the address bar of supported browsers, to detect what you have chosen to block. This information stays on your device and is never shared. Use of the API is only permitted with the user's consent. Use at your own risk.
