ReDD Block: Focus Simply
Open-source web & app blocking
Free · Designed for iPad. Not verified for macOS.
Free your mind. ReDD Block helps you block distracting apps and websites — backed by 10+ years of our award-winning research at the University of Oxford.
Take back your focus. ReDD Block is a powerful, open-source focus tool that helps you block distracting apps and websites — on your terms. Built on more than 10 years of research into digital distraction at the University of Oxford, ReDD Block is designed to reduce impulsive screen use without taking control away from you.
Create and customise blocklists, choose when and how long to block apps and websites, and hold yourself accountable with tailored override difficulties.
Key features:
• Block Websites: Instantly restrict distracting websites across browsers
• Block Apps: Temporarily restrict distracting apps while a block is active
• Custom Blocklists: Create multiple blocklists for different contexts — work, study, evenings, deep focus
• One-Off or Scheduled Blocks: Start a permanent or temporary block instantly, or choose when scheduled blocklists become active and how often they can repeat
• Visual Timeline: See your blocklists at a glance on a clear 24-hour timeline (larger screens only)
• Pause & Resume: Pause blocks when truly needed — and resume automatically
• Stack Blocks: Run multiple blocklists at once without conflicts
• Override Protection: Choose how difficult it should be to cancel a block early — from simple confirmation to maximum-difficulty challenges
• Always Active: Blocks continue running even if you close the app
ReDD Block is fully open-source and collects zero user data.

Hi folks,
This version comes with several updates to make ReDD Block more user-friendly on iPhone and iPad:
- Overriding/pausing a block now requires typing one word at a time for random words and gibberish, instead of all words at once. Max difficulty is now 500 words on iOS.
- Size of buttons and text has been increased on iPad
- Zoom controls are now next to Settings (to be out of the way) and have been stabilised.
- Design improvements and styling tweaks!
Please keep suggesting improvements to the app.
We hope you're enjoying ReDD Block!
