Free your mind. ReDD Blocker 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 Blocker 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, Fristed 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
• Allow mode: instead of blocking specific apps / websites, choose what you want to 'allow' and everything else gets restricted automatically
• Quick start: start simple blocking/allowing sessions in just a few clicks
• 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
Fristed is fully open-source and collects zero user data.

For those who think oh obviously you have to pay for this app no its free and does a good job and its easy to set up and get going plus you can make it harder for uou to go back amd do your bad habits
Hi folks,
This update comes with some helpful improvements!
- "Allow edits between blocks": a new setting that applies per-schedule that allows frictionless pause and editing of most schedule settings when there are no active time segments and no enforced blocking. This is off-by-default and can only be toggled on before starting a schedule or if the schedule is paused/stopped. This is especially useful for people who have high-friction barriers to make necessary changes to e.g. the timings of their schedules because of changes to their workday.
- other design improvements and styling tweaks
Please keep suggesting improvements to the app - you can do so at https://github.com/ulyngs/redd-block
We hope you're enjoying ReDD Blocker!
