App Blocker: Curbox Detox

Curbox (formerly Digipauwse) is a free and open source app blocker and screen time tracker built for digital wellbeing and a real digital detox. As an app blocker it lets you block apps, websites, reels and shorts, then watch your screen time drop and your focus come back.

Block apps and websites

• App and Website Blocker : block any distracting app or website completely

• URL Path Blocking : block just one part of a site, like m.youtube.com/shorts, while the rest of YouTube still works

• Short Form Content Blocker : shut off Instagram Reels and YouTube Shorts so the feed stops pulling you back

• Instagram DM Exception : choose to allow Reels opened from your DM inbox

• Tamper Protection : make it difficult to uninstall Curbox or turn off its blocking service

• Settings Change Delay : make weaker rule changes wait before they take effect, giving you time to reconsider

Hide only the distracting parts

Granular UI Hiding lets you remove the trap inside an app without losing the app. Curbox lays a clean overlay over the exact area you pick, so everything else keeps working. For example, hide the YouTube home feed but keep search, blank out the Instagram explore tab, or the entire home feed while allowing posts from friends. You stay in control of what you see.

Stay focused

• Focus Mode : pause apps and websites for a set time, or use a Pomodoro timer for work and breaks

• Scheduled DND : turn on Do Not Disturb automatically at the hours you set

• App Specific Grayscale : drain the color out of Instagram while your Camera stays full color, so dull apps lose their pull

• Scheduled Usage Limits : set when a group is active and how much use is available during that time

• Mindful Messages : gentle overlay nudges with custom colors and variables to make each message your own

• Warning Messages : show a random message when you open a blocked app

• Attention Span Tracking : see how long you stay with short form videos before moving on

See your time

• Usage Analytics : daily and weekly views of time spent in each app and website, with a background you can choose
