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
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 so you can study or work in peace
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 nudges that run as overlay when you use an app
Attention Span Tracking: see how long you stay with short form videos before moving on


See your time

Usage Analytics: clear breakdowns of how long you spend in each app and website
Focus Statistics: track your focus sessions and your progress over time
Live Scroll Counter: a real time count of how many short videos you have scrolled
Session Timer: a live timer of how long the current app has been open
Home Screen Widgets: keep your stats and quick controls on your home screen


Choose how hard it is to give in

When you use all the time available in a schedule, you decide what it takes to get back in.

Strict Blockade: no access at all
Timed Unlocks: each unlock lasts a short set time, like 5 minutes
Dynamic Unlocks: pick the unlock length yourself each time
QR or Barcode Unlock: scan a real barcode, like one on a book, so you have to get up and move
Sentence Retyping: type out a full sentence before the app will open
Unlock Limits: cap how many unlocks you get every few hours
NFC Unlock: use a physical NFC tag to make unlocking a deliberate action
Adaptive Math: solve a changing math challenge before you can unlock


Built for developers

The Curbox API lets approved apps start Focus Mode, change Curbox settings, and read usage statistics. You stay in control of which apps receive access.


Curbox is the app blocker for anyone who wants to block distracting apps and websites, cut screen time, and take back their focus. Free, open source, no ads.
