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
• 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.

Action Required: Update Your Blocker Configurations. We have made foundational changes to how all three blockers (app, website, and short-form) operate. As a result, your existing configurations may no longer work as expected.
We highly advise reviewing and updating your settings. Additionally, you will need to reconfigure both Tamper Protection and the Settings Change Delay.
We apologize for any inconvenience this may cause!
