Break the doomscroll loop.
Curbox helps you stop opening distracting apps on autopilot. Choose what gets in your way, set limits that fit your day, and add a pause before you can continue. You stay in control of what is blocked and what it takes to unlock it.
A simple pause before the scroll
Curbox puts a small, useful gap between the urge to open something and the moment you get pulled in. That gap gives you time to decide whether you really want to keep going.
Pick the apps, websites, Reels, or Shorts that distract you. Choose when Curbox should step in, then decide how easy or difficult it should be to continue. You can stay fully blocked, wait before continuing, or complete a challenge that makes you stop and think.
What you can do
Block distracting apps and websites
Choose the apps and websites that take too much of your time, then decide when they should pause.
Stop Reels and Shorts
Block endless short-video feeds while keeping the useful parts of apps like Instagram and YouTube available.
Choose how you unlock
Stay fully blocked, wait for access, or earn it with a challenge. Scan a QR code or barcode, tap an NFC tag, solve adaptive math, type a sentence, or state why you want to continue. See every unlock option.
Add extra guardrails
Add a countdown before unlocking, limit how often you can continue, require daily focus time, or show yourself a message that brings your goal back to mind.
Set limits that fit your day
Use daily limits, schedules, cooldowns, or a cap on how many times you can continue. Make rules strict when you need them and relaxed when you do not.
Start a focus session
Temporarily pause distractions while you study, work, read, exercise, or spend time with people you care about.
See where your time goes
Check how long you spend in apps and on websites, see how many short videos you have watched, and track your attention span while scrolling them.
Make your phone less tempting
Turn distracting apps grayscale, hide the parts you do not want to see, quiet notifications, and show reminders that bring you back to your intention.

Frequently asked questions
Is Curbox free to use?
Yes. Curbox is free, with no ads, subscriptions, or paid tiers.
What can Curbox block?
Curbox can pause whole apps and websites, or just distracting parts such as Instagram Reels and YouTube Shorts. You choose exactly what you want help avoiding.
What happens when I reach a limit?
Curbox shows a pause screen instead of letting you fall straight back into the app or website. What happens next is your choice: remain blocked, wait before continuing, or complete a challenge that adds some effort.
What unlock choices are available?
You can remove the unlock option completely, wait for a fixed or changing amount of time, or require some effort. Effort challenges include scanning a saved QR code or barcode, tapping an NFC tag, solving adaptive math, typing a sentence exactly, or writing down what you intend to do.
Can I make an unlock stricter?
Yes. Add a countdown before the unlock choice appears, limit how many times you can continue within a period, require a certain amount of focus time each day, or display a personal message that reminds you why you set the block.
Does Curbox keep my information private?
Your rules and usage history stay on your phone by default, and you do not need an account for the core features. If you choose to use Sync, your synced information is protected with end-to-end encryption. See the privacy policy for full details.
Is Curbox available for iPhone?
