Curbox is a free, open-source Android app that blocks distracting apps, websites, and short-video feeds like Instagram Reels and YouTube Shorts to help users reduce screen addiction. It offers granular scheduling, usage allowances, focus sessions, and configurable unlock challenges (QR scans, NFC tags, math problems) with no cloud or tracking.

Use cases

• block instagram reels and youtube shorts on android
• block distracting apps and websites on my phone
• reduce screen time and stop doomscrolling
• set daily app usage limits with schedules
• lock apps until I scan a QR code in another room
• start a focus session while studying or working
• track how much time I spend in apps and short videos
• open-source privacy-friendly alternative to screen time apps

When to choose

• you want a free, open-source, privacy-friendly app blocker with no cloud or subscriptions
• you need granular blocking like hiding only Reels/Shorts while keeping the rest of an app usable
• you want friction-based unlock challenges such as QR scans, NFC tags, or math problems
• you prefer installing from F-Droid and auditing the GPL-3.0 code

When to avoid

• you need an iOS or desktop blocker (iOS support is not yet released)
• you are uncomfortable granting Android accessibility permissions
• you want a managed parental-control solution with remote monitoring
• you need cross-device sync of blocking rules across platforms
