Scroll Brake is now on Chrome! It stops mindless tab-switching by adding cognitive friction before distracting websites open: • Mental math barrier: Solve quick arithmetic to unlock sites. Each repeat unlock gets tougher. • Active-time tracking: The timer only ticks when you actively type, scroll, or move your mouse. • Surgical blocking: Block addictive feeds (like YouTube Shorts) while keeping tutorials open. • 100% private: Zero tracking, no accounts, runs locally.

Scroll Brake is a lightweight (~4MB) iOS app that replaces mindless scrolling with healthy mental friction. Standard limits fail because tapping 'Ignore' is pure muscle memory. Instead of an easy bypass, Scroll Brake locks distracting apps behind quick math puzzles, cooling impulsive dopamine cravings in 10 seconds. Built natively on Apple's Screen Time API with zero battery drain and 100% on-device privacy. Up to 3 rules are completely free forever, with no ads, trackers, or subscriptions.
