Scroll Brake

Scroll Brake is a native iOS app and Chrome extension that interrupts compulsive doomscrolling through progressive mental math friction instead of rigid lockouts. Set up to 3 separate daily limit schedules covering unlimited apps and websites for free. When your time limit hits, solve a quick arithmetic equation to unlock a timed extension or close the app. 100% local on-device privacy with zero telemetry. Includes a Free Forever tier and a $17.99 one-time Lifetime option.
