AntiRot is a focus blocker that replaces flimsy timers with real friction. Most blockers let you tap "5 more minutes" and undo everything — AntiRot makes you complete a challenge (breathing reset, math problem, journal prompt, push-ups) before a blocked app or site unlocks. Group apps + websites into rule sets instead of configuring each one, add strict mode and cooldowns for extra resistance. Built for anyone who opens "just a quick check" and loses an hour.
