What Protocol66 does

A 66-day habit challenge based on research, not bro culture. Pick 5 daily habits. Complete them for 66 days. Miss a day, restart from Day 1. Why 66? Research shows habits take 66 days to become automatic — not 21, not 75. Choose from 8 categories: Move, Mind, Fuel, Hydrate, Reflect, Sleep, Connect, Create. Optional rest days. Friends + leaderboard for accountability. Not another gentle reminder app. Real challenge, real consequences. $4.99 lifetime. No subscription.

Love the no-mercy approach — 66 days, miss one, restart. Research-backed and brutal in the best way. Exactly the kind of accountability tool that actually works for building real habits.
