Hey Product Hunt! 👋 I built Protocol66 because I kept failing at habits after 2-3 weeks. Turns out "21 days to form a habit" is a myth. Research by Dr. Phillippa Lally found it actually takes 66 days on average. So I made an app that forces me to do 66 days — no excuses. The rules are simple but strict: - Pick 5 daily habits - Do all 5 every day for 66 days - Miss one day = restart from Day 1...
Protocol6666-day habit challenge. Miss a day, start over.
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.
