Scientific studies suggest it takes an average of 66 days for a new behavior to become automatic. Detox 66 guides you through three distinct phases: The Struggle, The Shift, and The Success.
Challenge Phases
Visual feedback is critical for discipline. Watch your progress grow through minimalist charts and earn milestone badges that celebrate the small wins on the road to a major victory.

Track up to 3 active challenges simultaneously without feeling overwhelmed.
Optional biometric lock to keep your personal growth journey for your eyes only.
Generic notification labels that remind you to check in without revealing the habit.
Daily bite-sized insights into the neurobiology of dopamine and discipline.
No social feeds, no leaderboards, no gamified noise. Just you and your goal.
