Build 14 healthy habits.
One at a time.
OneStack introduces one new habit per week. Master it before the next unlocks. By week 16, you maintain the full stack — without ever feeling overwhelmed.
How OneStack Works
One Habit Per Week
Each week introduces a single new daily habit. Focus on that and nothing else.
Master to Unlock
Complete the habit on 5 of 7 days. Then — and only then — the next week opens.
Anchors Carry Forward
Mastered habits become permanent daily anchors. Your stack grows every week.
Your 16-Week Stack
4 phases. 14 habits. Check-in weeks to review your progress.
Built to Keep You Going
Mastery Gates
No skipping ahead. You must prove consistency before unlocking the next habit.
Anchor System
Graduated habits become quick-tap daily check-offs that carry forward permanently.
Check-In Weeks
Weeks 4, 8, 12, and 16 are dedicated to reviewing 21-day trend lines across all habits.
Coach Tips
Contextual guidance each week — when to schedule, what to eat, how to adjust.
Guided Workouts
Built-in 20-minute bodyweight circuits with timer for the strength training weeks.
Celebrations
Over-the-top level-up animations when you master each habit. You earned it.
Start with a glass of water.
Week 1 is the simplest habit there is. The rest builds from there. No overwhelm. No information overload. Just one thing at a time.
