You can't grow
what you don't measure.
The Growth Delta 10 Day Challenge Tracker is the core of the app: every habit across Spirit, Soul, and Body rolls up into one 10-day score. Hit 80% and you win the cycle — then you start the next one. Ten days at a time, all year.
Every other habit app gives you a scattered list.
The Growth Delta 10 Day Challenge Tracker gives you one number instead. Every habit across Spirit, Soul, and Body rolls up into a single 10-day score. Hit 80% and you win the cycle — then the tracker resets and you run it again. No juggling three separate checklists in your head, no guessing whether today was "good enough." Just one tracker, ten days at a time, all year long.
Identity doesn't shift because you decided it should. It shifts because you did the same things, on purpose, long enough for them to become who you are. — The Growth Delta Method
Spirit, Soul, and Body — three sides of one person.
Growth Delta doesn't measure your day as one flat list. It splits it into the three dimensions that make up a whole person, so you can see exactly which part of your life is actually getting your attention.
Spirit
Your connection to something bigger than your schedule. God, your faith, prayer, daily Bible reading, reflection — this keeps you steady when the day doesn't cooperate.
Soul
Your mind, desires, and emotions. Developing a healthy soul with what you read, think, feel, and carry. The mindset work that shapes how you respond before the world does it for you.
Body
The physical vessel for everything else — training, sleep, nutrition. Your body keeps score whether you're watching or not.
The Growth Delta 10 Day Challenge Tracker.
This is the core of the app. Every 10 days, your three pillars — Spirit, Soul, and Body — roll up into one score. Hit 80% and you've won the cycle. Then it resets, and you run the next 10 days. That's the rhythm — repeated cycles, all year, not a one-time challenge.
One score, ten days
Up to 180 possible checks across the cycle — 18 pillar habits, tracked every day for 10 days.
Nothing hides
Spirit, Soul, and Body are scored inside the same tracker, so no pillar can quietly carry the other two.
80% is the win line
You don't need a perfect cycle — you need a consistent one. Hit 80% and the challenge is won.
Always visible
Your live percentage and streak sit on top of the tracker every time you open the app.
Your Daily 10.
This is a completely different tool from the Challenge Tracker above. It doesn't touch your 10-day score — it's just a simple daily checklist for whatever else needs to get done today.
Ten tasks, today only
List up to ten one-off tasks — errands, chores, whatever isn't a recurring pillar habit.
100% to win the day
Finish all ten and you've won the day. There's no 80% threshold here — it's all or nothing.
Not part of your score
Daily 10 checks never feed the 10 Day Challenge Tracker. The two systems run side by side, independently.
Set up your 10 Day Challenge Tracker in three steps.
Load your habits
Pick up to six habits in each pillar — Spirit, Soul, and Body. That's your tracker, built.
Check off your 10 days
Every day for the next 10, your pillar checks feed straight into one running score — no separate math to do.
Hit 80%, win the cycle
Cross the 80% line and the cycle is won. The tracker resets immediately and day 1 of the next 10-day cycle starts — this repeats all year, not just once.
Up to six habits in each pillar.
However you define Spirit, Soul, and Body for yourself, here's where those habits live in the app.
Spirit
Up to six habits, tracked day by day across your 10-day cycle.
Soul
Up to six habits, tracked day by day across your 10-day cycle.
Body
Up to six habits, tracked day by day across your 10-day cycle.
The 10 Day Challenge Tracker, in action.
Challenge Group.
Growth happens in community. Invite friends to run the same 10 days. Everyone tracks their own progress, and you all share one leaderboard.
Invite your people
Bring in friends, family, or your team to start the same 10-day cycle together.
Everyone tracks their own
Each person still runs their own pillars and their own score — nobody's habits get mixed up with anyone else's.
One shared leaderboard
See where everyone in the group stands in real time. Nothing pushes consistency like a little friendly pressure.
Year Report.
Track your progress across the whole year, not just one cycle at a time. Your streaks, your pillar balance, and every cycle you've run — updated in real time.
12 months at a glance
A full year of activity in one heatmap, so you can see exactly where your consistency held and where it slipped.
Pillar balance, year to date
Spirit, Soul, and Body scores tracked across the whole year, not just the current cycle, so imbalance shows up early.
Every cycle, logged
A running history of every 10-day cycle you've completed, with the score for each one, so you can see the trend over time.
Updated in real time
No waiting for a weekly digest. Your Year Report reflects every check the moment you make it.

Everything you're wondering.
What exactly is the 10 Day Challenge Tracker?+
It's the core system in the app. Every habit across your three pillars is scored inside one 10-day cycle. Hit 80% of your total checks and you've won the cycle — then it resets and you run the next one. It's not a one-time challenge; it's how you track your habits all year, ten days at a time.
Why 10 days instead of daily or monthly?+
A single day is too noisy to mean anything, and a month is too long to stay motivating. Ten days is short enough to see the finish line and long enough to prove the pattern is real.
What happens after my 10 days are up?+
The tracker resets and a brand new 10-day cycle starts immediately — there's no end point. You keep running cycles back to back, all year, and your streak carries across every cycle you win.
Does the Daily 10 affect my Challenge Tracker score?+
No. The Daily 10 is a separate checklist with its own 100% win. It never adds to or subtracts from your 10-day pillar score.
Is there a free version?+
