Getting started is simple.

In just 60 seconds a day, you’ll see what’s really driving changes in your HRV, stress, sleep, and weight.

1

Daily Journal Check-In

Every day, you’ll track just a handful of impactful variables—like alcohol, sleep, stress, caffeine, and cold exposure.

Why it matters: These inputs form the foundation of your personal data model.

2

Wearable Data

Oura, Apple Watch, Whoop Garmin, Fitbit—we use the biometric data you’re already collecting.

Bring your own device.

3

Track and Complete

We analyze your habits in context—showing how multiple behaviors work together to affect your biometric outcomes.

No surface-level “correlations.” These are real, multivariable pattern insights.

“I had all the data—HRV, sleep, recovery—but no way to connect it to what I was doing every day. So I built the tool I couldn’t find.”

Every 2 weeks and each month, you’ll get a personalized breakdown of how your daily habits are impacting your body.

Top 3 Positive & Negative Habits

We highlight the inputs most strongly associated with improved or worsened metrics—like HRV, stress scores, sleep quality, or weight.

Multivariable Pattern Insights

Not just one-to-one. We show you the layered interactions between habits.

Trendlines Over Time

Track your HRV, sleep, and other outcomes over time—alongside the behaviors that influence them.

We Correlate to Outcomes

We don’t just chart one habit against one result.
We use multivariable correlation to identify layered insights.

We Let You Go Into “Experiment Mode”

Ever wondered how stopping alcohol, meditating, or changing your bedtime actually affects your recovery?

You can run real-world tests.

We analyze your biometric changes across that period—and give you a summary of what moved the needle (and what didn’t).
