How it gets to know you

It builds a complete picture of your life.

Not from more data, but from deeper understanding.

It remembers everything.

You tell it in your own words. Big moments, small details, and everything in between.

Examples
Had coffee with Tom
Felt anxious before my meeting
We moved into a new apartment

It watches your body's signals.

Sleep, heart rate, glucose, activity, recovery and more — pulled from the trackers you already use.

Examples
Lower HRV overnight
Shorter deep sleep
Evening glucose spike

It runs experiments.

It helps you test what might be causing what — with structured trials that actually teach you something.

Examples
Cut late coffee for 2 weeks
Morning sunlight daily
More protein at dinner

It discovers what matters.

It connects the dots, finds patterns you would never see, and turns them into insights you can use.

Examples
Sunlight → better sleep
Late coffee → worse HRV
Walking → calmer mood

It helps you take action & improve.

Personalized recommendations, next steps, and a playbook that evolves with you.

Examples
Do more of what works
Avoid what hurts
Track what matters

From noise to know-yourself.

Health Decoder finds the patterns most apps miss because it sees your whole story.

Understands timing, context, and sequence

Finds cause-and-effect, not just correlations

Tracks your experiments and learns what works

Explains the why in simple, confident language

Outdoor time is strongly associated with your best sleep.

On days you spend 60+ minutes outside (ideally in natural light), your sleep quality is significantly better.
