Score
Built by physicians. Designed for serious optimizers.
System of Understanding
Your records tell you what happened. We help you understand what it means.
The EHR is a system of record. Formula Health is your system of understanding: the intelligence layer that turns your health data into direction.
We call it the Health OS.
Works with what you wear.
More integrations on the way.
The HOM Score
One score, your whole health.
Wearables, labs, and lifestyle inputs feed a single number you can act on — built on the Health Optimization System.
HOM Score
/ 100
Your health, in a number you can act on.
Longitudinal by design
Your health is a trajectory, not a snapshot.
Most health apps show you today. The Health OS remembers every day. CORA reads your HOM Score across months and years, surfacing the slow drift most people miss — and showing you exactly what moved the line.
Illustrative. Not real user data.
How it works
Three steps from data to direction.
01
Connect
Sync your wearables and HealthKit. Upload your labs.
02
Score
Get your HOM Score across every dimension that matters
03
Optimize
Get daily guidance from CORA. Real changes, tracked over time.
Wearables, Unified
Connect everything you already wear.
Sync Apple Watch, Whoop, and Oura, and CORA turns the raw stream of data (sleep, recovery, strain, heart rate) into one signal that actually means something. No more juggling apps that never talk to each other. No more one-sided health scores.
Labs, decoded
Connect & understand your labs.
Upload your bloodwork and CORA reads it the way an experienced physician would, flagging what matters, putting it in context, and tracking it over time.
A lab result is a record. What it means for you, in context, over time, is understanding. That's the difference Formula Health is built on.
