A calm health intelligence

Your health, finally understood.

Sulis quietly unifies your supplements, Apple Health, workouts, recovery, and bloodwork — then writes a plain-language daily read so you actually know how you are. No rings to close. No guilt. Just clarity.

"Your HRV runs 12% higher on nights you take magnesium and sleep past seven hours. I'd keep that evening dose."

— Sulis, after noticing a pattern across six weeks of your own data

What Sulis does

Less tracking. More understanding.

Everything that shapes how you feel, gathered in one calm place — and quietly explained.

A daily readiness score

Sulis learns your own baselines from HRV, resting heart rate, sleep, respiratory rate, and wrist temperature, then scores your readiness for the day — time-of-day aware, never one-size-fits-all.

The daily read

A short, plain-language note on how you are and why — running on Apple Intelligence on-device, or with your own Claude key. Insight only when it matters, never noise.

Your supplement stack

Track everything you take, schedule doses around your training and sleep, get gentle reminders, and see interaction flags — all folded into the same readiness picture.

Bloodwork intelligence

Import your lab PDFs and Sulis reads the markers for you, canonicalizes the names, tracks trends over time, and shows where each value sits — in language a human can follow.

Apple Health & wearables

Connect Apple Health, Apple Fitness, Oura, and WHOOP. Workouts, recovery, steps, VO₂, and nutrition from the apps you already use flow in automatically — including a companion Apple Watch app.

Private by design

Your data lives on your device and syncs only through your own iCloud. No accounts. No tracking SDKs. No servers of ours collecting your health data. The app is free — no in-app purchases.

How it works

Three quiet steps

Set it up once in about two minutes, then let it run in the background.

01
Connect Apple Health and any wearables, and add what's in your supplement stack.
02
Import your lab PDFs — Sulis reads your markers and starts tracking the trends.
03
Each day Sulis scores your readiness from your own baselines, on-device.
04
Read a calm, plain-language note on how you are — and what's actually moving the needle.
