Sundial reads the health data your family already shares from Apple Health and turns it into one calm morning brief. No dashboards to decode. No news is good news, made visible.

Sundial · 7:02 AM
Mom’s resting heart rate is back to her usual range.
Morning brief — placeholder, not a real screen
Good morning
Your family at a glance · Today
Mom — Slept well, 7h 24m · Heart rate steady · All good
Dad — Morning walk done, 2.1 mi · All good
Sam — Restless night, 5h 10m · Worth a look
Everyone is close to their usual patterns. Sam slept poorly two nights in a row — a good day for a check-in call.
Illustrative example data, not a real family.
Welcome to Sundial
Your parents’ health data already exists. It sits in apps nobody opens, in numbers nobody translates. Sundial turns it into one sentence you can act on, every morning.
How it works
Watch
Sundial quietly follows the signals that matter — sleep, activity, heart rate, and glucose where a sensor is shared — and learns what is normal for each person.
- Connects to Apple Health in a couple of taps
- Each person gets their own baseline, not a generic chart range
- Family members choose exactly what they share
Mom · Last 7 days — illustrative example
Sleep 7h 18m avg
Resting heart rate 62 bpm
Steps 6,940 avg
Trend Steady
Know
Numbers become a sentence. Sundial compares today against each person’s own normal and tells you what changed, in words a non-clinician can use.
- Changes are measured against the person, not a population average
- Explanations say what a change usually means, and what it doesn’t
- Sundial never diagnoses. It points, you decide.
What changed — illustrative example
Sleep, two nights Down 1h 40m
Resting heart rate Up 6 bpm
Everything else Usual
In plain words: two short nights and a slightly raised heart rate. Often just a busy week. Worth watching one more day.
Act
Most mornings, the brief says everyone is fine and you get on with your day. When something is off, Sundial suggests the smallest useful next step.
- A prompt to call, a question to ask, a visit worth booking
- Urgent patterns are flagged the same morning, not in a weekly report
- Notes you add are shared back with the family, so everyone sees the same picture
Suggested next step — illustrative example

Shared with Whole family
Built for families, not dashboards
Three commitments shape every screen in Sundial.
01
Calm, not alarming
Sundial uses plain sentences, not alarms. Most mornings the brief says everyone is fine, and you get on with your day.
02
Consent runs both ways
Each person chooses exactly what they share, and can take any signal Private or revoke sharing at any time.
03
Family first, clinicians in the loop
Sundial is for family, not a clinic. It never diagnoses — it points, you decide, and a clinician decides what it means.
