How It Works
Four steps to gentle reassurance
Harmoni reads the data their Apple Watch is already collecting, learns what's normal, and gently nudges you when something shifts.
Connect
Their Apple Watch, your peace of mind
Setup takes about 10 minutes. No new gadgets — just the Apple Watch they already wear. Create a family circle, invite the people who care, and Harmoni starts reading HealthKit data passively in the background.
- Works with Apple Watch Series 6 and later
- One-time HealthKit permission — no ongoing fiddling
- Your loved one doesn't need to do anything differently
- Add family members, caregivers, and doctors to the circle
Understand
7 days to learn what's normal
For the first week, Harmoni quietly observes. It learns your loved one's personal baselines — their resting heart rate, sleep patterns, temperature rhythms, respiratory rate during sleep. Every person is different, so Harmoni calibrates to them, not population averages.
- Median-based baselines — robust against one-off anomalies
- Personal thresholds, not generic clinical ranges
- Calibration continues to refine over time
- No alerts during the learning period — just quiet observation
Detect
One number. Colour-coded. Clear.
The Harmoni Score distils multiple health parameters into a single, colour-coded number. Purple means all is well. Yellow means a mild shift. Orange means check in. Red means it's time for a closer look. Multi-parameter shifts — like elevated heart rate and poor sleep together — are what catch real events early.
- Tracks HR, SpO2, temperature, respiratory rate, sleep, and more
- Persistence scoring: sustained shifts carry more weight
- Designed to catch infections before they cause falls
- Wellness tool, not a diagnostic — observe and report
Nudge
Gentle alerts, not alarms
When something shifts, Harmoni sends a warm, clear nudge — not a clinical alarm. You get context, not raw data. 'Mum seems a little off today — might be worth a check-in.' If nothing shifts, you hear nothing. No news is good news.
- Morning and evening summaries, plus one mid-day nudge if needed
- Quiet hours respected (10pm–7am) — only true urgencies break through
- Voice calls for meaningful changes (gentle tier) and urgencies (warm tier)
- Family gets insight in plain language, not medical jargon
Privacy by Design
What Harmoni reads — and what it doesn't
Harmoni only accesses HealthKit wellness data. Nothing personal, nothing invasive.
What we read
- Heart rate
- Blood oxygen (SpO2)
- Wrist temperature
- Sleep duration & quality
- Respiratory rate (sleep)
- Activity & step count
What we never touch
- Location or GPS
- Messages or calls
- Photos or camera
- Microphone or audio
- Browsing or app usage
- Contacts or calendar
Designed to respect your time
Harmoni is intentionally restrained. We never nag, never overwhelm, and always respect your sleep.
3 notifications max
Morning summary, evening summary, and one mid-day nudge if needed. That's it.
Quiet hours respected
10pm–7am in your timezone. Only the things that truly can't wait break through.
Voice calls when it matters
Gentle calls for trending scores, and a warmer follow-up if something needs a closer look.
