Monitor Elderly Health Vitals & Send Alerts with Apple Health, Twilio & Gmail

Description

What is Elderwatch
Elder Watch is a simple system that checks daily vitals — like heart rate, oxygen, and walking symmetry — using data from an iPhone or Apple Watch.
If something looks off — say oxygen drops or heart rate spikes — it flags that as “attention required.”
And depending on that status, it can either:
Email a daily report to a caregiver
Or if there’s an alert — trigger a phone call via Twilio
Why do we need this
Elder Watch can help older people living alone for children or care givers to keey an eye on without obsessively checking apps.
It’s useful for clinics that run home-care programs.

Requirements
Self hosted or cloud N8N
Apple health vis iphone/watch
Twilio VOIP phone number (to place a call)

Workflows
Core workflow for getting health data, processing and making a phone call.
Twilio workflow to invoke Calls API to place an outbound voice call.
