Vitals engine

Apple Watch vitals, read against a personal baseline.

Heart rate and HRV stream from the watch into a bounded stress score. The companion adapts across four tiers — gentle when you're calm, protective when you're not.

Calm< 0.35
Elevated0.35 – 0.60
Stressed0.60 – 0.80
Crisis≥ 0.80

What's inside

Capabilities

On-device multimodal AI

Gemma 4 runs on the iPhone via Apple MLX — text, voice and images. Zero conversation bytes ever leave the device.

Predict distress before crisis

Apple Watch HR + HRV are measured against a personal baseline to compute a bounded stress score across four tiers: calm → elevated → stressed → crisis.

Private long-term memory

Echo remembers interests, sensory notes and calming preferences in encrypted on-device storage, with two-pass semantic deduplication.

Regulation tools

Guided breathing, curated and AI-narrated stories with a persona picker, and a daily mood survey — all designed for sensory calm.

Caregiver dashboard

Live vitals, HRV analytics, location, wearable camera feed and an activity log — with consent-bounded linking and instant revocation.

Two independent SOS triggers

A model tool-call and a life-threat text detector each independently dispatch SOS — either one alone is enough.

Caregivers, without compromise

Connected — only with consent

Live vitals, location, chat and SOS — gated by an active, consent-bounded link that revokes instantly on removal.
