Always there.Never in the way.
A single sensor watches heartbeat, breath, falls, and movement — and only speaks up when something needs attention.
- No wearable required
- Encrypted by default
- Works offline
- No subscription
From outlet to peace of mind in a minute.
One sensor. No wearables. No cameras. No subscriptions to worry about.
Plug it in
A small ESP32 sensor plugs into any outlet. No tools, no installer, no wiring.
It learns the room
A 30-second baseline calibration teaches the sensor your normal — heart rate at rest, breath cadence, and routine motion.
Watches quietly
Continuous monitoring 24/7. Vitals, breath, falls, and movement — all processed locally on the sensor.
Alerts only when needed
Family members get a notification only when something needs attention. No false alarms, no notification fatigue.
Four signals. One quiet device.
A single sensor, ambient and contactless — no wearables, no cameras, no microphones.
Heartbeat detection
Beat-to-beat tracking that flags arrhythmias and rate anomalies before they become emergencies.
Breathing detection
Continuous respiratory rate monitoring — catches apnea episodes and abnormal patterns through the night.
Fall detection
Instant alerts the moment a fall is detected, sent to the people who need to know.
Movement detection
Activity patterns over the day. Spot prolonged stillness, restlessness, or routine drift.
One device. No subscription required.
Pay once for the sensor. The Family plan is optional, for households with more than two caregivers.
