Sleep is the only time your body gives a clean, consistent signal — no movement, no meals, no stress distorting the data. Every night is a new baseline. Halo reads it through the walls, passively, without waking anyone up.
Push Halo into any standard outlet. The sensor powers on, the LED ring pulses once, and it immediately starts searching for your WiFi network.
No shelf. No cord. No deciding where to put it. Any outlet in the room works.
Open the Halo app, tap the sensor when it appears, enter your WiFi password. The app walks you through naming the room and adding whoever sleeps there.
Halo creates a baseline over the first few nights. After that it knows what normal looks like for each person — and what to flag when something changes.
Go to bed. While you sleep, Halo builds your health picture — breathing rate, sleep stages, heart rate, and any anomalies worth flagging. Wake up to a sleep score and anything you should know.
If something happens that can't wait — a fall, an extended breathing pause — Halo notifies whoever you choose, in real time. Everything else waits until morning so it doesn't interrupt your sleep.
WiFi channel state information captures micro-movements in the signal as your chest rises and falls. Accurate to within half a breath per minute.
Radio signals pass through drywall, wood, and glass. One sensor covers a standard bedroom in any direction, including through the wall to an adjacent room.
Two people breathe at different rates. The sensor separates those frequencies and builds an individual health picture for each person in the room.
The same 30-second epoch standard used in clinical sleep studies. Every epoch classified as wake, light, deep, or REM using breathing patterns and motion variance.
A breathing pause over 10 seconds is flagged as an apnea event. AHI (apnea-hypopnea index) calculated across the night. Shareable report generated on request.
WiFi signal patterns cannot be converted back into images or audio. There is no footage to hack, subpoena, or leak. Physics, not policy, protects your privacy.
