Halo monitors your whole family's health through the walls — breathing rate, sleep stages, heart rate, and more. Plug it in. That's it.

Most of what matters about your health
happens while you sleep.
Sleep is the only honest signal — no movement, no stress, no noise. Just your body telling the truth every night. Halo listens passively, through the walls, without waking anyone up.
A wall-plug sensor that disappears into any outlet. Plug it in and it immediately begins reading WiFi signals to detect breathing, motion, and health patterns — through walls, through sleep, through anything.
No camera. No microphone. No wearable on anyone's wrist or finger.
Push Halo into any standard outlet. The LED ring glows once and the sensor starts searching for your WiFi.
Open the app, tap the sensor, enter your WiFi password. Takes about 90 seconds. Name the room — "Master Bedroom," "Nursery" — and you're done.
Go to bed. Wake up to last night's sleep score, breathing data, and any findings worth knowing about. Halo never stops working.
Add a sensor to every room that matters. Halo learns each person's patterns and builds a health picture that's personal to them — automatically.
Two people, two separate health reports. Ben's sleep apnea. Sara's best week in a month. Same room, same sensor.
Ellie's breathing rate: 34 BPM. Zero pauses tonight. No camera. Nothing in the crib.
Active at 12:48 AM. Fourth late night this week. You know before you ask.
When grandma stays over, Halo adjusts. Add a sensor, tag her name, and she has her own health history.
Breathing elevated 3 days in a row. Sometimes precedes illness. Halo flags it before symptoms show.
Halo isn't a sleep tracker. It's a continuous passive health monitor. It runs while you sleep, while you rest, while you watch TV — and it learns what normal looks like for you.
Light, deep, and REM tracked through breathing patterns. Wake up to a score, a hypnogram, and time in each stage.
Breathing pauses over 10 seconds flagged and counted. AHI calculated overnight. Shareable report for your doctor.
Your breathing rate rises 2–3 days before symptoms appear. Halo tracks your personal baseline and flags the deviation.
Breathing rate, pause detection, time asleep. Nothing in the crib. Nothing on the baby. Just peace of mind.
Walking speed and stride change weeks before a fall happens. Halo learns your pattern and flags the decline early.
Two people, two different breathing signatures. Halo learns to separate them. Separate sleep scores, separate reports.
Halo reads WiFi signal patterns — the same physics your router already uses, pointed at the room instead of the internet.
There is no image. No audio. No footage to subpoena, hack, or leak. The signal Halo reads cannot be converted back into a picture of your family.
No image is ever created. Nothing to hack, subpoena, or leak.
No audio. No voice. The hardware doesn't exist in the device.
Radio signals, not surveillance. Physics protects your privacy.
Your health data is locked in transit and at rest. Always.
We make money from subscriptions, not your data. Full stop.
