24 GHz Contactless Radar

Sense life.
Touch nothing.

Rabits reads heart rate, HRV, respiration and sleep from across the room. No belt. No electrodes. No wearable to remember.

Direct

Effort, not inference

Rabits measures chest-wall motion itself. An absence of breathing effort is a central apnea — full stop. No oxygen dip to guess from.

De-biased

Noise floor removed first

Every HRV figure has the sensor's own beat-timing jitter subtracted before it's shown — and is withheld entirely once that noise dominates.

Contactless

It sits with you while you work

Place the module in front of you and carry on. No belt to strap, nothing to clip on, nothing to charge on your wrist — it just watches the chest and stays out of the way.

See it work

One module. Three ways to live with it.

The same radar hardware adapts to how you actually spend your day. Watch it move through all three — or tap to skip ahead.

  • At the deskFacing your chest while you work. Heart rate and breathing, no belt, no electrodes.
  • At the neckOver the carotid artery, it records the shape of the pulse wave — not just a beat count.
  • Beside the bedOn a tripod, about a metre away. A full night recorded without waking anyone.

The hardware

A single 24 GHz continuous-wave radar module. Small enough for a desk, a tripod, or a bedside table.

  • 24 GHz CW radar — sub-millimetre chest-wall displacement
  • 0.3–0.8 m range — aimed at the sternum, through clothing and bedding
  • BLE to iPhone — all processing on device, nothing leaves your phone
  • No camera — radar sees motion, never identity

Send your night to your doctor. One tap.

Every recording saves as a plain file on your phone. Share it by email or message — no printing, no scanning, no portal to sign into. Your doctor opens it in whatever they already use.

On device

Nothing is uploaded

The night is processed and stored on your iPhone. There is no cloud account, because there is no cloud.

One tap

The normal share sheet

Email it, message it, drop it in Files. The same button you'd use to share a photo.

Open format

No paper, no lock-in

A plain CSV any clinician can open. Nothing to print, nothing to post, nothing to log into.

Health you don't have to wear.
