Cicada.
Sense
The body is broadcasting.
Sense is listening.
A quiet home device that reads heart rate, breath, blood pressure, and presence — without touching you. Mounts under the mattress. No wearable. No subscription.
A disc the size of a coaster, listening from under the sheet.
BedDot is the first Cicada Sense device. Slip it under the mattress, plug it in once, and it begins reading the room — your heartbeat through the springs, your breath through the frame, who is in the bed and who isn't. Ballistocardiography, done quietly.
Six readings, every second, without lifting a finger.
The data your watch can't get — measured straight from the mattress.
One app. As many sensors as you want.
Pair a device in under a minute. Add more as your house grows. Each one shows up as its own card and its own data stream.
One app, every body in the house.
Hover a feature to preview it. Rooms grouped by who's allowed in. Alerts triaged so only the things worth waking up for actually wake you. iOS, Android, and the web — same data, same consent, same household.
- 01Daily overviewOne glance answers: did everyone sleep well, who's home, what changed overnight.
- 02Vitals & trendsHR, BP, breathing, HRV — sparklines for the week, drill-downs for the year.
- 03Per-person profilesEach body in the house gets its own thresholds, baselines, and quiet hours.
- 04Rooms & sharingGroup sensors by room. Bedroom stays between you and your partner; mom's room can be read-only for siblings. Every share is a revocable token.
- 05Things worth waking up forSense triages itself. Routine readings stay quiet. Anything that crosses a threshold you set pings you — and only the people you've trusted with that room. Escalate to a sibling, a doctor, or 911.
No camera. No microphone. No surprises.
Want to earn from your data? You can.
Ethos is a separate, opt-in marketplace. Sense never sends data anywhere by default — not to Cicada, not to anyone. If you choose to connect, you pick the exact streams, approve every study one-by-one, and can pull the plug from your phone at any moment. Try the toggle above ↑
Raw signal never leaves the room.
