Made for real life

Signal Smith takes a different approach.

Less to do at bedtime. More to understand about your night.

Nothing to wear

No watch or ring to charge, remember, or put on at bedtime.

Not tied to the mattress

Contactless sensing is designed to work from across the room.

Designed with privacy in mind

Core radar motion sensing does not require a camera or recognizable imagery.
