help Emfit QS3 FAQ
How does the Emfit QS3 track sleep without a wearable?
The Emfit QS3 sits under the mattress and uses ballistocardiography to detect tiny body movements. It can estimate sleep-related measures such as heart rate, breathing rate, movement, and sleep stages without a wrist device.
Does the Emfit QS3 require wearing a smartwatch at night?
No. The sensor is installed beneath the mattress, so the sleeper does not need to wear a watch or chest strap.
Can the Emfit QS3 track two people in one bed?
The QS3 is designed around a single person's signals and is generally best used on one side of the bed. Couples should check the specific sensor placement and app support before treating its readings as individual data for both sleepers.
How does Emfit QS3 data reach the phone?
The QS3 sends recorded sleep information to its companion smartphone service for analysis. It is intended for overnight monitoring rather than a handheld spot check like a pulse oximeter.
