Overview
A smart sock worn on the baby's foot sends readings over Bluetooth Low Energy to a base station, which joins home Wi-Fi so sleep data can be viewed from anywhere. One base station supports two socks for twins.
Remote viewing and twin support are the reasons to look at it, and the Bluetooth link is described as low radiation. The limitation is setup: the base station needs a private Wi-Fi network, the Bluetooth link reaches a limited distance, and no sock size or medical claim is given.
Who it's for
Parents who want sleep, movement and heart rate data on the baby, including families with twins, are the audience. Households without a compatible Wi-Fi setup, or those who want a medically certified device, should look at other products.
Pros and cons
- Tracks heart rate, movement and sleep
- Remote viewing from anywhere
- Supports twins on one base
- Low-radiation Bluetooth link
- Needs private Wi-Fi for the base
- Sock size not listed
- No medical certification stated
Performance notes
Readings travel from the sock to the base station over Bluetooth Low Energy, and the listed range applies in open space, so walls and other obstacles shorten it. The base station then forwards data over home Wi-Fi, so a weak router limits remote viewing. The maker describes the Bluetooth link as emitting negligible radiation.
