What is Hubble Guardian+ device?

Hubble Connected is thrilled to introduce Hubble Guardian+! This sleek, wearable device allows you to track your baby’s heart rate, oxygen level, body temperature change, and movement from the compatible smart device.

Guardian+ is designed with a soft fabric strap that is easily adjustable to provide a comfortable and secure fit on your little one’s ankle. When it is time to charge, remove Hubble Guardian+ and place it on the charging dock, which also serves as an audio monitor and relaxing baby soother. Control all features that Guardian+ has to offer with the HubbleClub app. This app is also utilized with our smart Hubble Connected baby monitors so that you can control your entire monitoring experience under the same ecosystem!
