The Brave Lion

Encourages your little one to check up on their heart, with a little help of our Lion's brave heart


Lion, also a member of The Guardian animals family, has a different special power. While collecting vital signs he encourages little ones with his brave heart.


Hidden inside his soft heart is a sensor that measures heart rate, oxygen saturation level within seconds and gives information about Heart Rate Variability.


The Lion is made in Europe from carefully picked finest materials, to provide soothing and comforting experience for children and their parents. This soft superhero is machine washable so you can maintain his soft and fresh feel.


The Brave Lion, 10 inch high, makes a perfect huggable friend with super cuddly plush and matching satin mane, just like a real lion cub.

Special Power: Measuring heart rate and blood oxygen saturation, proving HRV


Our Lion gets his special powers from the electronic module connected to a mobile app.

The sensor and all electronic parts are safely placed in a plastic enclosure looking cute as a button.

Bring our Brave Lion to life by placing the CR2450 coin battery in the holder.

The accelerometer in the button will make sure Lion wakes up even with the slightest movement, and will also put him in the sleep mode when he’s not in usage.

The Button is wirelessly connected and sends all collected data to the mobile app.
