Why are bands scaled?

The wemo was originally inspired by a nurse who was seen consistently taking notes directly on the surface of her hand. We wanted to give that nurse, and others like her, an alternative way of jotting down notes quickly on the go, without affecting the skin.


The measurement markings on the band were also inspired by the tools that working professionals require to have close by throughout the day.
