“The wristband itself is superbly designed: The slight oval shape and rubberized case mean that it hews to your wrist without bouncing around, which would have made it into an annoying bangle. But the wristband is a minor part of the offering. The real product is the software, and the interaction experience. And that’s where things go wrong: The software is too buggy and confusing, the user experience too unresolved. But rather than carp on what’s wrong, I wanted to lay out a few lessons that the product’s shortcomings teach you about app design and user experience design in general. A product like this teaches us all how to make things better.”
