I once bought a step counter, with a separate heart rate monitor, and it provided lots of interesting information but I never used it. Despite my investment in the technology, it was simply too messy to use all the different devices in addition to my phone.The value of the additional information about my health was probably enough to motivate me, but the disparate technologies prevented me from using them. Today there are step counters and GPS in our phones, and heart rate monitors in our smart watches. With a simple app download you have everything you need, all through devices you already use and bring with you everywhere. By consolidating these technologies into a single device it is now practical to access the information on my health that they provide.
