Iphone 5s

Within minutes of arriving home to an empty house, my phone started ringing. The caller Id told me that it was my oldest daughter calling, when I swiped accept call, I was startled to hear her out of breath! She quickly told me that she was in the forestry with her best friend and that they had just completed a 2 kilometer run. I was puzzled and also concerned, as she is not at all sporty and how the heck did she know that they had run 2 kilometers. It soon became apparent, she had downloaded an app on her IPhone 5s that tracks the distance and time of your run, to say I was impressed was an understatement! When I was younger it was all about estimating how far you had run by using landmarks as markers and as far as timing it a good old stopwatch never failed!
