The iPhone 6 and Apple watch gathers an awful lot of data about me and my activity but how do I analyse this data? the iPhone health and activity app is pretty much useless for any sort of serious analysis. What is needed is a a OSX app so you can see decent sized chart data and the ability to construct a proper query on the data. I can't see anything like this on the App store - anybody know of anything? I just downloaded Lark for my iPhone but it was so stupid it could not even recognise that a recorded indoor run on a treadmill counted as running activity.
