Got some disappointing news today concerning my new retina mini. One of the features I was looking forward to was using the included M7 motion processor chip. This is designed for applications such as motion tracking, fitness monitoring, etc. There are now several apps available to address these kinds of functions. Downloaded a highly rated one today called "Pedometer++". It installed just fine. But when trying to run it got an error message saying "this app requires a device with a M7 motion processor such as an iPhone 5". I had assumed that the retina mini and Air should support this application since it has both an A7 and a M7. Did some digging on the internet and found the following note: "Though the iPad Air has an M7 chip, it does not report step counts and is not compatible with Pedometer++ and other M7-enabled apps." This is a total bummer, as I had anticipated using the M7 capabilities. Not sure if it is a hardware or firmware issue, but it sure looks like I'm out of luck. Thought I'd pass this along in case others were thinking of purchasing a retina mini or air for this type of usage. Guess there is an outside chance that iOS7.1 might help but I'm pessimistic. Does anyone have thoughts about how this limitation might ultimately be resolved?
