Ok, I do love the app, and I am ok with the price of the dongle, and even the "subscription" model, but there is one thing that absolutely needs to be fixed. The app cannot and should not automatically shut off when the dongle is slightly dislodged from my iPhones dock. I have lost several full (or near full) workouts as a result of what can only politely be described as a "design flaw." Devs, please fix ASAP. I do have one minor other gripe. The weight chart. No matter how many data points I enter into the app, the chart does not change. The x and y axes are there, but no line graph at all. Ok, one more gripe. The music interface is sub-par. Why do I have to listen to a playlist? Why not just shuffle everything on my iPhone? Also, way too many button pushes are necessary to get music playing, and the buttons that do need to be pushed, like the "done" button in the far upper-right corner, are in awkward places, especially when the iPhone is in an armband. 3 stars for now, I will modify the review as updates are created.
