I don't have a fitness device as I use my phone (for budget reasons). I can't understand why the TP app doesn't allow for recording of activity in the way apps like Strava do. Unless I am missing something, it looks like I have to either by a device (not going to happen anytime soon) or manually upload runs and rides etc. (also not going to happen). Seems like an unnecessary extra step to me. I'm not a pro athlete and am very busy, so I like things to be as simple as possible, with as few steps as possible. So unfortunately, this might not be for me - shame really!
