For the lucky few that got their little paws on an Apple Watch, I have a couple of Q's, anyone who can answer them will forever go down as the king or queen of awesomeness in my books. 1. How accurate is the app(activity), heart rate monitor and general information gleaned from iPhone GPS, steps etc? 2. As I understand it, there's an indoor cardio bike workout option on the watch/app (correct me if I'm wrong) how accurate is this? As I train for charity bike rides around the UK/Italy and I find strapping on heart rate monitors etc are an unneeded hassle; does it count calories burned fairly accurately? Many thanks for anyone that answers, enjoy your watches!
