Quick question (bare in mind I am yet to receive my Apple Watch and have never used fitness apps, so if this question is stupid/has a obvious answer then I do appolgises). Will the Workout app work when you use a Exercise bike? The problem is I have read it uses GPS to track your location and movement but obviously you don't move on a bike. If I left my iPhone in my pocket will that contribute at all? Side Note: Just started using one too day and have yet to look for a app to go along with it, so if anyone can recommend one that will be great! I stupidly left my iPhone on charge so it didn't even track my workout us the M8 processor! Thanks in advance, Alexandros.
