Looking for a bit of advice please. At the moment I'm using Runkeeper on my phone, I like it very much but it does mean carrying (obviously) a phone and it's sometimes a bit hit and miss. I particularly like the maps it creates, but already my phone tells me it's memory is full and I'm not sure how or what to delete...I have a watch for swimming and really like it. Now I'm thinking about buying a running watch or some other type of device for running. Any advice please? Anyone tried both watch and phone apps and prefer one to the other?
