.  I guess I stick with Runkeeper (on Android) because at the end of my runs all I need is how far, how fast, and about how many calories. So I guess anything would work with me. Although Runkeeper will do cycling too, which is nice.  I only tried nike+ ios app for 0 day or not, then I deleted it. It's pretty silly that it stops recording when the screen is turned off! I wonder why Ars does not mention this. I think Micoach is a better alternative.
