Here you go @lloydy2410. I hold the iPhone in my hand as I run using #nikeplus running app. The treadmill said I did 3.2km but the app says 4.01miles. So there might be a problem with the accelerometer in the phone? Maybe I need to do a run outside and see if it’s different? Unless, I really have become an Olympic athlete overnight?! But this is unlikely brother… Lucie Kerley3 April 2013running, fitness, health, we own the night, nikeplus, girl, iphone app, run 2 Facebook0 Twitter LinkedIn0 Reddit Tumblr 0 Likes
