I've been using the map my walk app from under armour. And while i thought it was good, i recently tracked my mileage around a school track, and it measured 6.7 miles, when i only did six. That's quite off.
On another occasion, i did 3miles and it marked 3.4. I'm just trying to find another app that is more accurate.
