Inaccurate
I remeber when apps were 99 cents. I think thats what I paid for the Nike app. I quite using the Nike app as it required sharing of information. Thats why I bought iSmoothRun. But it seems that dispite the extra money they want, for potentially nefarious reasons, access to auto updates (independance from the user) and access to to the Apple fitness app. Further I have found its distance tracking incredibly inaccurate. Nike was at least very accurate. I will drop my use of iSmoothRun. If you value privacy or accuracy I would not recommend this app.
