Tried them all

Tried them all and if you are training this is by far the best of the best. I have used this app for years now and never been disappointed.

Its as accurate as the iPhone can be. The app is solid!

If there is a problem or question the company replies RIGHT back. The programmer actually uses the app and knows what his demanding customers want.

It has all you can need for running a marathon. I dont do all the other stuff but the programmer does so it works!
