How to measure how far I walk?

Is there an app for the iPhone? I would really like to know, for fitness reasons (I'm not fit.)

There's a little devise called a pedometer ( sp? ) that you wear on your belt, that measures how far you have walked.

You can get the free app "Endomondo", and it has functions for both running and walking (among others). I'm not sure how entirely accurate it is, but it's a great start.

IPhone health stock app already measures steps.
