Best Mileage App with GPS

[emjayess]

I need some help finding the best mileage app for my iPhone 4S. I have looked at a few other threads, of course, googled the heck out of the topic. The problem is most of these apps do not use GPS and I DO NOT want to have to enter odometer readings every time I head out for the day (I travel to see clients daily). I just want to tap start and stop etc.

A PLUS would be if the mileage function was bundled with a more general expenses app for a small business/independent contractor, but I haven't found anything.

Thanks in advance for any help you can provide!
