Is there an app for that?

Hi all, question for you folks who have been shooting nature for a while. Is there an app that will tell me exactly where the sun is in relation to where I am?
Reason I ask is, I like to know where the sun is so that I can get the most out of my shots when its overcast. And sometimes, even when its not overcast, but there are clouds out, I have a hard time determining where the sun is going to come up. This may seem like second nature to you all, but it stumps me every time!

Hello there, my first post on my first day here.
You dont say what phone but the app is a Photographers Ephermeris. The Android version was expected any day to go along with PC, iPOD and maybe others. Just goggle those words and your phone OS to see whats available.

Marie,

I love to use Stellarium

It's a great little program
