actually a very good little app – Sunfollower - Sunrise, Sunset, Sun Position Calculator Review

suprisingly good despite some of the odd reviews one thing i have noticed, especially when using the camera view mode is you need to give it time to settle in - it will not be spot on ever, but gets pretty close in putting the sun where it actually is in the lense....
