My Photo Stop is an IOS app developed by Jonathan Ross that is specifically geared for the landscape photographer that helps you find the best photo locations around you. You can upload your own locations for other photographers to find as well.
Each location will show sunset and sunrise times along with how far away the location is from your current position. If your photo is not geo-tagged, no worries, you can choose the location within the app by searching points-of-interest (Rocky Mountains), entering coordinates, or by just choosing the spot on the map where your photo was taken.
Each photo will also show what camera settings were used when the photo was taken. (Meta-data must be embedded in the photo)
Open the app often and new locations are added frequently!
