From Kobot Software :
Photo Radar is for those of us who are continually finding interesting locations to shoot while they're out and about - but never when they have their camera gear handy.
With Photo Radar, that's no longer an issue. If you see a shot worth taking, use Photo Radar to tag and mark the spot on a map and save a quick preview shot for later. Next time you're looking for something to photograph, just check what locations you've saved and bring an interesting one up on the map.
You can also send links to saved locations via email - whether you're trying to help a client find today's shoot location, or just want to point out an interesting spot to a friend, it's all easy with Photo Radar!
