Is there an app that I can use on an i-phone that will create a GPS log that I can then use to add GPS coordinates to the EXIF of my shots.
I know there have been threads about GPS data loggers that create a time stamped log of where you have been and third party applications that can take that log and a list of pictures and add GPS coordinates to the pictures based on the timestamps.
Now that I have an iphone, I was hopping that there is a GPS data logger that I could use for the same purpose. (My google searches are getting bogged down with apps you can put on your kids' phone, or cheating spouse, to find out where they are and where they have been).
Is anyone using an iphone for this purpose? How are you doing it?
