iPhone 7 + latest iOS I would like to be able to hand change the gps locations in some of my photos and downloaded the app HoudahGeo, having read briefly that I could but I cant seem to figure out how and I would prefer not to have to jailbreak the phone to accomplish this task. I am aware that I could turn off the location in my camera but I am specifically interested in changing the locations of photos I already have and in future be able to do this again, if it is fairly easy to do. Is there a fairly easy method of doing this that I am not seeing or even another app that I can use. I have a trial period with HoudahGeo but unless I figure out how to do this, I wont have any other use for it. Thank you.
