My favorite IPhone Features is the location tags it puts on pictures you take. It helps me remember where I’ve shot so I can revisit it or not repeat. I know there are more advanced ways of doing the same thing but I love that my phone does this on its own.

Some of the shots I took at these locations can be found here:
