Exiftool and iOS

[thatkeith]

I've been having fun making a tool for Mac OS and Windows that edits panorama-specific metadata, using the exiftool command-line app.
Is there any way to use exiftool in iOS (and/or Android)? Is there any LC-accessible way to edit the metadata of an image in a mobile OS? Am I being exceptionally* dim to even ask this?

(*As opposed to just my normal level of dimness...)
