Crucial app for reading EXIF and for detailed viewing!

I use this app daily for two critical purposes. The first and most obvious one is to read EXIF data to remind me which app(s) I have used for a photo — so that I can correctly tag it before uploading it.
Less obvious, though equally valuable, is the ability to view an image at the highest level of detail — more detail than the Photos app allows. On my iPhone 5, this ability allows me to compare similar photos to check fine focus details. I use this feature many times a week!
