PhotoFiler is meant to allow you to tag and store your photos in a searchable catalogue.
It would be most useful for any photo which you would like to find easily again, without having to scroll through your whole camera roll.
PhotoFiler also comes with a built in feature for remembering the location of any photo taken from within the App. The approximate address can also be gleaned from the photos location.
You can share a screenshot of your photo record, as well as share the location and the address through WhatsApp.
The date and time the photo was taken is also stored and photos can be sorted either by name or by date.
