MetaX

The editing is a little clunky, as it asks you to delete the image you think you are saving. It may be that the app is making a copy and you edit the copy then delete the original while saving the copy with the same name.

This app would be amazing (not design wise, just because it’s the only free app that doesn’t add a watermark), but it only edits the “created date” not the “modified date”, and camera roll sorts by modified date, so if I use this app to say a photo was taken in January 2001, it will still be the most recent photo in my camera roll, which defeats its purpose for me. If all you need to change is created date though, it works fine for that, as long as the date is in the past.
