Works well – Exif Editor and Viewer Review

I edited a photo, changed the date fields (all three of them), and the photo showed up at the proper position in the "moments" timeline, reflecting the date that I had set. The one field you can't change however, is the TITLE of the photo - so in the "camera roll" section of the photos app, the photo will appear wherever it first appeared when you first added that photo to the camera roll. That's because in "Camera Roll" the photos are sorted by their names and every time you add a photo to it, by whatever means, that photo gets a new name, namely, the next higher number than the photo before it. In "Moments" however, the photos are sorted by date and this app allows you to change the date (along with a whole host of other metadata) such that the photo will then appear in the timeline that you set for it. I have not yet experimented with gps data.
