Users can fine-tune Gallery Doctor’s bad photo choices prior to deletion. Everything is selected by default, with a trashcan icon in the lower right corner of each thumbnail; a tap removes the image from removal, or you can tap and hold to see a preview. Sadly, there are no selection shortcuts, so if you only want to delete a handful of images, prepare for serious finger gymnastics from repeated tapping.
Likewise, the “similar” review displays flagged images side-by-side, one as “best photo” and the other with a trashcan icon. While this comes in handy for burst mode shots, in my experience Gallery Doctor identified way too many photos that looked nothing alike.
And it gets worse: There’s no option to start over unless you go through all three review stages, at which point Gallery Doctor is supposed to get smarter with subsequent attempts. I wound up having to delete and reinstall the app in order to start fresh—this time with a gallery health score of only 32 percent, at which point I threw up my hands and charged this doctor with malpractice.
Gallery Doctor sounds like a promising solution for scrubbing unwanted photos off your iPhone, but users with larger collections are better off performing this kind of surgery the old-fashioned way instead.
