Only app that worked without crashing
In January 2020 I tried all the duplicate photo remover apps available for iPhone, this was the ONLY app that could handle processing over 60,000 photos in a batch without crashing and produce usable results—with no advertising or annoying pop ups— including identical duplicate photos, gifs & videos, or nearly identical images to eliminate similar images. I found nearly identical sets to be the mist useful thing about this app, helped reduce multiple pictures of the same subject matter. Thus is one of the few apps that showed percentage of progress as it analyzed, unlike most other apps that just had a spinning wheel that gave no indication if the program was hung up after an hour or more of analysis. All other apps crashed at some point despite multiple attempts with each app. This app analyzed over 60,000 photos in 10-15 minutes, and automatically updated results if you un-deleted previous matches or added new photos. My recommendation is to use this app in conjunction with your phone’s photo app: because, even though you can view each individual file of match sets at nearly full screen resolution and pick one—or multiple, or all—files in individual sets to delete, you can’t enlarge the photos to scrutinize details, and it doesn’t animate gifs/videos so you can’t tell if one item in a match set is a photo vs a gif, so my advice is to delete all duplicate sets then sort them in the deleted photos trash bin in your phone’s photo app where you can enlarge, flip between items to scrutinize, and determine whether items are gifs vs photos matches, and then recover the individual items that you want to keep.
