Ducl Duplicate Photos Cleaner

On first scan of all images, it missed a lot of known duplicates - less that half, maybe 1/3. I then duplicated 2 photos 3x. In each of these groups of duplicates, I slightly cropped 1 of the photos. I scanned all photos again and none of these photos showed up in the results whether I moved the similarity slider to 60%, 70%, 80%, 90% or exact. What’s worse is that it has particular difficulty with any, mostly white, photos of documents even in “exact” mode. Some groups had dozens of very different documents. In checking other similar groups, I found some of the same documents as the first group i.e. the exact same documents were in several groups, but not in the same group. The app fails at it’s most basic functions.

Doesn’t work

I chose all the pictures I wanted and pushed clean but nothing happens.

Just downloaded the app today and when I try to scan pics , it crashes .

It’s not doing anything.

I love this app I’ve tried a couple of different ones they all wanted to charge a crazy expensive price to use it this one so far is been free and works amazing

Looks good, but “clean” button does nothing (yes, I checked the recently deleted photos)

Scanned photos, selected ones I wanted to delete, and then pressed "Clean". Button doesn't do anything.

This app is not working , i made a purchase but it did not works , crash and can not delete the selected photos , ios 13.3 i would like to have my money back please

This has been one of three duplicate cleaners I use every couple months to clean out my photo library. It catches things others don’t catch and it’s variable similarity slider has been very helpful. My biggest issue with the app is that if I try to clear too many duplicates at once, it hangs, so I have to clear in small batches. Unfortunately, today it stopped working. I was cleaning some duplicates. I did a batch and on my second pass, the Clean button stopped responding. I tap it and nothing happens. I tried uninstalling and reinstalling. I paid for the app because it was so useful, but now I don’t know what to do. It just doesn’t work. A real bummer.
