  • Great App

    In approximately 97 to 98% of cases, the app is very efficient and precise, correctly detecting identical or different from each other only in terms of details such as slightly different resolution or color depth duplicates, when its Similarity threshold is left set at the default 80%. However, there is approximately from 2 to 3% of cases when PixCompare puts nearly identical photos into different groups in Grouped view, not juxtaposing them all together, so that even if you remove some of those nearly identical photos from one group, the same such photos are not compared and may be overlooked and mistakenly left in other group. All in all, then, the app is great, and would be perfect if it were possible to improve it by making it compare to one another all of the nearly identical photos fitting under the Similarity threshold set, and not leaving out some of such photos

  • For Me The Price Is Worth The Experience

    True, it doesn't work very well. Frankly, I'd be willing to pay 10 times the price if the app was brought up to useable standards. I applaud the developer for this creation... The description is clear regarding best performance for photos. My wife had a box of over 100 old 1900s B&W negatives from her ancestors gold mining and other businesse In Silverton, Ophir, and Ouray, Colorado. I found a guy who charged a reasonable price to create digital negatives and images. I ran the folder through this app and it listed many duplicates. Luckily, I was cautious and looked at the image types being compared. We were provided with RAW files, Tiff files, and JPG files, to allow the best choices for my wife's projects. I ran a myriad of other image files through the program and less than 1% actually matched. Actually, just viewing the images allowed me to choose many to simply delete.

    I've been using Pix Compare for years. Its had its ups and downs until, with its initial AI implementation, I finally set it aside. Tried v7.3 and its now quite excellent. Still not the quickest but now the best of the 3 image comparison apps I use.

  • Fair Accuracy -- should use Touch Bar

    Right out of the gate I was surprised at some of the false positives it returned. So far I have not figured out a way to compare the contents of two folders against each other, rather than finding dups only within a single folder (and its subfolders). The side-by-side (list) view is very useful, particularly with the ability to see the file path under the picture and also easily open the image's containing folder (reveal in finder). After a scan is complete, I don't understand why it takes so long to switch between the "grouped" and "list" views.

  • Doesn’t work.

    Doesn’t work. A joke of a program. I put in photos that were only slightly different and it says they are very differnet and those that are very different it says are matches.

  • Great Accuracy - Needs More Speed

    I’ve used previous versions of this app, so I’m thrilled to see it back in the App Store with an updated version. It has great accuracy, certainly at least as good as PhotoSweeper. My main complaint is that it’s not very fast. Right now, I’m running on a multi-core machine, but maybe one core is really working as it loads files. PhotoSweeper clearly maxes out the CPU and gets results *much* faster. The matching algorithm is clearly more accurate than PhotoSweeper, but I’d love to see the two programs merge - the UI and speed of PhotoSweeper and the matching code from PixCompare. In the meantime, buy both - each will find duplicates the other one misses.
