Fast But Wish It Had Another Feature

Very nice app. Works a lot faster than Gemini and PhotoSweeper. However, it does not have an option for moving duplicates to a folder instead of trash. That would have been really nice to have.

Removes from Folder Does Not Delete

I bought the Pro version thinking that it would work better than the free version. I wish I saved my money. I does find similar photos very quickly but you have to watch for "duplicates". They may just be similar photos. Auto select isn't the best bet.
After all of that all of the duplicates I had to go through were placed in a "duplicates folder" where you are supposed to select and delete.... Well that's not an option. You can remove the pictures from the file but cannot delete. You can delete the folder but you will still have duplicates. After another scan from "removing" the photos; they are still there.
I would like a refund, actually unless you guys can figure out what is going on here.

Excellent App for Complex Work

I used the trial of this app to test its ability to handle about 60K worth of pictures that had some levels of duplication, due to them being moved, to and from various cloud storage locations, and my attempts to sort them at various times over the last 10 years.
This application made the removal of dups possible!
The user interface is spot on for this type of work.
Well done!
