using for duplicate photos deletion

Instead of deleting duplicates one at a time. Is there a way to automate the process? Its going to take me a long time to go through my entire photo library. Some of them have 5 duplicates per pic.

apart from that, the app seems be working ok and i am not having any problems like some of the other reviewers. Using this on Big Sur with a 2015 iMAC

Developer Response ,

Do not waste your money with this app!! JUNK

I initially downloaded this app from the app store, and purchased the $9.99 upgrade within the app because without it, there is not much you can do. This app completely messed up my MAC book pro. I lost a large portion of my iTunes music library due to using the Clean iTunes junk feature. It messed up my pictures as well. Even though this app is in the app store for download and purchase, after talking with apple, they do no recommend programs like this. Don’t know why they allow it in the app store. If you want your computer completely messed up. go for it. It does what is says, but it removes everything. Thanks to apple and my time capsule, I was able to restore my music from a previous backup.
