Is there a duplicate finder for Yosemite OS Photos and Documents?

[iMore Question]

I have searched the internet. Found Gemini, but it does only iPhoto and not Photos - I have confirmed this after I read it in the comments.
Want it to be an app where I look and decide whether to delete a duplicate.

'Photos Duplicate Cleaner' is available in the App Store and is compatible with Photos and iPhoto. I don't have any experience with the app myself, but it does have a 4+ rating at current time. Good luck!

There's Duplicate Photo Cleaner. It has a mode for Photos and a mode for iPhoto if you need it and can find duplicate photos and similar photos too. Also Easy Duplicate Finder has a Photos mode.
