New version is great! Photos app support!

This version is great. It’s easy to use, very well explained, with tutorials inside the app, and it works as promised.

The auto mark features are smart enough to decide to exclude lower resolutions, lower DPI etc (you can customize plenty of options!) and it separates all photos in a duplicate album so you can delete the ones you decided to mark.

I spent a lot of time searching for something like this and this is the only app which can check for duplicates on the Photos app in a timely fashion (I found another one which is more expensive and takes 6 hours to mark 600 photos as duplicates, and even failed midway! This one did the job in 6 seconds. Highly recommended.
