I wish I could find more info on how Snapselect works. I'm looking for something like it, but I can't really find anything about how it identifies duplicates/similar images. Timestamps? Image contents? Something else? There's no demo version either.
I have some interest in the other apps, but perhaps not enough to buy the bundle anyway.
It analyzes the images. I use it and like it. It's not perfect, but it works well.
