Works as advertised and very clever

This app saved me hours during my transition from Aperture to Lightroom. It does a fantastic job of finding not only exact matches, but “similar” photos with incredible flexibility on what “similar” really means. That means you can find those dupes of different size, or even different formats (i.e. a TIFF left over from Nik + the original). It is rediculously fast for what it does. It beats the LR plug-ins due to the convenience of the comparison / review tools and the ability to then quickly accept or change the auto-markings (with great parameters for logic). I’d add a couple of things, like better ability to highlight bracketed shots as non-similar, but these are tiny gripes.
