From the makers of HDR Darkroom 3

I used HDR Darkroom 3 on my mac and the presets on this app had the same icons. Turns out its the same company...

Its a pro HDR app, takes stunning HDR pics out of only 2 exposures (under and over) which limits the chances of having alignment problems and ghosthing.
