Just wanted to add that Nitro was built by Nik Bhatt, who was the Senior Director of Engineering at Apple leading the Aperture and Core Image teams. I believe he built Nitro specifically to fill the vacuum Apple left behind. Not sure how close it gets to the OG.

Yeah, I was on the Photos team when Nik Bhatt left Apple to start this project/company. So I suppose you clearly have Aperture DNA there…

shame I had not heard of this till today.

Also loved Aperture and also a shame this is the first time I've heard of this tool.

I’m a big fan of their Raw Power app as well that predated Nitro.

thanks for recommending that: i had not found it and also lament Aperture's retirement for years. Subscribed monthly to Nitro just now...looks great
