While Im not a professional photographer, occasionally I do paid work and take photography seriously even when just using my phone. I have also owned dozens of photo apps over the years and this is the only one that has survived the test of time.
I have done testing trying to replicate in other apps what Noir Photo can do and nothing compares to the elegant processing and smoothness it creates easily.
It is a must have if you are into B&W photography.
