Black
It's true: every photo app on your phone can handle black and white conversions. Hell, some are built into iOS itself. But none of those tackle B&W quite like Black. Built from the ground up to emulate black & white film, it uses carefully analyzed and reproduced films from the likes of Fuji, Agfa, Kodak, Ilford, and others to recreate the effects of those classic rolls on your own photos. In addition, it offers built-in vignette, fade, and curve controls, ensuring that your monochrome masterpieces look just right without the need to fire up a second app.
