I downloaded the Lo-Mob app for my iPhone 4s few months ago, but have not really used it yet, until now. I played with it by shooting my Olympus OM-1N and some boxes of Ilford black and white film in the background. Focus was on the word “Olympus” and look at the bokeh produced. Not bad at all. I then applied one of the black and white filters that comes with the app, 30’s Contrast 2. It has a slightly hazy and vintage black and white look. Love it!
