Now, it’s top notch! – Analogue - BW Darkroom Review

Revamped my rating because author fixed the issue. It’s really “the” go-to black and white camera app for iPhone, in my humble opinion. Really a pleasure to use! However, the small format viewfinder doesn't match up (to be able to view your subject correctly. This is on iPhone 6s Plus.) And, you're unable to (see) the shutter release button (Again in small format/iPhone 6s Plus.) So, you have to tap around until you find it. I contacted the author and had a brief discussion about it and told him it must be an iPhone 6s Plus issue, but never received a reply after that; nor has there been a fix for said issue. If there were fixes or even a reply showing concern with the issue, I would rate it higher.
