I was shooting with my pinhole camera and some exposures required exposure longer than a minute. I was finally able to use https://itunes.apple.com/us/app/reciprocity-timer/id459691262?mt=8
It's a really an amazing app for calculating reciprocity failure with film. I shot some old 4x5 Fp4 and semi-stand processed it. I looked at the shadows to check on the exposure and it seems to be spot on. The best part that it's a free app. If you bought the paid version, you can store your favorite films. I wonder how the author got the information on the various films?
