I don't really understand this app. I'm not sure what it's trying to tell me, lol. There are no instructions, although I shouldn't need them. It's just a simple formula. Why all the extraneous stuff? I found a much simpler calculator that gives you either the distance if you enter the aperture or it gives you the aperture if you enter distance. The only other thing you enter is the flash's guide number and the ISO.

Relatively new to flash photography but in my rather limited experience 8 know the distance of the flash to subject it's the power setting for the flash that's variable. I realise you can move the sliders to get the distance you want but wouldnt it be easier to set the distance as a fixed value and have the flash power as the variable?
For the price, this app ticks all my boxes. Well done. I use it with my medium format SLR film camera, primarily for macro or near macro. Suggestions? Since MF or LF lenses tend to have rather tiny minimum apertures, e.g., f32 or f45, I'd love to see these two f/stops added to the aperture range slider. Even better would be some sort of extension factor, i.e., additional stops needed based on length of extension (tube or bellows).
