Needs updating Doesn't work too well on Lollipop. Will get a better rating when updated.

Simple and effective but.. My filter is labelled as ND4, but in your app I think it is listed as ND0.6. This is a bit confusing. Other than that confusion the app is very usable and does it's job well.

Nifty app that would benefit from a little Human Factors update This is a small, quick and usable app. There are 2 suggestions I would make to the author for improvement based on my expertise in Human Factors Engineering and Human Reliability Analysis. 1. As photographers we all work in stops and the app does show stops for all filter factors. However, there are 2 ways ND filters are specified by filter factors of 0.3, 0.6, 0.9, 1.2, etc. which equates to 1, 2, 3, and 4 stops of exposure reduction. Some manufacturers specify their filters with a filter fact such as ND 2, ND4, ND8, ND16, ND32, etc. which equates to 1, 2, 3, 4 and 5 stops. It would be helpful for some to have this filter factor specified in addition or as an option that could be set. 2. The other issue is more fundamental. The app shows a scrolling list of filter factors side by side with a scrolling list of shutter speeds. My initial assumption was that you lined up the shutter speed with the filter factor and it would give the answer. However, what you actually do is tap the filter factor and tap the shutter speed. Unfortunately, the app doesn't show you which filter factor or shutter speed is selected in the list.
