ND filters are pretty much irrelevant considering the long exposure live photos coming to iOS11.

The results are pretty impressive, but I've backed projects like this before only to have my next phone make the filters obsolete or no longer fit. I like the clip design here, but I feel like I've just been burned too many times on this kind of solution... :\

Looks cool, but really, for 49 you can even buy a camera filter.

I feel like this will be a nice market for those who do not necessarily need a nice phone but want to hand a new feel to it. In my case, this would be a great present for my parents as the camera is exclusively what they use. Will look into backing this!
