Nice Try, for sure, but found this very difficult to use
This seemed almost impossible to practically use. I'm a bit of an armature photographer, so this might be intended for a deeper background. I have been an avid photographer for ~45yrs (so I'm not new to this), and am an engineer by training. So I'm also not daunted by the concepts, math, or technologies. I also found the app a bit buggy - would periodically hang up. I also found it very difficult to use on an iPhone due to size (for which I was forewarned), but have also installed it onto an iPad with no better results. Great try, for sure, but in a practical sense I didn't find it was going to be useful.
