Mainly aesthetic for the other scientific calculators available. I wouldn't mind putting my photoshop skills to use for better coders. I also don't like RPN calculators (I think yours) but I love your UI and haptic response. Awesome. I just don't know how to use an RPN calculator and it seems very complex. Tiny numbers.
And icons are a biggie for me. Yours (and this is constructive) appears like a cutoff picture as opposed to an icon specifically for the phone. My background is mainly front-end design, hence the pickiness there.
