100 Days of UI Day #004 Calculator

Day 4 - 100 days of UI - Calculator

I stopped doing these because I got crazy busy with life things. Back at it though so here is the rundown of my decisions for this one.

I wanted to keep it pretty simple as well as add some things that I don't see often or at all on an iOS calculator. That being said there is a small history on the top right side to be able to easily move back to a previous step in your calculations if you made a mistake, and the percentages are something I added for this to be something for sales people/account executives to add margins into their estimates immediately while in the field. I though this would be a cool feature and if it ever went to being an app the percentages would be customizable in the settings to be whatever their most common markups are when estimating.

Feedback appreciated, thanks!
