Calculator Daily Ui 4

Day 4 of the 100 day UI challenge! Calculator. I am definitely in a burnt Sienna mood today, lets call it the old shoe leather calc. A couple things I did... The new iPhone is pretty tall and your thumbs can only reach so far! So I have shorter buttons on the bottom of the screen and taller on top. This will make it easier to reach the top row and your thumb will be less accurate, so you get more button space. I colored the 34 to represent the thousands place... This could be done for millionth, etc. Not sure how useful that is. Id need to test it.
