Great!

At just 1.4MB, this app is punching well above its weight. Congratulations!
And its high contrast makes it easy to use in bright light. But that brings me to a minor criticism: the colours are a bit intense - especially the blue. I realise that subduing the colour scheme will probably increase file size but I think making it easier on the eye would improve the user experience.

Great app

This is a great calculator app especially for programmers. The hex functions are perfect. I couldn’t find the parentheses at fist but they are there when you press the “2nd” key. I like it so much I am purchasing the pro version.
