I just released Arithmate Pro Calculator to Google Play! 
It's a modern, advanced calculator which unlike most of the already available ones displays the whole expression you're inputting in a beautiful (LaTeX-style) way. This makes it easier to spot and correct errors, ensuring that you get the right answer.
It supports trigonometric and logarithmic functions.
I'm currently working on speed optimizations and a viewable history.
Any feedback and thoughts are welcome
