Calculator Pro

Great app, a staple on any device. Simple to use, and the cost to get rid of the ads was worth it. Kudos to the developers.

For those who havent tried the app, in portrait mode, it does all the normal arithmetic operation expected from a high end hardware calculator, then, when rotated to landscape mode, it does trig, square root, all the angle related operations.
I use this app all the time, it sits on my home page.
