Description

Sum is a beautiful calculator with such visual refinement that it allows you to forget it -and focus on the numbers themselves.

It shows you the answer without you even telling it to. It shows you everything you need in a single page: No menus, no hidden buttons. Everything is a single tap away.

It calculates square root, nth root, 2nd power, and nth power (trig functions coming soon!) While still maintaining a sleek, simple interface.
