Vibrant Calculator

Customize your calculator by choosing button shapes, colors and text colors. Set one look for the whole keypad, or style each key on its own. Pick a shape, a key color, and a text color, then drag keys to rearrange them. Save a layout and come back to it later. The calculator opens with the last look you used. Start from one of ten templates: Rainbow, US Flag, Texas Flag, Sunset, Ocean, Midnight, Forest, Neon, Pastel, and Christmas. Turn on the scientific keypad when you need more than basic math. It adds sine, cosine, tangent, and their inverses, logarithms, roots, powers, parentheses, pi, e, reciprocal, and factorial. Switch between degrees and radians. The keypad fits the screen on iPhone and iPad.
