In addition to amazing backgrounds, Calcoid boasts better-than-human-brain familiarity with trigonometric functions, degress/radians, exponentials, logarithms, and percentages. The app's free version is ad-supported and limited to a single background, while paying $0.99 will unlock all available backgrounds.
Although its looks scream "iOS 7", Calcoid is made exclusively for Android and its developers plan it to stay that way. You won't be getting a prettier calculator app in the Play Store anytime soon, so go and get it right away.
