Sum-o is a calculator, a clever beautiful calculator. Its interface has been hand crafted to enhance your experience using the full capabilities of the latest iOS. Sum-o is versatile; it reacts to on-screen gestures and device motion.

Our favourite feature is the background which constantly and dynamically changes depending on your calculation. Warm colours indicate a positive answer while colder colours are displayed as negative.
