Sums is the new super intuitive gesture controlled calculator.
Making maths fast easy and fun!

Sums uses multiple gestures laid out like petals of a flower to make performing maths operations a much faster and more intesting task than with standard calculators.

With large easy to tap main keypad, sums is specially designed so it can be used one or two handed. All the standard maths functions like add, subtract, multiply and divide; are easy to access with a simple swipe gesture, and negating the current number quick and simple by rotating the device face down then back.

Calculations are recorded and can easily be reviewed with a downward gesture, and easily cleared by dragging the last item down or simply shaking the device from side to side.

The delete button is also special, as you'd imagine you can delete a number or decimal point, but it also lets you delete previous operations, so you can go back and edit the number you just entered. Its very easy and extremly practical, and works all the way back to the first calculation on the list!

In the full version there are gestures to access a memory store, so you can quickly and easily save important numbers and recall them at a later date, and and advanced scientific menu containing all the common trigonometric and arithmetic operations you need.

We've taken a lot of time to design and polish Sums so its an easy to use and fun experience, we hope you enjoy it too...
