PocketCalc

PocketCalc keeps three everyday jobs behind one screen. The calculator works the way your hand already expects — one entry at a time, operators applied as you go, big round keys that are easy to hit. The converter takes a single value and lays it out across a whole family of units at once, so a length in metres shows up in feet, inches and miles together, and Celsius, Fahrenheit and Kelvin sit side by side. The tip splitter turns a bill, a tip percentage and a number of people into the amount each person actually owes, no napkin math required. Everything is a tap away from the home menu, the look is bright and uncluttered, and nothing gets in the way of the answer.
