InstaCalc is a vision for a fast, simple and powerful calculator. InstaCalc makes your life easy. It's a refreshingly different calculator that is simple, fast and surprisingly fun. It's called InstaCalc for a reason: answers appear as you type. Your time is important, the computer's time is not. Spend less time waiting, more time doing. Normal calculators and spreadsheets make you type and press Enter. Change the numbers, press Enter. Change the numbers again, press Enter. Why this extra step? Imagine having to press "Enter" every time you typed a key in Word. Decades of spreadsheets and desk calculators have conditioned us to tolerate this pause between entering numbers and getting an answer. Break free.
