Soulver 2.0

Soulver helps you work things out.
It's quicker to use than a spreadsheet, and smarter and clearer than a traditional calculator.

Use Soulver to play around with numbers, do "back of the envelope" quick calculations, and solve day-to-day problems.

Just type your problem as you'd write it on paper. You see your answer instantly. No setting up formulas, no equals button. If you make a mistake, you don't have to start all over again, you just hit delete.
