Ever reach for a calculator and the back of an envelope to work something out? That's what Soulver is for.
It's a natural-language notepad calculator: think through a problem line-by-line, using plain words and numbers. The answers appear alongside each line as you type.
Soulver isn't just a calculator app — it's the paper you'd scribble on to figure something out. Except this paper does the numbers for you, so you stay thinking at the level of your problem.
