Soulver 4

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.

Because Soulver uses sheets (like Notes), you can explore different ideas: weigh options, change variables and watch everything update.
