About Soulver 4

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. 20% of $1,480 | $296 $100 in EUR | €86 240 km in miles | 149 mi $1,200 + 15% tax | $1,380 3 weeks from today | June 21 Because Soulver uses sheets (like Notes), you can explore different ideas: weigh options, change variables and watch everything update.
