Summary
Soulver 4 is a notepad calculator app that lets you write calculations line by line using plain words and numbers, with answers appearing instantly alongside each line. It converts currencies live across 190 options, including crypto, and handles percentages phrased in everyday language. It also converts units of length, weight, volume and data, and calculates dates, time intervals and time zones. Sheets can hold variables that update automatically when changed, and results can be exported as PDF, text or HTML email. Sheets sync across devices via iCloud, and Soulver 4 is a one-time purchase rather than a subscription.

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.
