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

Annotate your numbers with words, so that they make sense to you. Soulver picks out the numbers and calculates your answer as you type. Do calculations over multiple lines, and refer to previous lines, much like a spreadsheet.

Soulver is great for adding things up, doing all kinds of percentages easily, and converting things, like currencies. It's quicker to use than a spreadsheet, and smarter and clearer than a traditional calculator.

Key Features:

- A text editor for working stuff out & doing quick calculations.
- Use words amid your calculations so your numbers make sense
- Easily do percentages ("$120 - 10%", "30 as a % of 200")
- See a running total of all your lines
- Do easy conversions ("10 USD in Euros, "22 feet in meters")
- Do calculations with stocks ("100 AAPL")
- Refer to previous lines using tokens.
- Create variables to hold frequently used numbers

- Save your work & share it with the iPhone & iPad versions of Soulver.

Very nearly perfect. I’d love to see a ‘draw a line under this’ feature so I could kind of checkpoint the running total figure at a certain stage and then start fresh on the next line. I tend to use this as an always-open scratchpad which I can refer back to during the day; unfortunately having a single running total number doesn’t make sense in that use case since my calculations are not related. I don’t really want multiple windows open since I just want to get in it quickly.

Fantastic app!


I’ve used Soulver for years and it’s a fantastic tool the entire time. I use it every single day for school or family finances. Other classmates have been blown away by how easy it is to use and how much easier it is to make calculations and formulas than Excel. Thanks, Soulver!

Extremely well designed program


I wish more programs followed the design principles of Soulver. It does one particular thing very well, which is to act as a bridge between the features of a calculator and a spreadsheet. This solves a surprising number of the numerical exercises that I go through every day, both in the realm of finance (job) and electronics (hobby). By allowing you to save your sessions, you can encapsulate knowledge in a way that's more transparent than a spreadsheet, where the formulas must be examined cell by cell and can't be scanned holistically, as Soulver allows you to do. Can you replicate Soulver with Excel? Of course. But do you need to wait for Excel to load, utilize the memory it uses, etc.? Not for a great many problems. Soulver sits open on my desktop most of the time, and I tend to use it for scratch calculations, thought exercises, and rapid prototyping of numerical algorithms. Very useful, not expensive, and well designed.
