App Description

Note: This is NOT the universal version of Soulver.

There is a universal version of Soulver available and future features will only be available in that version. If you would like to purchase Soulver, get that version instead.


Soulver is the essential app for doing quick calculations and figuring stuff out on the iPad.

Write out calculations line by line on the notepad on the left, and the answers are displayed instantly on the right. All your work is visible all the time, and you can go back and change any line. It's like doing math on paper, except the calculator is part of the page.

Soulver is unique in that it allows you to use words alongside your numbers, so your calculations actually make sense. It's great for shopping (discounts, totals), or just about any day-to-day calculations. It's so easy to play around with different scenarios, figure out profit margins, and compare different options lines by line.

Soulver displays a total of all your lines, and your work is automatically saved, which is perfect for keeping track of daily expenses, budgeting and travelling. You can easily work out percentages too, as Soulver supports over 14 different percentage operations which is great for quick markups (tax tips, etc). You can also do currency conversions.

Once you try Soulver, you'll never want to use a traditional calculator again.
