Soulver is a beautiful notepad calculator app that you will love. It has a new interface that is far more useful than a traditional style calculator, which lets you do calculations over multiple lines, and use words alongside numbers, so that they make sense. Use it for quick calculations, calculations involving variables & percentages, unit conversions, and for thinking through problems that involve math.


– Instant answers as you type.
– Spread your calculations over multiple lines, and edit mistakes if you make them.
– Reference previous answers by tapping on them. These are live references, like in a spreadsheet.
– Easy percentage calculations using natural phrases like "15% off $350”, or "$250 + 12% tax", or "40 as a % of 390".
– Supports over 150 currencies (including Bitcoin), and has a specially designed currency keyboard for quick conversions.
– Custom variables across all your documents, and a special keyboard for quick access to them.
– All standard math and programming functions, also available on specially designed keyboards.
– Save your calculations into documents.

Soulver is also available for macOS.

Dark mode?

Great app! I have it on my Mac as well! Only feature I wish it had was dark mode! Any future plans for dark mode on Mac and iOS?

I know you got Soulver

Best calculator app imaginable: more like an interactive ledger that anticipates your every move once you learn even a fraction of its powerful, intuitive feature set. Supports all kinds of variables, line references, currency conversion, formatting, you name it. Yet it does not feel at all cluttered, it stays out of your way and lets you stay solving!
