Soulver is a smart notepad with a built-in calculator. It gives instant answers to any calculations it finds in your text. It's a better way to work stuff out than with a traditional calculator, and a more lightweight tool for quick calculations than a spreadsheet.

Soulver is great as a simple calculator replacement. But it really shines when you use it to explore different scenarios and experiment with numbers. You can you use words and numbers alongside each other and you almost never encounter an error. And all your work is automatically saved for you so you can reference it later.
With Soulver you can see and edit all your calculations, all the time. Unit conversions, including live real-world and cryptocurrencies are built-in. Use headings, labels and comments to give your notes structure, and enjoy automatic formatting features and tasteful syntax coloring.
Soulver comes with a set of natural language functions that make it easy to do common operations. For example, working with dates, times, percentages and proportions is easier than ever. And we're always thinking of new ways to make common tasks involving numbers more natural for the human brain.
Soulver comes with a stack of handy features for doing multi-step calculations. For instance, you can reference previous lines, kind of like a spreadsheet. And like a programming language, you can assign names to numbers and use them as variables in your calculations.
A total at the bottom automatically adds up all your line, and you can make subtotals of specific lines.
"I think this is actually my most used Mac app ever, I don't even remember life before Soulver. Everything from UI calculations to planning how much money we might make, this is the tool I reach for."
