It's quicker to use than a spreadsheet, and smarter and clearer than a traditional calculator.
Use Soulver to play around with numbers, do "back of the envelope" quick calculations, and solve day-to-day problems.
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 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.
