Soulver

Absolutely brilliant app. It feels almost psychic in its approach to helping solve mathematical problems. Soulver bridges a four-way gap between the calculator, notepad, spreadsheet, and code in a way that feels more elegant than I ever could have imagined.

Incredible stamina and pace of development. Soulver improves constantly.

Great idea that turns the traditional calculator on its head, but in a good way. Perfect for some small calculations with a few variables!

Soulver is a smart notepad with a built-in calculator. It gives instant answers to any math 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.

If you're not using Soulver 3 as your goto calculator then you could be using the next best calculator which is... umm... umm... umm... Nevermind, Soulver is simply the best!
