Soulver for Mac is a powerful hybrid between a calculator app and a text editor, allowing you to make quick calculations using a notepad-like interface. Now, version 3 of Soulver has been released with new features like a redesigned interface, date and time math, Dark Mode, and more.

Here’s how the developers behind Soulver describe the app:

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 3 features a new interface that’s far more lightweight than the previous iterations, and supports Dark Mode. There’s also support for date and time calculations, allowing you to make calculations based on days, weeks, and months. Other new features include a built-in sheets manager, subtotals, new functions, units, and currencies, and more. In total, Soulver 3 includes 50 new features. The full changelog is below.

At this point, if you run Soulver on your iPhone and Mac, they do not sync because of the different file formats and math engines used by each version. Soulver 3 is not available as an upgrade to Soulver 2, nor is it available from the Mac App Store. It’s available from the Soulver website for $19.95 with a free 30-day trial.
