Enter calculations into any Service-aware app such as TextEdit, Mail, Messages, Safari, or Xcode, and calculate the result with a single keystroke. Append the result to the formula, replace the selected text with the result, or show the result in a panel. Never launch Calculator again if you just need a quick calculation.

Release notes:
This release brings full support for M1-based Macs. In addition, the parser now supports "x" instead of "*" in multiplications.
