Our verdict on Expresso

Expresso is a macOS text editor for people who want calculations inside rich-text documents. It combines rich-text editing with inline mathematical expressions, variable assignment, reusable results, and automatic recalculation of dependent expressions. Expressions can appear throughout a document, while annotations and tables help organize the surrounding calculations. The focus suits users working through taxes, costs, profits, or other figures alongside explanatory text rather than users seeking a broad general-purpose writing tool.

Its freemium structure keeps the basic workflow accessible. The Free plan includes a Mac app, rich-text editing, and inline calculations. The $0.99 Expresso Pro Pack adds advanced calculation features, including calculating expressions without brackets on separate lines and hiding or showing expressions and values. That makes the paid tier relevant when calculation presentation and more flexible expression handling matter, while the free tier covers the core combination of text and inline calculations.

Expresso’s standout feature is the way calculations live within the document instead of being separated from the surrounding text. Variable reuse, dependent-expression recalculation, annotations, tables, RTF saving, and clipboard copying support a calculation-heavy document workflow. Its scope is also narrow: the published feature set centers on mathematical expressions and calculation organization, and the app supports macOS only. The latest listed version is 1.4, dated March 4, 2014. Choose Expresso for lightweight Mac documents that combine prose and changing calculations; choose another text editor if general writing breadth or a different platform matters more.
