Live maths
Define variables with :=, reuse them anywhere on the sheet, and see
results rendered inline as you type.
Maths Explore is a web app for engineering calculations. You place blocks of maths, text, and diagrams anywhere on paginated sheets (A4 or US Letter). Maths is evaluated in reading order against one shared scope, so results update everywhere the moment you change an input — like a spreadsheet, but written as real mathematical notation.

Units built in
Attach units like 2.mm or N.m to any value. Results carry their
units, and you can convert them per block.
