Scientific expressions
Variables, complex numbers, vectors, matrices and reproducible results.
A beautiful, always-at-hand workspace for everything from a quick expression to complex matrices, uncertainty, plotting and numerical tensor analysis.
Mac TestFlight beta · Version 0.7.0 (8) · Public release in preparation

The worksheet keeps the logic in view while the engine handles numerical operations and the structures behind them.
Variables, complex numbers, vectors, matrices and reproducible results.
Simplify, expand, differentiate and evaluate a supported class of algebraic expressions.
Metric-aware numerical tensor operations with upper, lower and barred index attributes.
Dimensional consistency and covariance-aware propagation for real measurements.
Two-dimensional plots built directly from the arrays in your worksheet.
Floating Mac interface with saved position, keyboard history, New, Open and Save.

Write a definition, evaluate it, inspect a result, and carry it forward. The worksheet builds an understandable line of reasoning without becoming a programming project.
