## Best for

People who calculate in plain text all day and want the answer beside each line instead of a spreadsheet.

## Why it deserves attention

Ratio evaluates each line as you type, with more than 160 currencies, crypto, 150+ units, time zones, dates, percentages, and references to earlier lines. It covers salary and mortgage math, equations, subnets, hashes, and UUIDs, and can open as a notch calculator or terminal command on the Mac. Calculations run locally, with an MCP server for Claude, Cursor, and VS Code. A one-time licence covers one computer with updates included. The trade-off is that live exchange rates need a connection, and it is not a spreadsheet for large tabular models.
