RatioVerified on MacBase

Ratio is a notepad calculator for Mac, Windows, and Linux. Type calculations in plain language—such as “5 km in mi,” “3pm in Tokyo,” or a shared dinner—and it shows each answer beside the line. It handles currencies, crypto, units, dates, time zones, formulas, statistics, lists, plots, loan schedules, and more. On the Mac, Ratio works offline, offers live currency rates when connected, and can appear from the menu bar or notch. Apple Intelligence answers questions locally on your Mac. Results keep their working, support line references, and can be reused or updated throughout a note. A Terminal command is also included.
