## Full description

Ratio is a notepad that calculates as you type. Write a line like "rent 1,200 + bills 180" or "3pm in Tokyo" and the answer appears beside it. It handles 160+ currencies with live rates, crypto, 150+ units, dates and time zones. Change one number and every line below updates. Split bills by name, work out salary or loans, and solve equations. Everything runs on your computer, works offline, and you buy it once for Mac, Windows or Linux.
