Gauss - Notepad calculator for Mac with units, currencies &dev tools

Gauss is a notepad-style calculator for macOS. Type math the way you think — with words, units, and currencies — and get instant results on every line. No buttons, no equals sign, no separate conversion apps. 80+ unit conversions, 170+ live currencies, and developer tools like color conversion, base64, and timestamps. 4x cheaper than Numi ($4.99 vs ~$20). 7-day free trial, one-time license.

Hey Product Hunt! I built Gauss because I was tired of switching between Spotlight, a calculator app, a unit converter, and Google for currency rates — just to do quick daily math. Gauss lets you type naturally on every line: "150 USD to EUR", "5kg to lbs", "sin(45)", even "#FF5733 to rgb". Results appear instantly, no buttons needed. What makes it different from Numi/Soulver: - 4x cheaper ($4.99 one-time vs $20+) - Developer tools built in (color conversion, base64, timestamps) - 170+ live currencies, not just major ones - Modern Liquid Glass design for latest macOS 7-day free trial, no credit card required. Would love your feedback!
