Practical Tools

什麼是 Practical Tools？

You Google "profit margin calculator", You get three ads, a cookie banner, and a form asking for your work email. That's why I built Practical Tools - 134 free tools, no signup, no ads. The food cost calculator my café-owner friend uses to check every new menu item. The spin the wheel we use in standups. The random team generator teachers love. Invoice builder, NDA generator, QR codes, tip splitter. Open a tool, get your answer, close the tab. Still building, would love to know what's missing.
