Hey Product Hunt! 👋 I'm Santosh, the maker behind TrueTools. I kept running into the same frustration: every time I needed a quick calculation — profit margin, employee cost, currency conversion — I'd land on a site loaded with pop-ups, asking me to sign up, or quietly harvesting my data. So, I built TrueTools. 200+ tools across 12 categories, all running client-side in your browser. No data ever leaves your device. No accounts. No tricks. A few things I'm proud of: — Every formula is verified against official sources (tax codes, medical standards, financial formulas) — Localized tools for US, UK, Canada, and Australia — Fully accessible (WCAG 2.1 AA, keyboard-friendly, screen-reader compatible) — Dark mode because we're not animals 🌙 I'd love to hear which tools you find most useful — and what's missing. I'm actively building new ones, and your suggestions go straight to the top of the list. Thanks for checking it out! 🙏
