Hey Product Hunt 👋 I'm Moksh, the maker of Stepwise. It started with a small annoyance: every time I needed to work something out (a loan payment, BMI, a unit conversion, how much paint for a room), I ended up on a different site covered in ads, and the result was just a number with no explanation. I couldn't tell if it was right. So I built one place for all of it, with a simple rule: show the working. Every calculator on Stepwise walks through the formula step by step, so you can check the answer, learn the method, or show it to someone else. What's inside: • 480+ calculators and tools across finance, health, math, construction, science and conversions • Instant search, so you can type "mortgage" or "kg to lb" and go • Clean dark/light design that works well on phone and desktop • Free, with no sign-up • Everything runs in your browser, so your numbers stay on your device, and it works offline As it grew, the hardest part was keeping the results trustworthy at this scale. Formulas are checked against official sources, and tax figures are kept up to date for 2026. I'd love your feedback: → Which calculator do you use most often? → What's missing that you'd want added next? Thanks for checking it out! 🙏
