Hi, I'm Anil - I built a free calculator site with 300+ math tools

Hey Product Hunt community! 👋

I'm Anil, an indie maker from Finland. I recently built DigitHelm (digithelm.com) - a collection of 300+ free online math, science, and finance calculators.

No sign-up, no paywalls, no downloads. Everything runs directly in your browser. Tools cover everything from basic arithmetic to compound interest, BMI, quadratic equations, statistics, physics, and chemistry.

Built it because most calculator sites are either too cluttered or hide results behind paywalls. I wanted something fast, clean, and genuinely free.

Happy to connect with other indie makers here. What are you all building?
