Most calculator sites are an eyesore — ads everywhere, terrible mobile UX, and results with no explanation of what the number actually means. Figured I'd take a shot at doing it properly.
30 calculators across fitness, finance, math, and baby/parenting. The fitness ones are linked — BMR flows into TDEE, which flows into calorie deficit, which flows into macros — so you don't have to re-enter your data at each step. No ads, no signup. Built with Next.js 16, React 19, Tailwind v4.
Two questions for the community: how do you monetize a free tool site without going the ads route? And — what calculator do you use regularly but can never find a decent version of? All feedback, criticism, and suggestions welcome.
