Show HN: SlickCalc – 30 free calculators, no ads, dark UI

https://slickcalc.com

I got tired of using calculator.net (looks like 2003) and OmniCalculator (ads everywhere), so I built my own: https://slickcalc.com

30+ calculators covering finance, health, math, and more. Dark theme, real-time results, mobile-friendly.

Tech stack: Next.js 16, TypeScript, Tailwind v4. All computation is client-side — no backend, no tracking. SSR for SEO, ~350KB total page weight, CLS 0.

Blog posts embed working calculators via MDX, which was fun to build.

No revenue yet, just a side project. Curious what tools you'd find useful.
