Solvocalculator is a free Polish-language calculator site with 78 tools for everyday math, finance, health, chemistry, physics, and unit conversion. No sign-up, no ads, no fabricated stats. Every formula is hand-verified against a worked example before launch. Sensitive calculators (BMI, blood alcohol, salary) cite real sources like WHO, peer-reviewed research, and Polish law. Built solo with Astro + Cloudflare, using real Polish search-query research to choose every tool.
