Built solo with Astro + Cloudflare, using real Polish search-query research to choose every tool.

Hey Product Hunt! I built Solvocalculator because most Polish calculator sites feel like 2005-era ad farms, or give you a number with no way to check how it got there. Every calculator here is verified against a hand-computed example before it ships, and anything genuinely sensitive — health, alcohol, salary — links to a real source instead of just showing a value. Still early days: 78 calculators live, all built from real Polish search demand rather than guessing what might be useful. Would genuinely love feedback, especially from anyone in Poland who can tell me what's missing.
