Hey PH! 👋 I built Calcosy after getting frustrated with calculator sites that hide results behind signup walls and email popups. Just let me calculate. A few things I'm proud of: The home page has a working basic calculator right next to the search bar — no clicking needed Every calculator has a plain-English explanation of the math, not just the formula The pet calculators (chocolate toxicity for dogs, cat age, dog lifespan) were unexpectedly popular during testing Home improvement is the most searched category — roofing, deck, solar panels, concrete Happy to answer any questions about the tech stack (React + Vite + Supabase) or how I built 175 calculators without losing my mind. What calculator should I add next? 🧮
