As answered by people managing GitHub Codespaces and PetPawCalc.
PetPawCalc's answer:
Built as a solo indie project to fill a gap: most calculator sites are generic. PetPawCalc focuses entirely on the questions real pet owners search for every day.
PetPawCalc's answer:
All calculators are built exclusively for pet owners — not generic math tools repurposed for pets. Every tool is designed around real questions pet owners ask, like how old is my dog in human years, how much should I feed my cat, or what will my dog's adult weight be.
PetPawCalc's answer:
PetPawCalc is 100% free with no signup required and no paywalled features. It focuses entirely on pet-specific calculations, so users get accurate, relevant results without digging through unrelated tools.
PetPawCalc's answer:
Dog and cat owners in the United States who want quick, reliable answers to everyday pet care questions — from feeding and weight to costs and health schedules.
PetPawCalc's answer:
HTML, CSS, JavaScript — fully static site built with Jekyll and hosted on GitHub Pages.
