As answered by people managing PetPawCalc and CloudShell.
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.
