As answered by people managing DeveloperTools.Tech and BreedTools.app.
BreedTools.app's answer:
BreedTools is the only free breeding management PWA that covers the full breeding lifecycle — from heat cycle and progesterone tracking to live whelping logs, Volhard temperament testing with automatic buyer-puppy matching, digital contracts, and a complete stud owner module with frozen semen inventory. It works offline, requires no app download, and runs on any device instantly.
BreedTools.app's answer:
BreedTools is free where competitors charge, more feature-complete than anything at its price point, and works offline without an app install. It includes features competitors don't offer at any price — Volhard temperament testing with buyer matching, frozen semen inventory tracking, semen analysis records, verified stud service reviews, and a full 7-stage buyer CRM. Pro is $9/month versus $10-12/month for less capable alternatives.
BreedTools.app's answer:
Serious hobby and professional dog breeders — AKC registered breeders, kennel owners, and stud dog owners who manage multiple dogs, litters, and buyers and need more than a spreadsheet. Also serves breeders entering their first litter who want a professional setup from day one.
BreedTools.app's answer:
BreedTools was built by a solo founder who saw that existing breeder software was either too expensive, too basic, or too clunky for how real breeders work. Starting with a free tools site at breedtools.com, the platform expanded into a full PWA so breeders could manage their entire program — from first heat cycle to puppy go-home day — in one place, free, on any device.
BreedTools.app's answer:
