Fur Baby — Pet Age Tracker is an iOS application designed to calculate a pet's age in human years using veterinary guidelines rather than the traditional one to seven year ratio. The app supports nine species: dog, cat, rabbit, guinea pig, hamster, parrot, ferret, reptile, and a custom species option. For dogs, the calculation accounts for four size categories (small, medium, large, giant), and for parrots, three size categories are available. The age conversion is based on standards from the American Veterinary Medical Association, the American Animal Hospital Association, the American Rabbit Breeders Association, the Association of Small Mammal Practitioners and Veterinarians, the Association of Avian Veterinarians, and the American Ferret Association. The app operates fully offline, stores all data locally using Apple SwiftData, and does not require account creation or include analytics or tracking software. The application includes several integrated tools. A memory journal, called Moments, allows users to capture photos, mood tags, location data, and use built-in templates. It offers five view modes: list, calendar, map, statistics, and photo grid. A soft delete feature provides a seven day recovery window for removed entries. The wallpaper maker provides six professional templates for creating HD lock screen wallpapers at native iPhone resolution, with no watermarks and no sign up required. Home and lock screen widgets display current human age equivalent, days together, upcoming milestones, and recent memories, refreshing at midnight. Four widget types are available: small card, medium profile, rectangular summary, and inline status bar. Milestone and care reminders can be set for birthdays, adoption days, vaccinations, and deworming, with six repeat intervals (daily, weekly, monthly, quarterly, half yearly, or yearly) and automatic roll forward upon completion. AI powered features include a moment creator that extracts structured data from natural language input, a wallpaper generator using DALL E 3 with multi provider large language model support, and pet insights that generate period summaries with mood trends. Typical use cases include tracking a pet's age accurately for veterinary visits, recording daily moments and milestones, creating personalized wallpapers for the lock screen, and setting recurring care reminders. The workflow involves adding a pet with species and size details, viewing the calculated human age on the home screen or widgets, capturing memories with optional tags and location, and generating wallpapers from the template library. Reminders sync with the iPhone calendar and repeat according to user defined intervals. The app supports up to two pets in the free tier, with unlimited pets, memory records, milestones, and all templates available through a Pro subscription. Export options include PDF, image set, and JSON formats. The app is ad free and designed for iOS devices.
