Cavy Management Add unlimited cavy profiles with everything you need: name, gender, breed, coat color and type, date of birth, photo, and a unique QR cage ID. Record parents, litter association, registration and pedigree numbers, microchip ID, acquisition details, weight, and custom tags. Mark cavies as deceased, sold, or neutered. Search your herd by name, breed, color, gender, parent name, or litter number, instantly. Litter Management Track every litter from planning to weaning. Record parents, breeding date, expected and actual birth dates, offspring counts, survival rates, average birth weight, and lifecycle stage. A built-in D-Day countdown shows how many days until the next expected birth, color-coded so overdue litters stand out. Toggle between list view and a full month-grid calendar showing breed dates, expected births, and actual births as color-coded dots. Inbreeding Coefficient (COI) Whenever you select both parents on a litter, Pigree instantly calculates Wright's coefficient of inbreeding in real time. A collapsible banner shows the severity level: distant, moderate, high, or critical. Lists all shared ancestors, and explains the formula. The family tree also displays a COI badge directly on the subject card.

Breeding suggestions surface up to 5 compatible male/female pairs with low COI, new pairs shown first. QR Codes Generate a unique QR code for every cavy and share it as a PNG. Use the built-in scanner to instantly navigate to any cavy profile, perfect for busy breeders managing large herds. Birth Reminders Never miss a birth.

Verdict
The clearest difference is price: Pigree at Free against WhosDue's $9.99. Pigree also leads on update cadence (every 10 days vs every 3 months). WhosDue's advantage is in-app purchases (none vs 4) and chart position (#190 vs unranked). On ads, device support and iOS requirement there is nothing between them.
