One app for every animal you keep. If you keep more than one kind of exotic, you've been juggling apps that each cover half your collection. XenoKeeper is the one field journal for all of it — reptiles, tarantulas, fish, amphibians, scorpions, isopods, and everything in between. 2,536 species across 10 categories, in one place. Open it at the rack, log a feeding, close it. Open it over coffee, plan the week, close it. No account, no sign-up screen, no setup wizard — add your first animal and go. Works fully offline, wherever your animals are. — WHAT IT TRACKS — - Feeding, phase-aware. Multi-food entries with size segments and rejection tracking ("3 small dubias, 1 large cricket — she refused the hornworm"). The overdue clock understands biology: your tarantula hits pre-molt and feeding pauses; your corn snake finishes a shed and the schedule resumes from the right date. - 23 event types. Molts, sheds, brumation, gravidity, metamorphosis, glass-surfing, cohabitation, habitat shifts — each with start/end phases that feed straight back into your feeding logic. - Measurements & growth. Weight, length, temperature, humidity — metric or imperial with a tap. Growth curves draw themselves as you log, from an 8-gram hatchling to a full-grown adult. - Habitats. Set target temperature and humidity ranges per enclosure — terrestrial, arboreal, fossorial, semi-aquatic — and tie each animal to its home. - QR codes. Generate per-animal or per-habitat codes, batch-print a sheet, stick them on every tub, and scan to jump straight to that record. The fastest path from "spotted something" to "logged it" when you've got 40 enclosures. - Colonies. Dubia roaches, isopod cultures, ant farms — colony size tracked as a real measurement over time, not shoehorned into individual-animal fields. - Safety flags. Venom and urticating-hair warnings on the species record, visible at a glance. — BUILT FOR HOW YOU KEEP — Reptiles & amphibians: shed-aware feeding, brumation as a first-class state, life-stage transitions from hatchling to adult. Ball pythons, leopard geckos, bearded dragons, corn snakes, crested geckos, dart frogs, axolotls. Arachnids & inverts: molt phases that drive feeding logic, venom and urticating-hair flags, colony support. Tarantulas, true spiders, emperor scorpions, mantids, beetles. Aquatics & semi-aquatics: aquatic/terrestrial transitions as a built-in event; temperature, humidity, and lighting tracked together. — YOURS TO KEEP — - No account required to start. Want cloud sync and backup? Create a free account anytime — they're included, not a paid add-on. - Works offline — at the expo, the field shed, anywhere. - Open import and export. Bring your collection in, back it up to a .zip, take it with you. Your data is never held hostage. — ON THE WAY — A community hub to connect with other dedicated keepers, plus breeder tools — pairings, clutch management, and offspring lineage — are actively in development. XenoKeeper is free to start. Optional Pro and Pro+ subscriptions add higher animal limits, themes, and community features. Pro and Pro+ are auto-renewable subscriptions, offered monthly or annually. Payment is charged to your Apple Account at confirmation of purchase. Your subscription renews automatically unless auto-renew is turned off at least 24 hours before the end of the current period. Your account is charged for renewal within 24 hours before the period ends. Manage or cancel anytime in your Apple Account settings.

Verdict
The clearest difference is ads: MoltMate at none against XenoKeeper's shown. XenoKeeper's advantage is update cadence (every 8 days vs every 3 months). On price, in-app purchases, device support and iOS requirement there is nothing between them.
