Track your exotic pets with KeeperCore — care logs, a species reference library, and an AI assistant that reasons from your own pet's history. Deepest for tarantulas, scorpions, and jumping spiders, with solid coverage for turtles, tortoises, frogs, and mantids. Reptile coverage (snakes, geckos, lizards) is smaller and growing. FREE: • 5 active pets • 10 AI care messages per day • 8 photos per pet • 1 co-keeper to share a pet's care with • Join community rooms and follow the species you keep • 700+ species reference library • Care logging for feeding, molting, weight, health, and more • Import your collection from a CSV or Excel spreadsheet • Pet profiles with public sharing, and memorial pages • Learning courses and quizzes • A printable enclosure tag — scan it and land on that pet's page PRO (In-App Purchase): • Up to 300 active pets • 100 AI care messages per day • Up to 2,000 photos per pet • Up to 20 video uploads per day • Unlimited co-keepers, plus time-boxed sitter access • Create and own community rooms • AI-powered care insights on Trends • Export care reports to PDF Every pet's page is now built around what it actually is — a desert scene for a bearded dragon, a rainforest canopy for a crested gecko, open water for a turtle. Same care log underneath, easier to tell your animals apart at a glance. Ask Keeper (the built-in AI) about any of your animals — it answers from that animal's own logged history, not generic advice, and tells you when it isn't sure. Log a feeding, track a molt, or ask a care question in plain English. Add a co-keeper to any pet you own — a partner, a roommate, or whoever's covering feedings while you're away — and they can log care and photos for that pet from their own account. You stay the owner. Co-keepers have to already be friends with you on KeeperCore first; it's not open sharing by username. Keepers is where other keepers are: a Home feed built from the rooms you join and the species you follow, a Browse page for rooms, species, and keepers, and an Inbox for messages, activity, and requests. Every keeper has a Keeper Card — what they keep and what they've logged, if they choose to make it public. Rooms can set their own look — an accent color, a taxon mark, a backdrop — so a tarantula room doesn't look like a gecko room. Start a room of your own on Pro, with approval-only membership and a moderation log. Have an idea for KeeperCore? Post it from a chat with Keeper or from the Ideas board, and other keepers can vote it up. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
