TinyTail is the calm, all-in-one app for everything your pet needs, powered by Tiny, a friendly AI companion who knows your pet and is always ready to help. Whether you are a first-time pet parent or you have had companions for years, TinyTail keeps your pet's daily care on track and answers the questions that come up along the way. MEET TINYTAIL, YOUR AI PET CARE COMPANION Ask TinyTail anything: is this a healthy weight, how much should I feed, is this food safe, what is a normal routine for this breed. Tiny knows your pet's age, species, and history, so answers fit your pet, not a generic search result. CARE THAT NEVER SLIPS Track feeding, medications, and checkups in one place. TinyTail keeps each day on track and reminds you before something is due, so heartworm tablets and vet visits never fall through the cracks. HEALTH AT A GLANCE Get a clear summary of how your pet is doing, with overall condition, weight trends, and gentle watch-this notes, so you always know what is going well and what deserves attention. BUILT FOR EVERY PET IN YOUR HOME Give each pet their own profile, photos, and history, and switch between them in a tap. BROWSE FREELY Explore the app and see how it works before you ever sign in. Sign in with Apple when you are ready to save your pets and sync across your devices. A note on health: TinyTail offers general guidance to help you care for your pet. It is not a substitute for professional veterinary advice. For emergencies or medical concerns, always contact your veterinarian.
