TailTransit — Pet Passport

Organize pet profiles, records, documents, trips and checklists — privately.

TailTransit is a private, offline-first organizer for everything you collect while preparing to travel with a pet.

Build a pet passport: identity, breed, microchip number and registry, weight and measurements, a photo, and trusted contacts.

Keep a health timeline of vaccinations, treatments, health certificates, check-ups, and medication, each with its own expiry date.

Store your own files in a private on-device document vault, and share them redacted by default.

Plan trips with multi-leg itineraries, an editable preparation checklist, a travel kit, and vet tasks with due dates. The crate planner gives a comfort-planning estimate from measurements you enter; it is not an airline or IATA approval.

Create a shareable PDF dossier yourself, with the microchip and contacts masked unless you choose otherwise. Records stay on the device unless you export them. The app is available in ten languages, including full right-to-left Arabic.


Travel, breed, vaccination, airline, import, and veterinary requirements change and differ by country and carrier. TailTransit records what you enter; it is not official guidance and does not guarantee that any airline, border, or authority will accept your pet. Verify every requirement with the relevant official authority, your carrier, the destination, and a qualified veterinarian.
