Pet Book: Your Pet's Vaccines, Weight and Vet Notes — Private, on Your Phone
The paper vaccine card is in a drawer somewhere, the next rabies shot is “sometime next spring”, and at the vet you cannot remember when the vomiting started. Pet Book keeps one simple health book per pet on your own phone — with reminders you control and a page you can hand to the vet.

The problem
Pets are family in a huge number of homes: the American Pet Products Association's 2025 National Pet Owners Survey counts 95 million US households with a pet, and Americans spent $158 billion on their pets in 2024, $41.0 billion of it on vet care and products. Yet the record of all that care is usually a paper booklet that gets lost when you move, plus a few dates in your head. Boosters, deworming and flea treatments slip past. At the appointment the vet asks “how long has she been off her food?” and nobody is sure. Most pet apps that could help are tied to a clinic chain or a shop and want an account, your address and your phone number before they do anything.
How Pet Book (Pet Health Log) works
- Type your pet's name and pick dog, cat, rabbit, bird or other — that's the whole setup. Add a photo, breed, birthday and the microchip number from the vet's paperwork when you have them.
- Copy each vaccine, deworming, flea-and-tick treatment or medicine from your vet's card: the date it was last given and how often it repeats. Pet Book works out the next due date and shows what is coming up first on the home screen. It never suggests a vaccine or an interval — that stays with your vet.
- When something seems off, tap a chip such as “Vomiting” or “Not eating” and Save — two taps. Add a note or a photo if you want. Weigh-ins go into a chart in kg or lb, even if you mix both.
- Before a visit, print the one-page vet report. If your pet ever goes missing, the lost-pet card with photo and phone number is ready to save as an image or print as a poster.
What you get
- Next due dates, worked out for youEnter the last date and the repeat (for example every 12 months, or every 3 months for deworming) and Pet Book shows the next date, colour-coded: overdue in red, within a week in amber. Tap Done after the appointment and the following date is set from today.
- Calendar reminders 7 days and 1 day beforeWith Pro, one tap exports a standard .ics file for all your pets. Import it into Google Calendar, Apple Calendar or Outlook and each due date arrives with two alerts — a week ahead to book, a day ahead to remember.
- A two-tap symptom journalChips for the things vets ask about — not eating, vomiting, diarrhea, itching, lethargic, coughing, limping, drinking a lot — plus notes and photos. The journal answers “since when?” with dates instead of guesses.
- A one-page report for the vetProfile, microchip number, latest weight and a 12-month weight chart, medicines, the vaccine and treatment table, the last 90 days of the journal and your questions — fitted to one A4 or US Letter page. Print it or save it as a PDF.
- An “if I'm lost” cardYour pet's photo, name, your phone number, a short message, medical needs and the microchip number on one card. Save it as a 1080×1920 image for your lock screen or share it in seconds, or print a poster. Free for every pet.
Private by design
Pet Book has no account and no server. Profiles, schedules, weights, journal entries, costs and photos live in your browser's storage on your phone and are never uploaded. Photos are redrawn and compressed on the device, which strips location and camera data and keeps each one under about 300 KB. Your phone number appears only on the lost-pet card you choose to share. The only network request is the one-time check of a Pro licence key. Pet Book is a record, not veterinary advice: it does not diagnose, it does not recommend vaccines or doses, and it is not linked to any microchip registry, clinic or lost-pet service. For urgent signs — trouble breathing, collapse, suspected poisoning, long or repeated seizures, a cat straining to pee — it points you to call a vet now, citing the AVMA and the American College of Veterinary Surgeons.
Free vs Pro
FAQ
Does Pet Book tell me which vaccines my pet needs?
No, on purpose. Vaccine requirements differ by country, species, lifestyle and even local law, so the schedule must come from your vet. Pet Book only suggests common names to save typing and reminds you of the dates and intervals you enter.
Is it free?
Yes. One pet with the care schedule, next due dates, weight chart, symptom journal and lost-pet card is free forever. Pro is $1 once — not a subscription — and adds more pets, calendar reminders (.ics), the one-page vet report, costs by month and category, and backups that include photos.
Can I use it for more than one pet?
The free version keeps one pet. With Pro you can add as many as you have and switch between them with one tap; the calendar file covers all of them.
Where is my data stored, and what if I change phones?
Only on your device, in the browser. Nobody else — including us — can see it. Use Settings → Back up to a file and keep that file somewhere safe; on the new phone, open Pet Book and restore it. Install the app to your home screen so the browser does not clear it.
Does it find my pet if it gets lost?
No. Pet Book does not track location and is not connected to any microchip database or lost-pet network. It makes a clear lost-pet card and poster quickly so you can share it with neighbours, shelters and local groups — and it reminds you to keep the microchip registration up to date with your registry.
