I built a free, offline pet vaccine tracker (no account, multiple pets, vet-ready PDF)

Vaccine schedules are one of those things that are easy to start and easy to lose track of — especially with puppies and kittens, where the timing actually matters, and even more so with multiple pets on different schedules.

I built a small, free tool for exactly this, and I kept it deliberately boring and private.

A pet vaccine tracker that stays on your device

  • No account, no sign-up, works offline. It's a PWA — your pet's records live in your browser, not on someone's server.
  • Vaccination + deworming reminders so you see what's due at a glance.
  • Multiple pet profiles — dogs and cats, each on their own schedule.
  • Weight tracking + a photo log, and a vet-ready PDF you can hand over at an appointment.
  • 8 languages.

Why on-device

Most "pet health" apps want an account and sync your data to a cloud you don't control. For something as simple as "did the puppy get its 12-week shots?" that felt like overkill. Local storage is enough, and it means nothing leaves the device.

It's free

The core tracker is free and stays free. If a guide helps you, there are optional "where to buy" links for the consumables (flea/tick, dewormers) — that's it.

I'm building this in the open. If your vaccine workflow needs something it doesn't do yet, tell me.
