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.
