Every pet app I tried wanted the same three things before it would let me write down a single vaccine date: an account, an email, and permission to keep my dog's records on someone else's server.
I just wanted to remember when the next rabies shot was due.
So I built PetHealthLog - a pet health record that works the opposite way.
What it does
- Vaccination & deworming reminders - log a shot, see the next due date at a glance.
- Weight chart - plot weight over time and spot trends early.
- Photo album - keep before/after photos with each entry.
- Vet-ready PDF - export a clean one-page summary to hand (or email) to your vet.
- Multi-pet - one place for the dog, the cat, and the senior rescue.
The part that matters
It runs fully offline, needs no account, and your data never leaves your device. There's no sign-up wall, no sync server quietly holding your pet's history, no inbox full of "we updated our privacy policy" emails.
Open the link, add a pet, start logging. It's a PWA, so you can install it to your home screen and use it on a plane, at the kennel, anywhere - no signal required.
It's free and available in 8 languages.
Why offline-first?
A pet's health record is small, personal, and yours. It doesn't need the cloud. Keeping it local means it's private by default - not by policy. Nothing to breach, nothing to sell, nothing to lose access to if a startup shuts down.

If you keep a paper folder of vet receipts and vaccine cards in a drawer somewhere, this is that drawer - searchable, exportable, and in your pocket. I'd love to hear what's missing for your pets.
