Whisker: Pet Health

Whisker is a private, local-first health record for the pets you love. No accounts, no cloud, no ads — every entry stays encrypted on your iPhone, and you decide if and when to share it.

WHAT YOU CAN TRACK
• Pet profiles — species, breed, birth date, microchip, allergies, chronic conditions
• Vaccines & deworming with next-due reminders
• Medications and dosing schedules
• Weight, feeding and excretion logs
• Vet visits, grooming, nail trims and custom events
• Lab values (ALT, BUN, CREA, T4 and more) extracted automatically from scanned reports

WHY LOCAL-FIRST
Your pet's medical history is sensitive. Whisker stores everything inside the iOS sandbox using a 256-bit encrypted database. There is no Whisker server. We cannot read your data — because we never receive it.

ON-DEVICE INTELLIGENCE
• Apple Vision OCR turns paper lab reports and prescriptions into structured data, on your phone
• Apple Health integration pulls your daily steps so you can correlate exercise with your dog's weight curve
• Apple Foundation Models (iOS 26+) extract lab values from messy or handwritten reports — fully on-device

PREMIUM
Whisker Premium unlocks:
• Unlimited pets
• Insurance-grade PDF reports for vet visits and claims
• Apple Health integration
• 6 themes (warm cream, midnight, forest, ocean, rose, mono)
• 12-word encrypted backup (BIP39 seed phrase) for restore-on-new-phone

Premium options:
• Monthly subscription
• Annual subscription (best value, with optional free trial)
• Lifetime — one-time purchase, never expires

PRIVACY
• No account required, ever
• No analytics, no telemetry, no third-party SDKs that phone home
• Camera + Vision OCR runs entirely on your device
• Apple Health integration is read-only and on-device
• Backups are encrypted with a key only you hold (your 12-word phrase)
• Family sharing (when enabled) uses Apple's MultipeerConnectivity — peer-to-peer over local Wi-Fi, never through our servers

WHO IT'S FOR
• Multi-pet households who can't keep paper records straight
• People who change vets and need a portable medical history
• Anyone who values privacy enough to host their own data

Whisker stays useful even with no internet — at the vet's office, in the car, on a hike. Your records belong to you.
