# Petter Days

> Petter Days is a pet care journal for iPhone and iPad, published by ZhenHui Wang. Official website: https://petterdays.app/.

## Product facts

- Record each pet's water, meals, weight, medication and grooming; create custom record fields, care plans and supply inventory.
- Requires iOS 18 / iPadOS 18 or later. Available in Simplified Chinese, Traditional Chinese, English, Japanese and Korean.
- Core records work offline and are stored on the device. No Petter Days account is required.
- Optional iCloud sync and household sharing require Petter Days Pro. Each participating caregiver needs a separate Pro subscription. Sharing covers the whole household.
- NFC shortcuts require a compatible iPhone and a separately obtained writable NFC tag. A tag opens the App; it does not measure a pet's health.
- The App supports care records and observation, not veterinary diagnosis. It does not provide a user-facing AI assistant.
- Prices and subscription availability are shown by Apple for the visitor's storefront; no fixed price or rating is asserted here.
- George (cat / 乔治) and Biscuit (dog / 饼干) are the brand's illustrated characters. The developer-story pages are character storytelling, not factual developer biographies.
