How it works

Your child wears their Apple Watch.

Step counts are recorded automatically via HealthKit — no manual logging needed.
Their pet reacts to movement.

Walk to school, the rabbit perks up. Sit all day, it naps. Every step counts toward a happier pet.
The pet grows over time.

Hatch from an egg, grow to a baby, then young, then adult rabbit. Consistent activity unlocks each stage.

The pet lives right on the watch face. One glance tells your child how their activity is going today.

We know you have questions.

Health data privacy: Health data never leaves your child's watch. There is no server, no account, no cloud sync. HealthKit data is read-only and stays on device.
No addiction mechanics: There is no decay, no punishment, and the pet never dies. The worst state is a peaceful sleeping animation. Maximum two notifications per day.
Price: Watchie Besti is a one-time purchase. No subscription, no in-app purchases. Family Sharing enabled — one purchase covers all children on the family plan.
Age appropriateness: 4+ age rating on the App Store. No violence, no social features, no chat. Designed for kids aged 10–14 in the Apple Kids Category.
Battery drain: Watchie Besti uses Apple's lowest-power HealthKit observer mechanism. It does not run a background process or poll for data on a timer.
