Hatch and raise a digital pet on your Apple Watch that responds to your daily steps and movement.
Your Apple Watch just grew a heartbeat. WatchieBesti's pet hatches from a mysterious egg, grows through real life stages, and feels every step you take — or skip. Move and watch it thrive. Sit still and watch it get sleepy. Just wear your watch — no setup, no extra taps.
Free to download. No ads. No subscriptions. Three kingdoms — Animals, Plants, Machines — buy one or all. Family Sharing covers every Apple Watch in your family.
THREE KINGDOMS,
MANY SPECIES
Every egg is a secret. Hatch into Animals, Plants, or Machines — three kingdoms, dozens of species to discover. Your first pet might be a rabbit that twitches its ears when idle. Another egg could reveal something leafy, tiny, shiny, mechanical, or entirely unexpected.
Every species grows with its own stage names and unique look at each stage. Collect multiple colour variants, give your pet a name, then graduate it into your family collection and start again.
YOUR PET FEELS YOUR DAY
Eight moods shift in real time based on how active you are:
Happy when you are moving. Sad when you have been still too long. Ecstatic when you blow past your typical activity. A warm morning glow greets you when you wake — brighter if yesterday was a great day. Push hard during a run or climb stairs fast, and your pet gets a temporary burst of energy.
At bedtime, it sleeps. During focus time, it waits quietly without sending notifications.
Your pet is not a judge. It is a mirror — reflecting your day back to you with warmth.
WORKOUT STICKERS
Run, walk briskly, kayak, hike, swim or climb stairs — every detected workout becomes a collectible sticker on your mood ring. Medal tiers from bronze to legendary track each workout type.
BRAIN BOOST MINI-GAMES
Five mini-games live right on your watch. Challenges appear throughout the day — short, sharp rounds built for quick play. Win to unlock a Brain Burst: a special mode where your pet becomes a glowing star student and earns a bonus to its activity score.
SEE YOUR DAY AT A GLANCE
A 24-hour mood ring circles your pet, showing how its mood shifted through every hour. Workouts arc onto the ring as coloured segments. Tap to open a timeline.
WAKE UP WITH YOUR PET
A morning summary greets you with yesterday's highlights — your pet's final mood and how the day ahead could shape up.
GRADUATE, COLLECT, ACHIEVE
When a pet reaches adulthood, graduate it to your family collection and start fresh with a new egg. Over time, build a family across all three kingdoms. Visit them in their lush habitats.
Earn achievements along the way: milestones for your first egg, first hatch, first ecstatic day. Streak tiers from bronze to legendary. Collection badges for full colour sets or completed kingdoms.
Graduated pets live in animated kingdom habitats on iPhone and Watch — forest, meadow, or city skyline.
SEE YOUR JOURNEY
Tap your pet on iPhone to explore its full story: a 30-day activity chart, a mood river that flows through your days, and a mood calendar showing how your pet felt each day.
YOUR WATCH FACE,
YOUR PET
Nine complication styles keep your pet visible without opening the app: current mood, activity percentage, stage name, active days, pet name, or a progress arc. Mix and match to build the watch face you want.
Works standalone on Apple Watch — no iPhone needed. Syncs across your devices via iCloud, so any Apple Watch in your family can pick up your streak.
THE WATCHIE ENCYCLOPEDIA
Thirteen in-depth articles cover everything from getting started to the mood ring, evolution, and brain games. Fully multilingual — read it in your language, right in the app.
PRIVACY YOU CAN TRUST
