Atomic Sync: Digital Twin
Your anime digital twin
Free
Your twin grows with you. Walk, sleep and move, and data from the Apple Health app becomes XP that helps your twin level up and evolve. Now in Japanese.
Meet your digital twin. It evolves when you do.
Atomic Sync gives you an anime twin with a world of its own. Pick one of five twins, look after yourself in small ways, and watch your twin earn XP, level up and reach new forms.
HOW IT GROWS
• If you connect Apple Health, your twin earns XP from your steps, sleep, workouts and mindful minutes. The app also reads distances, flights climbed, active energy and resting heart rate.
• Care is for the small things: a glass of water, a bath, brushing your teeth. Check-ins stay on your iPhone and earn no XP.
• XP fills levels, and new levels bring new forms: four in all.
A WORLD THAT KEEPS YOUR TIME
Your twin's world follows the clock, from first light and the morning sun to evening light, the moon and the stars.
THREE TABS
• Avatar: your twin, its level and today's XP.
• Care: quick check-ins for the small things.
• Journey: your days and forms so far, and the next form ahead.
ON YOUR WRIST
The Apple Watch app shows your twin in the light of the hour, sent from your iPhone.
PROMPTS, ONLY IF YOU WANT THEM
Turn on a morning hello and an evening check-in in Profile. At most two a day, and none between 22:00 and 07:00.
YOUR DATA
• Apple Health is optional, and you can stop it any time in Profile › Privacy & data.
• Raw Health readings stay on your iPhone. Only a small daily summary is sent, so your twin can earn XP.
• No ads and no tracking.
• Export your data or delete your account from Profile at any time.
Atomic Sync is a game about your own habits. It is not a medical device and does not give medical advice. For people 18 and older.
