Tap an egg, meet a tiny baby and raise it right on your iPhone: in the Dynamic Island, on the Lock Screen, in StandBy and in widgets. Feed it, bathe it, play with it and watch it grow up. It never dies and never makes you feel guilty. HATCH IT AND WATCH IT GROW • Tap the egg until the shell cracks and your baby pops out • It grows from baby to child, teen and adult, celebrating each stage • As an adult it shows a personality shaped by your care: playful, cuddly, foodie or sparkly EVERYDAY CARE • Drag food right to its mouth and watch it munch with puffy cheeks • Clean up little poops with one tap • Rub it with bubbly foam at bath time • Pet it, tickle it, boop its nose • Tuck it in and turn the lights off for a starry night PLAY TOGETHER • Playroom mini-games: Which Way?, Catch the Snacks, Pop the Bubbles • Teach tricks with praise: a big jump, spin, bow and dance • It dances along when you play your music COINS, SHOP AND ALBUM • Earn coins with daily tasks and open a gift box every day • Buy treats, toys and decor for the room • A memory album keeps the hatching, every stage and each learned trick IT LIVES ON YOUR IPHONE • Sleeps on your schedule and wakes up with you • Celebrates your step goal and hides from the rain • Curls up on the charger and puts on a tie before a meeting • Feed, pet and play from the widget or the Live Activity without opening the app NO GUILT, EVER Your creature never dies and never runs away.

Gentle reminders are cheerful, and skipping one changes nothing. PICK YOUR FRIEND Puff is a warm fluffy ball, Drop is a calm little slime philosopher, Chirp is a quick curious spark of a bird. Dress them in hats, scarves and new outfit packs, and preview every item on the Dynamic Island, the Lock Screen and widgets. VISITS Send your creature to a friend for an hour.
