PowerZoo — Your Battery Has a Life of Its Own What if your iPhone battery had a heartbeat? PowerZoo turns your battery into a living home for virtual pets. As your battery level rises and falls, your little companions react with new moods, movements, and personality. YOUR BATTERY, BROUGHT TO LIFE PowerZoo turns everyday battery moments into playful interactions. • Running low? Your pet gets tired, slows down, and may curl up for a nap. • Plug in your iPhone? Watch it wake up and react to charging. • Gaining energy? It becomes happier and more active. • Fully charged? It's time for zoomies. Your battery isn't just a number anymore — it's part of your pets' world. MEET THE RESIDENTS • Rabbit — the very first resident, full of expressions (and the occasional trip to the toilet). • Fly — zips across your screen and hovers mid-air, in the color you choose. • Seal — unlock it in Edit, then watch it hop around in your favorite color. Every pet has its own animations, behaviors, and personality. A PET WITH PERSONALITY Your pets don't just animate — they react. They may complain when energy runs low, celebrate when power returns, or simply have something to say about what's happening. Their behavior changes with your battery and charging state, so every visit feels a little different. PLAY WITH YOUR PETS Your pets have a playground of their own. Drag them around, tap to interact, or simply watch as they wander, rest, play, and explore on their own. There isn't one fixed animation loop. Each pet chooses from different behaviors based on its mood and energy, creating natural and unexpected little moments. A GAME WHILE YOU CHARGE Waiting for a charge just got more fun. • Match fruits and candies to cheer up your pet • Chain combos to build stronger candies • Jump into a game straight from Home PLAY WITH FRIENDS NEARBY Friends on the same network who open PowerZoo automatically join one shared room. See their pets roaming your stage, and challenge each other to Gomoku — tap "Play Again" for an instant rematch. If someone leaves, the room simply carries on with whoever's still there. YOUR ZOO IS STILL GROWING More animals are on their way, each with its own look, moves, and personality. Your battery may stay the same — but your zoo doesn't have to. SIMPLE AND FUN • No account required • No complicated setup • No ads interrupting your pets • Designed around your iPhone's battery and charging state Open PowerZoo, meet your new companions, and give that battery percentage a little personality. Plug in. Power up. Play together.

Kinma is a little companion that grows on real life, not grind. Photograph what you eat, and Kinma recognizes the dish and cuisine, then grows a little from it. Eat with friends by starting a table and inviting whoever's with you, and Kinma grows a different way, through connection instead of calories. HOW IT GROWS Every pet tracks two things: Nourishment, from the meals you log, and Sociability, from the tables you share. Which one you lean into shapes how your pet evolves. Eat solo and often, and it grows one way; gather people around a table often, and it grows another; balance both, and it finds a third form entirely. FACES Kinma remembers who you've shared a table with, building a quiet little archive of the people you actually eat with. Not a feed, not a follower count. Just a record of real meals with real people. NO GRIND, NO ADS Cosmetics unlock as your pet levels up. Kinma doesn't run ads and doesn't sell your data. SIGN IN YOUR WAY Use Sign in with Apple, Google, or an email and password, or skip all of it and just start. You can always add a real login later from Settings, from any device, without losing your pet. A pet that eats what you eat, and thrives when you eat together.
