Tiny beads. Big smiles! Step into Bead Devil's neon-lit monster arcade and turn colorful beads into a pumpkin ghost, a witch cat, a one-eyed monster, and more. Explore 9 character patterns, preview each design, and save your favorites. On iPhone, choose a color and tap or drag to place matching beads. Hints, undo, bead removal, and reset tools let you create at your own pace. On iPhone, try a daily challenge drawn from the included patterns, collect a daily gift, and exchange in-game rewards for extra hints. Progress saves automatically on your device, ready for you to pick up where you left off. Bring the fun to your wrist: on Apple Watch, turn the Digital Crown to select a space, choose a color, and tap to place a bead. A close-up board helps you work on the little details. Play offline with no account required. iPhone and Apple Watch keep separate local saves; cross-device sync is not available in this version. Coins and gems are earned and spent only within the game, with no real-money in-app purchases. The app interface is currently in Simplified Chinese. Create your own little world of lovable monsters!

Your battery has a little friend. VoltPet is a pixel-art pet powered by your iPhone's battery. It bounces when you're topped up, yawns when you're low, and munches on electricity the moment you plug in. IT LIVES WHERE YOU ALREADY LOOK Your pet appears in the Dynamic Island and on the Lock Screen as a Live Activity, on the Home Screen as a widget, in StandBy while you charge overnight, in Control Center, and on your Apple Watch. IT REACTS TO YOUR REAL BATTERY Eight moods, from Energetic to Exhausted, all derived from the battery itself rather than from a timer. Plug in and the charging animation begins, with a haptic and a quiet chime. Reach 100% and your pet celebrates. IT GROWS IF YOU LOOK AFTER IT Charging your iPhone feeds your pet. Feed it on enough days and it grows from baby to teen to adult, and builds a streak. The last seven days sit on the home screen. IT HAS AN OPINION ABOUT BATTERY HEALTH Lithium-ion cells age fastest at the extremes. Past 80% your pet suggests unplugging; below 20% it asks to be fed. In between it stays quiet. IT RESPECTS YOUR BATTERY No timers, no polling, no background drain β VoltPet only wakes when iOS says something actually changed. Turn on Low Power Mode and your pet curls up and conserves too. BUILT FOR EVERYONE Full VoiceOver support, Dynamic Type up to the largest accessibility sizes, Reduce Motion, Increase Contrast, and a light/dark override of your own. Available in 11 languages. COMPLETELY PRIVATE No account. No servers. No analytics. No ads. No tracking. VoltPet contains no networking code at all β your battery readings and your pet never leave your device. VOLTPET PRO One purchase, no subscription, unlocks: β’ All five pets β cat, dog, bunny, frog and alien β’ Four seasonal costumes β Halloween, Christmas, Valentine's and Summer β’ Three more themes β’ Deluxe charging effects β’ A different pet on every widget
