They notice patterns. Over time they develop their own quirks, opinions, and routines. Powered by on-device Apple Intelligence, every Peb’s thoughts and dialogue are generated privately on your device. No accounts. No servers. No tracking. Features: • A unique companion that evolves over time • Memories, rituals, and long-term personality growth • Adventures, discoveries, and collectible trinkets • Home Screen widgets, Lock Screen support, and Live Activities • Apple Watch companion app • English, French, and Spanish support • Private by design with on-device Apple Intelligence No two Pebs become the same.
