People helps you organize and enrich your contacts beyond the default address book. What you can do: Create folder-based contact structure for fast navigation Import contacts from Apple Contacts Add your own nickname and notes to each person Keep your data synced across devices with iCloud Open linked Apple contact cards when available Show custom caller labels (folder path + nickname) on incoming calls via Call Directory Why People: Better structure than a flat contact list Extra context for every person Works alongside Apple Contacts, not against it Important: Caller labels require enabling the People extension in iOS Settings (Phone > Call Blocking & Identification). iOS controls call UI behavior, so labels appear when allowed by system rules.
