The NookPhone is a smartphone the player is gifted by Tom Nook at the start of Animal Crossing: New Horizons, part of the Deserted Island Getaway Package. In game, Tom Nook explains to the Player that he had the phones made for every individual on the island.
Opening the phone allows the player to access the camera, Nook Miles, DIY Recipes, the map, Passport, the Critterpedia, the camera, Custom Designs, the Chat Log, the Best Friends List, and the ability to call other Players.
A unique feature of the phone is the ability to call a Rescue Service. If the Player uses the service, it allows the player to reappear outside their house/tent. Using this specific app costs Nook Miles, while all other apps don't.
