> AirTags are different from other Bluetooth trackers like Tile because they rely on Apple's U1 chip to provide complete functionality. Functionality is limited in iPhones that lack the U1 chip, and it's even more limited in non-Apple devices. You need an iPhone, iPad, or Mac to set up AirTags because they require the Find My app that's only available for Apple devices. You also need an iPhone, iPad, or Mac to put AirTags into Lost Mode or find your AirTags on a map because both of those functions require the Find My app.
