Tile app Let's start with the obvious points: Apple AirTag works with Find My, which is only on Apple devices. Samsung Galaxy SmartTag works with SmartThings Find, which is only on Samsung Galaxy devices. Both these trackers work within a walled garden: only Apple devices will locate the AirTag, only Samsung Galaxy devices will locate the SmartTag. Both of these networks are potentially huge as they are market leaders in smartphone sales - but there's a catch for Samsung. Pocket-lint Apple requires you to use an Apple ID for your iPhone (meaning there's potential for all iPhones to find an AirTag), but Samsung doesn't require the use of a Samsung Account on a Galaxy device.
