Apple is preparing a significant update to its location-tracking capabilities in iOS 27, allowing the Locator app to automatically switch the source of a user's geolocation data when the primary device is left behind.
Currently, the system operates in a rigid manner: users must select one device, usually their iPhone, as the sole source of location information. This setup means that leaving the iPhone at home results in the map incorrectly showing the user as stationary at that location, even if they have departed with another device.
With iOS 27, the algorithm becomes more sophisticated. When paired Apple Watch devices move a significant distance from the iPhone, the Locator app will begin transmitting coordinates from the watch. Once the devices are brought back together, the system reverts to the original source without requiring manual intervention.
The functionality will work with both standard Apple Watch models and those equipped with cellular connectivity. Watches with LTE support will deliver more reliable location updates, as they do not need to rely on nearby Wi-Fi networks or the presence of an iPhone.
Unified Locator App in watchOS 27
Alongside the iOS changes, watchOS 27 will retire the separate applications Find People, Find Devices, and Find Items. These will be replaced by a single, unified Locator app that features a full-screen map and an improved interface. Users will be able to switch between people, devices, and item tags using the Digital Crown on their Apple Watch.
Both iOS 27 and watchOS 27 are currently undergoing beta testing. The public release is scheduled for September, after which users will be able to leave their iPhone at home without losing accurate location tracking on the map.
