Samsung opens SmartTag3 to iPhones, but some finding features stay Galaxy-only

The tracker adds cross-platform sharing, but some finding tools remain Galaxy-only.

Samsung's new Galaxy SmartTag3 can work with iPhones as well as Galaxy devices, extending the audience for its item tracker without making every feature available on every phone.

Announced September 30, the tag is smaller and lighter than its predecessor. Samsung advertises roughly 35 percent less volume, 33 percent less weight and up to 550 days of battery life under its standard-use testing conditions.

The cross-platform promise has limits. Samsung says Compass View, Ring Phone and Left Behind Alert are unavailable on iOS. Advanced distance and direction finding also depend on compatible Galaxy hardware.

Location finding beyond a direct phone connection relies on participating devices in Samsung's Galaxy Find Network. The tag's position therefore depends on the surrounding network of devices, rather than a continuous independent location feed.

Samsung's US announcement prices one tag at $29.99 and a four-pack at $99.99, with availability expected by early November. The global rollout begins in South Korea October 7, with additional markets planned for 2027. These schedules do not mean the tag is already on sale everywhere.

The launch also highlights a distinction that can be lost in the phrase cross-platform: being able to manage a tracker and being warned about someone else's tracker are separate functions.

Apple and Google rolled out support in 2024 for a joint industry specification for unwanted Bluetooth-tracker alerts, first proposed in 2023. It was designed to let compatible iOS and Android phones warn people when an unfamiliar tracking device appears to be traveling with them, even if it belongs to a different platform.

That system addresses the risk of a tracker being used to follow a person without their knowledge. Support depends on compatibility with the specification; the existence of iPhone support for an owner's tag does not, by itself, prove every cross-platform safety feature is supported.

Samsung's announcement should therefore be read at the feature level. It offers a broader way to keep track of belongings, but phone compatibility, finding tools, network availability and unwanted-tracking protection are distinct parts of the experience.

For households using both iPhones and Galaxy devices, the added support may remove an obstacle to sharing a tracker. The remaining trade-offs are practical: which phone supplies directional guidance, which alerts are available and how often nearby participating devices can relay a location. The smaller tag does not remove those ecosystem differences.
