Bluetooth trackers are small tracking devices that can be attached to keys, purses, suitcases or other items. They are designed to help you track down lost items. Stiftung Warentest tested 24 trackers for Android and iOS. These included 19 tags or chips that are suitable as key finders, for example, as well as five trackers in cheque card format for your wallet...

With the SmartTag 2 and a newer Galaxy mobile, you can always keep an eye on your most important things. With this small gadget, you can locate your luggage when travelling, find your bunch of keys or track your cat when it's out and about on its own. Thanks to the ultra-wideband technology, you get a very precise route to what you are looking for.

Samsung's SmartTag 2 proved to be much better in the test: at close range, it locates misplaced objects just as quickly as Apple's AirTag. It is also waterproof. The best tracker for Samsung users! Catch: The proximity search only works with the Galaxy S Plus/Ultra model.
