Many trackers include an app or remote trigger that makes your phone play a sound (often even if it’s set to silent). They may also send device-to-phone alerts such as vibration or screen flash so you can quickly locate a misplaced phone nearby.
Bluetooth trackers typically advertise short-range coverage in the low hundreds of feet (tens to about 100–150 meters). Examples in product listings range from around 250 ft (76 m) up to roughly 350 ft (about 105–150 m); actual range depends on model and surroundings.
Many trackers list water- and dust-resistance with IP ratings in the product details. Typical examples shown include IP67 and IP68 ratings, depending on the model.
Tracker apps commonly show a map with the item’s last known location, offer a ring/find sound to play on the tag, and provide network-based options like “notify when found” or location-sharing to help recover the item.
Trackers are designed to attach to keys, bags, luggage, and wallets. Some are thin enough to slip into a wallet, others include keyring holes or holders, and certain models offer built-in magnets or accessories for mounting.
Some trackers include precision locating that guides you directly to a nearby tag. Other models use Bluetooth proximity indicators or show the last-known location on a map to help you narrow the search area.
Crowd or network finding lets nearby participating devices anonymously detect a lost tag and report its location to the network, so you can see where it was found even when the tag is out of your Bluetooth range.
