The Bluetooth tracker maker is adding free and paid SOS features to its products, including emergency contact alerts, silent alarms, and real-time location sharing. All products featured on WIRED are independently selected by our editors. However, we may receive compensation from retailers and/or from purchases of products through these links. Think of Bluetooth trackers and safety in the past few years and your first thought might be the misuse of Apple AirTags and similar devices against women in domestic abuse and stalking cases. Alongside collaborative initiatives to counter and shut down these malicious uses (such as the IETF's Detection of Unwanted Location Trackers, or DULT, standard), tracker makers themselves are flipping the script, turning tech that has been used to monitor women against their will into tech that protects them.
