Outdoor-safety tool has already aided 272 rescues since January 2024 and will receive major upgrade in December
Hong Kong’s police force is preparing a significant upgrade to its “HKSOS” mobile application this December that will introduce live location sharing for groups and increase the number of emergency contacts users can designate.
Since its launch in January 2024, the app has been credited with aiding the rescue of 272 people.
Senior Superintendent Swalikh Mohammed of the Digital Policing Services Bureau reported that the app has achieved 150,000 downloads to date and that all search-and-rescue missions involving the app so far have been completed without prolonged delays.
The current version allows users—particularly those engaging in outdoor activities like hiking, paragliding and canoeing—to alert the 999 emergency call centre with a single tap.
An upcoming feature upgrade will enable users to form groups of up to ten people and track each other’s locations in real time throughout a journey.
Another enhancement is the further deployment of the patented “Signal Radar” technology, which allows rescue teams to pinpoint a user’s location even if the mobile device lacks signal reception.
Rescuers may use the radar on helicopters or drones in terrains where conventional telecoms coverage is unavailable or unreliable.
The new version is part of the police’s broader push to boost outdoor safety in Hong Kong’s challenging terrain and strengthen the connection between digital tools, live rescue capability and community involvement.
The force is also increasing public education efforts to raise awareness of the app’s features and promote its relationship with designated emergency contacts as part of its “outdoor safety-first” initiative.
With the upgraded functionalities, the app is expected to enhance response times and coordination among users and rescuers—particularly for remote or signal-poor areas—and broaden the safety net for both individuals and small groups engaged in outdoor recreation.
