Smart 지킴이2 is a powerful IoT application that enhances the core feature of location tracking for IoT devices. Developed by SKTelecom, this app utilizes a hybrid positioning system, which combines LTE Cat.M1, GPS, and wireless LAN to provide accurate and unrestricted indoor and outdoor location tracking. With Smart 지킴이2, caregivers can set up activity zones for the wearer and receive notifications if they stray outside the designated area. The app also allows for sharing the wearer's location information with multiple contacts if needed.

In addition to location tracking, Smart 지킴이2 offers a range of health monitoring features. Caregivers can access information about the wearer's heart rate, blood oxygen saturation, activity level, and sleep health. The app also includes a fall detection feature to ensure the wearer's safety. If a caregiver detects any concerning signs, they can quickly send a simple emergency message such as "I'm worried. Please call me" to the wearer. Alternatively, the wearer can easily request help by pressing the SOS emergency button on the device.

Smart 지킴이2 is a comprehensive monitoring service that provides peace of mind for caregivers and promotes the safety and well-being of the wearer.
