B-Track app analytics for September 13

The B-Track app can make calls between the phone and the child watch! This app is designed to work with the child watch and has the following main features: - **Reciprocal Calls**: You can make and receive calls with friends added to the contact list on the watch, so you can ensure the safety of children by rejecting calls from strangers. - Location Tracking**: View your child's real-time location to feel more at ease. - **Chat**: Real-time voice chat to communicate more comfortably with your child and make family relationships more intimate and harmonious. - Classroom Mode**: When enabled, the clock is limited to displaying the time and sending SOS signals, allowing children to focus on their studies without distractions. - **Virtual Barrier**: The app notifies you when your child enters and exits the areas you specify. - **Add Friends**: You can add friends from the watch interface, make calls and chat with added friends.
