TECH SW is a lifestyle app with sports features that require integration with the Tech SW Smartwatch. After binding the watch, the app allows making and answering calls, receiving SMS, and notifying of missed calls. The notification bar message reminder ensures that the user does not miss any important events. The app also enables phone and SMS reminder functions, which require permission.

The app records activity data in real-time and summarizes weekly and monthly dynamic trend charts. It also monitors the user's heart rate and physical condition in real-time. The sleep cycle tracking feature helps the user stay energized. The app allows setting daily reminders to reduce sub-health, including reminders to drink water and sit for a long time. Users can set daily exercise goals and push themselves to achieve them. The dial market feature lets users select their favorite dial. The app also includes two-way search, which helps locate the phone or watch, and remote control of the mobile phone, including playing music, watching, and taking photos. The app records sports performance for 15 sports, such as cycling and running.

The app requires certain permissions to complete functions such as call notification, call receiving, and caller name display. It needs to obtain the user's call record and other relevant permissions (READ_CALL_LOG), but it will not violate the user's privacy to obtain this information.
