ZTFit is a lifestyle app designed to work in conjunction with smart wristband devices. The app establishes a connection with the wristband via Bluetooth to detect and assess user's exercise data, sleep quality, and other information. It aims to assist users in understanding and adjusting their lifestyle habits more effectively and conveniently.

One key feature of ZTFit is its ability to utilize GPS for tracking exercises. However, it's important to note that continuous use of GPS in the background can significantly drain the device's battery. Additionally, ZTFit seamlessly integrates with HealthKit, allowing for the synchronization of exercise data with the Health app.
