What is gt1 pro?

As an AI language model, I do not have information about specific products unless provided context. However, "GT1 Pro" may refer to a fitness tracker watch or a TV box running on an Android operating system. For example, GT1 Pro is the name of a Bluetooth-enabled smartwatch that tracks fitness metrics such as heart rate, sleep quality, and steps taken. On the other hand, GT1 Pro TV Box is a streaming device that allows users to watch movies and TV shows on their television sets, run Android apps, and play games.
