Protocol Tetrad is a free multimedia application developed by The Ashley Collections Inc. designed for iPhone users. This app enables users to connect their smartphones to a Tetrad drone through the drone's built-in Wi-Fi signal. The main features include recording videos and capturing images in real-time, allowing users to watch the footage instantly. Additionally, users can download the recorded media directly to their phone albums. One standout feature of Protocol Tetrad is the ability to control the drone through the app itself, eliminating the need for a separate remote controller. Furthermore, the app supports 3D playback for an immersive viewing experience.
