Sometimes the GoPro camera is located at difficult to reach positions so that it cannot be controlled directly. The classical way for controlling the camera in such situations is through an app (e.g. Camera Tools for iOS/Android). This again has the disadvantage that we have to eventually pull out the smartphone, unlock it, and start the app.
A more convenient way is to directly control the GoPro camera from a smartwatch. The goWatch app is exactly what we need: it allows you control basic functions directly with the Apple Watch from your wrist.
