Correct.
An app that does the same as Go4 … but also brilliant for waypoint missions. Set the waypoints, set the POIs (points of interest), set the path and speed - and off it goes to film it all … very smoothly … or take pics … and a load more.
eg: Litchi mission - Felixstowe
… or this one that also has a screenshot of the setup in the app as well as the resulting video …
