The app does a good job giving you info similar to the more complete looking desktop or laptop app. Any drop-outs people have had are due to the Internet feed from camera to plane to control room. This was not explained very well during the race. In many cases, excluding the day the plane could not fly, the problem was caused by the contracted provider of the link. It was explained to me as a problem with the local Internet feed. Everything had to go through that feed, narration, phones, video, GPS locations... the works. The problem is not with the app, but with the network. Hopefully, it will not happen next year.
