Use Shou.
For anyone new to Shou: it's a screen recorder / live broadcaster that lets you record your DJI GO/Pilot, 3DR etc app flights to device or stream them live on the Internet for others you invite to watch live or later.
1) How to Live Stream the DJI Pilot App (on iOS) using the Shou.TV app:
2) The URL for iOS Safari browser installation of the Recorder app is
shou.tv/i
(You have to type that or paste that into your device Safari browser to install)
3) Then download the Shou.tv player app from App Store and create a free login.
4) Sample flight I've didn't see what it looks like:
Lake Cochituate
