That is what I use to do. I wouldThat's basically my plan. Stream with my daughter's phone, record game on GoPro.
use my DD's phone to livestream via GC, and use GoPros to record the game, in order to make highlights.
Last summer we started using TagUp, which is great. I have a second phone that is set up to record clips during the game, controlled through an apple watch interface. Each at bat is recorded and uploaded in real time, using the watch to start and stop the video on each pitch. It's a service through her organization.
