As of May 2019.

Two cameras. The iPhone can be remotely controlled by my Apple Watch 3.

I’m trying to use voice control as much as I can for the GoPro.

• • • GoPro Hero 7 Black & USB to USB-C cable
      • MicroSD card
      • 3 extra Mibote batteries, charger, USB to USB-C cable
    • iPhone X & charging cable
    • GoPro 3-Way Grip, Arm, Tripod (VIDEO)
  • Miggo Splat tripod
  • ipow GoPro to iPhone adaptor
  • tzumi 12000 mAh battery & USB to Micro USB cable
  • Mophie 10000 powerbank & USB to Micro USB cable
  • Anker USB PowerPort+ 1 with Quick Charge 3.0 (fastest possible charge)
  • padded case for gear

I have GoPro attachments on both bike helmet and bike handlebars as well.  All mounts can attach either GoPro or iPhone.

What’s lacking most is the ability to ZOOM with either camera. I MIGHT carry a small camera with zoom, as well. I like zoom for distant animal sightings. And for Gymnastics.
