Add voice commands for your GoPro cameras, e.g."Stop all cameras", "Start all cameras". I found myself cycling to work and leaving my cameras running, then their batteries would die, and when I would go to cycle home, they wouldn't turn on. With StopPro, you can set a Siri Shortcut voice command which will allow you say ~"Stop all cameras". Thanks to Siri Suggestions, your phone will suggest stopping your cameras at the regular time and place you usually do.
