There are a lot of wide ranging thoughts/opinions regarding whether or not gimbals/stabilizers (I will use these terms interchangeably) for ones smartphone are a high priority piece of equipment for IRL streaming compared to a tripod-style selfie stick. Gimbals utilize motors (gyroscopes) to stabilize the motion and allow for smooth tracking and panning. Thus it seems like it would be a natural fit for IRL live streamers. The reality is it depends highly on the equipment and actual situational use cases. Older stabilizers were large/bulky because they were designed with large motors. They were great for capturing really smooth footage...
