The Smooth-4 Smartphone Stabilizer from Zhiyun-Tech, in black, has been designed to provide cine-style functions to content creators using their mobile phones for video capture. When used with the free, downloadable ZY Play app, the control panel enables Android and iOS users to control both gimbal and smartphone camera functions such as focus, zoom, time-lapse, and still photo settings. The Smooth-4's controls reduce the need to touch your phone's screen, thereby minimizing unintended jostling while recording.
