## What is PlugView?

Turn your iPhone into a monitor for your camera. One USB-C cable is all it takes: no recorder, no HDMI adapter, no extra battery.

PlugView shows your camera's live view full size on your iPhone and adds the field monitor tools you use to judge exposure, color and focus on set.

FREE TO TRY
The live view is free: plug in your camera and see right away that it works. All tools below are unlocked with PlugView Pro, a one-time purchase. In the demo you can try every tool before buying.
