Ratings and reviews

I just spent the better part of two hours trying to find an Android application that would allow me to see video from a connected USB webcam. This was the only one that worked. Every single other application that currently exists on the Play Store only shows a black screen with a webcam. Now, I can set up the clamps and shave the back of my own neck. (Note that I had to buy a USB to USBc adapter capable of data flow.. most of the adapters only allow power flow and won't carry the video signal.)

Ad overload now, with full screen ads every 30s or so. It disconnects the camera with every ad, making it almost unusable now.

USB Dual Camera is a pretty good app, where some is kinda hard to work with web cams, this works pretty well. is a bit complicated because a average person ain't gonna know what have the settings even are, but they will be able to figure it out I would give 5 stars if it was easier to navigate.
