@matigo I tried it with Zoom, QuickTime and Jitsi Meet, the latter is web-based & did not detect the Epoccam. It's supposed to work with Skype, too.
I use it on my iPad Mini 5 & iPhone SE. It's useless on the iPad 5th gen & 7th gen iPod Touch because they have pathetic 1.2 MP FaceTime cameras.
on iPads, it only works properly on the Air 3, Mini 5 and newer Pros than the original 12.9-inchers because of that 1.2 MP FaceTime camera.
