The aforementioned DroidCam app is also available on iOS (freemium), so you can use your iPhone as a webcam for your computer. Once you install the app on your iPhone, you will have to install the “DroidCam Webcam” PC client on your laptop or desktop PC. It is available for Windows and Linux systems, but unfortunately, there’s no Mac client for now. The PC client, however, works with Zoom, MS Teams, Skype and most other programs.
