This app is the best Webcam App I’ve ever seen, without paying or ads. Works fine with IPhone 8. If you want to use it with Skype, you have to download the newest version from Skype.com, because the version that you download from the Microsoft-Store isn’t the newest one and won’t detect the Webcam-App. A Cable connection possibility would be nice, but the WiFi connection works also fine, the phone just gets a bit hot, so I’ll recommend to turn down the brightness of your display and don’t charge the phone while using it as webcam, just charge the battery of your phone before. Kind regards and stay healthy.
