Is there a reason why we shouldn’t use the URL from the QR code for your mobile phone on your laptop or desktop? It seems to work fine, bit irritating with where the camera is, but a USB webcam would solve that. The mobile app seems to work fine on my desktop.
No, should be fine. I think there might be some issues potentially with the browser dropping sensor data when the browser tab is not in front, but I think it’s a great experience.
