Uses its own camera app
As best I can tell, this is not just a remote shutter control for the native apple camera app. It has its own camera app which is simple, like there is no focus or exposure lock. It does take photos and sends them to my watch. I can limit its access to photos ive taken through the camera watch app. Naturally the requirement for internet access raises suspicion. I couldnt find the supplier on google but trust the apple store to have nothing bad on it :)
