The camera and lighting works perfectly as expected.
The app doesn’t actually save any photo or video. The picture button on the device works, and the app displays an animation that the image was stored. Yet, it’s nowhere. It doesn’t actually exist.
The only way to save a video or picture is with the iOS device itself. Take a screenshot or swipe down and tap record screen.
Unless they update the app and secure it do it doesn’t allow third parties to spy data, this is just a camera that won’t even save a picture.
