I still haven't been able to download the app for iOS.

The picture quality is good and it's easy to use. Highly recommended for those who exercise... The battery life is a bit disappointing.

The camera is decent, and the glasses are comfortable, but the image stabilization could be a bit better.

The glasses are very light, wearing them all day won't make you tired, and they won't shake while cycling

The lens is above the frame, providing a wide shooting angle
