Stores pics and videos on the glasses .. then you import them into the Meta View app. You don't even need your phone on or with you to take pics just to import them / view them on your phone.

Using my iPhone 15 Pro importing has worked 8 to 9 times out of ten. If the battery on the glasses is low it won't import the pics yet it's not clear why due to some bad design in the app (small and too much print telling you why it won't import).
