We understand the idea. The only usage we can imagine, sharing a private photo, seems way harder in this app than just passing someone your phone.

It seems like you don't understand the idea. This ensures that all parties consent to the content being viewed by any other party.

Does installing this app somehow disable the regular camera app? Not sure how it ensures anything.

Joe takes a picture. I want to see it. But, oops, Billy isn't here to complete the nuclear launch procedure. So I turn to Joe and say "hey, text me that funny picture of Billy." What happens next?

Well, probably the photo is supposed to be taken with the Hangover app in the first place. I don't know app development, but does an app that accesses the camera _have_ to store the photo alongside photos taken with the normal camera app?

My impression was: group of friends are in vegas having a "Hangover (the movie)" style night and agree to only take photos with this app. That way, come the morning they can all review them, but only when they're all together.

Obviously, if they take photos with their normal camera, or if all apps have to save photos to the filesystem and can be seen by the built in photogallery app, this doesn't work. Maybe the app uploads them to the Hangover site and then automatically deletes them from the phone?

It might work if they delete the original photos (if that's still possible on modern devices).

Or it could require you to manually delete the phone's regular copy of the photos, which your "friends" can verify since they're in the same room.
