Bereal is great, you get a notification and take a picture, front and rear camera, that's all you get for the day, then you can see what your friends are up to.
I get it but man, I'd never want to post pics of myself on the Internet for anyone to see. I also don't think anyone would wanna see me anyway. ¯\(°_o)/¯
I mean like you take a photo with your rear camera and once that's taken it'll load up your front camera to take a photo but you can move it so it doesn't take a photo of you. Kind of like a countdown timer.
Must be an age thing. Mid 30's and I can't fathom why this is a thing based on the description in this thread. It just sounds so voluntarily invasive, like leaving your door open.
