It’s kind of like Instagram, but it picks a random moment during the day for you to take a picture. ( When you’re awake normally ).

When the app goes off you have 1 minute to take a picture. If you miss it you can’t post a picture anymore.

It’s a bit of a reaction against the perfect pictures you see everywhere and people having amazing lives all the time. You’ll see pictures in your feed from friends/family just chilling in front of tv. Sometimes it’ll be nice timing ( oh wow! Just when we’re at <beautiful place> and other times it’ll be when you’re having a movie night with your SO.

I say friends/family because AFAIK you need to be friends with somebody to able to see their posts.
