Quiver

Each day, a universal prompt is released to all users. Users can't see others' answer to the prompt until they answer it themselves. Once they answer, they enter into the daily timeline and can interact. 24 hours later, there's a new prompt & conversation.

Quiver is a social media app in which users answer a new prompted question each day. Users are only granted access to the feed after they have answered the prompted question which is new each day.
