Twitter allows sharing of 140-character messages called tweets and is used more than other apps due to more timely news and easier sharing than Facebook or Instagram. On Twitter, profile pictures are called "avis" and cover photos are called "headers." Facebook Live allows sharing moments with friends and family but it is used less due to more drama and oversharing with family. Instagram is used to view photos or short videos between users and offers photo filters and ephemeral 24-hour slideshows.
