BeReal. I love that that the essence of the app, if used correctly, is to be real. To show what you're up to in the moment rather than a post that's performative or a perfectly curated moment. I also really like the sense of community, when the notification goes out and everyone posts within the two minutes given for an "on time" post, it's really cool to see what you're friends are all up to in that same moment-especially when you're so far from them and living such different lives.
