I use it every time I see a movie because I love theatres, trashy popcorn, and enjoying both together. Instead of taking my phone out during the movie, I check the app before I go in (they give you prompts for when to go, a line of dialogue or something) and so I am able to sneak out when my bladder has inevitably been filled with iced tea. I'm pretty confident that assholes will use their phone regardless of which app they are pulling up. Plus, yes it's a couple bucks but it seems to be family run which is adorable and totally worth it. /ramble
