An app designed to let moviegoers know when there will be a proper lull so they can run to the potty says it will be ready to go when Marvel fans attend "Avengers: Endgame" -- which is reportedly going to run just over three hours long.

The creator of the RunPee App tells CNET that fans typically should look for a scene in Marvel films that appears to lead up to a big battle. Regardless, creator Dan Gardner reportedly said the app will have “pee times” that will be spoiler-free and ready by opening night for "Endgame."
