After the Yo one-word messaging app exploded with popularity, the developers behind Yo released Yo Lineup, an app for managing queues.

The app operates with more or less the same premise as the Yo messaging app, and it will let you know when a restaurant table or a waiting room is ready for you by messing you a simple "Yo." While Yo Lineup is a free service, in order to use it, you must have the Yo app and an account set up in order to receive a notification. The app has been installed millions of times, which could be a cost-effective alternative to buzzers or pagers that are used in doctor's offices and eating establishments.
