Social Jukebox, Tracktl lets users interact together with the music of a location on their smartphones. Tracktl is used as an event animation (parties, cocktails, etc...) and a venue soundsystem (bars, gyms, student cafeterias, etc...). Tracktl is a new media that reconnects venues and their audience : we give venues and events a new way to touch easily their customers (display informations on screens, user data management and customized mailing, etc...), at the same time as putting them in the center of a fun and innovative experience.
