Jukebox Hero is a useful free app that's great for parties. With it, you can allow guests to DJ your party for you using shared music from your iPhone or Android phone.
The opening screen, shown here, illustrates the two main purposes of the app. You can either create a jukebox for your party, or guests can use their phones as remotes for an existing jukebox.
In the next few screens we'll walk through the process of setting up a jukebox.
