When you purchase OnSong, you are welcomed into a vibrant community of musicians and developers working to improve how you do music. Since OnSong is distributed through the App Store, updates are automatically installed by default. This means that you'll have the latest version of OnSong available to you. Since you may not want to update your app right before a performance, we recommend that you disable automatic app updates so you can choose a time that works best for you. This is a best practice when dealing with software and live production. You can then update to the latest version when you are ready.
OnSong is available as OnSong Essential and OnSong Premium memberships which are updated frequently with new features and services.
