OnSong has come a long way since it first launched in 2010 and is now the most capable app for live musicians. OnSong is now offering multiple products via subscription allowing you to choose different tiers of features to match your needs. If you've purchased OnSong from the App Store, you receive the same features as was previously available. These features are referred to as "Pro" features. For this reason, we've renamed "OnSong" to "OnSong Pro" to indicate this special status.
Now, a separate app "OnSong" is available on the App Store so you can unlock features using membership tiers such as Essentials and Premium. Both of these tiers require an OnSong Account and active membership to access. However, your OnSong Pro features and any add-ons purchases prior to this change will continue to be available.
