There are in-app purchases too?
Yes, there are. The version of OnSong you download does just about everything you could ever imagine to keep you organized on stage and in the practice room. We add some functionality that most people may not need, but that we think improves the app for some users. The development of some features takes time and effort and when you purchase an in-app purchase, it helps a small business continue to make and support the great tools we love to build for you.
