OnSong is a universal app available for iOS and iPadOS. You can install OnSong from the Apple App Store on your iPad, iPhone, or iPod touch.
OnSong runs on iOS 13.0 and higher. This means you'll need an iPad Air 2, 5th generation iPad, iPad Pro, or newer device with 32 GB*.
* OnSong consumes about 100 MB of storage space. Additional space is required for your library contents. This is usually relatively small and most libraries fit within a few megabytes. However, large imported PDF documents, backing tracks, and video backgrounds can consume additional space. If you are planning to use uncompressed audio or video backgrounds, more storage may be required.
