As a busy semi-pro juggling 6 regular bands plus many short-notice sub gigs, SLH has been invaluable to me since 2016. As of 2026 I've accumulated a catalog of 30 setlists (one per band I've performed with) and over 800 song charts. This data easily syncs between tablet, phone (if I forget my tablet), and the cloud. The dev is constantly improving the app, and provided personal assistance when I had an issue with data transfer to a new device (it wasn't the app's fault). This app is a gig-saver.
