Ever wanted to practice your tempo precision skills as a musician, whether as a musical director, a pianist or guitar player? Easily create your setlists for your gigs and navigate through to practice individual tempi and tempo changes. You can use it live for an easy visual reference or when rehearsing. It is a matter of setting up your gig once and practising with low effort. A pro version is for sale with additional features (i.e. live mode, multiple sound packs, functionality to sharing setlists, and customization of the looks of the app).
