Hello, Has anyone ever run across an app for Android or iPhones that allows you to store a set of different tempos? Our drummer has been using an app for his phone to visually refer to the tempos for songs in our setlist. The trouble is dialing in new tempos between each song takes time. We don't need an actual click track or anything, just a visual reference of the tempo before starting each song. Anyone else know of an app that would help here? Or have any other suggestions?
