SingerPro

Singer Pro is a free teleprompter system especially designed for your Android phone or tablet.

It provides timers that allow you to sing and play an instrument at the same time. This is possible because you can configure each point that you stop singing and a guitar solo comes in, for example. At these specific times the screen freezes and after another setup timer the animation resumes from the last point, giving you complete control over every song without any interaction with the device during the performance.
