Michelle Rundgren (or company she involved in) is launching a vocal training app called VocalizeU
The app features a number of tools to help musicians with perfecting their vocal abilities including:
A Vocal Studio complete with microphone and mixer tools via a virtual “Home Studio” along with a journal and calendar apps to keep track of your progress.
A Vocal Recorder that allows you to sing over existing music in your library (karaoke mode).
A patented vocal evaluation will test your vocal abilities and offer suggestions on how to make it stronger using programmable scales.
Pitch training uses pre-programmed metronomes to get your timing just right.
