Metronome for iPhone/iPad
Time Guru also features:
Develop your inner sense of time, meter and groove with Time Guru. Developed by rhythm guitarist Avi Bortnick (John Scofield Band), Time Guru is the only metronome with the ability to mute its sound at random, in patterns, or both, so that you can assess whether you tend to rush or drag. Time Guru periodically leaves you on your own so that you strengthen your own internal sense of time, rather than relying on the constant, rigid, external time keeping of a metronome. Sometimes the training wheels should come off! It is the ultimate tool for becoming a rock-steady, time guru.
