Time Guru Metronome 4+

Guitar Player Magazine says: "This ingenious super metronome was developed by funky-as-hell Sco sideman Avi Bortnick. It will leave out beats randomly to force you to strengthen your own inner time-keeping muscles, and it has other cool features for odd meters, drum machine-style patterns, and more... this is an awesome learning, grooving, solidifying tool."

Strengthen your inner sense of rhythm! Time Guru is the only metronome with the ability to mute its sound at random, in sequenced patterns, or both, so that you can assess whether you tend to rush or drag or loose your place with odd meters. Time Guru can periodically leave 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. It's like training wheels that sometimes come up off the ground.

Time Guru also features:
-the ability to play in different time signatures or sequences of time signatures
-create rhythmic drum-machine like patterns
-save presets for tempo, meter, sound and muting-
-35 loud sound sets;
-Human or robot voice counting in English, Chinese, French, German or Russian - great for teaching!
-tap tempo (5 to 300 BPM range)
-super accurate, rock-solid timing via a customized audio engine.

And of course it can function as a normal metronome.

NoTreble.com says: "I love the aesthetic and layout of Time Guru. It’s very simple and elegant. Time Guru also offers ability to set randomness of your subdivisions (great for testing your internal clock)….There is one thing that Time Guru does that I absolutely love, and for which, this app will always live on my iPhone – at the top of the screen, you will see a series of numbers (1-7). When you press a number, it is set first in a sequence and you can choose a subdivision that will then repeat that number of times (or set it to rest that number of times). Sound confusing? It isn’t, because the layout is so simple. Every time you press a new number, it is set next in the sequence and you choose your continue to choose your subdivisions."
