Groove! is a fun little metronome app for the iPhone or iPod touch. It was designed by Tom Reinert to be simple and fast as well as highly accurate. I’ve done the development of the app in January 2013. One of challenges of realizing Tom’s vision was to keep the timing of the audio output as precise as possible. I’ve achived this by using the AudioUnits technology of iOS CoreAudio framework.
