Metronome for firmware 2.0 and above

Couple weeks ago I bought a brand new metronome for $30. I wish I knew about this application for my iPhone:

Fully functional metronome. Include tap tempo feature, ranges from 30 to 250 BPM, 0 to 19 beats per bar, and has 9 selectable rhythms.

Avaliable for free via Cydia Installer. For 2.0 firmware and above.
