iTapTempo is an application designed to let you tap a tempo, either without or with a sound playing at the same time. It's in other world ideal for remixers, who are in need of a short beat clock on their delicious vinyl grooves and other samples - as well as finding the tempo, you'd like for your song. It also functions like a metronome - from either the tapped tempo or a manually entered tempo. The metronome supports loading samples for usage in it.
