Audiodog: BPM Tap Tempo

Another iPhone app, this utility helps you determine tempo and delay times. Just tap the tap button in time to a track, and it outputs the tempo and delay times in milliseconds for whole, half, quarter, eighth, and sixteenth notes. It also has two alternate modes for dotted notes and triplets. A mixing lifesaver for those of us who like to use delays! It's only 99 cents and worth all 99 pennies, but if you're a cheapskate, there's a free app called Tap The Tempo, but its GUI is much less elegant, and it doesn't have as many delay times or the dotted and triplet options, so give the Audiodog some love.
