As of 2011-07-25 this remains by far the best bpm tapper available. Automated BPM analyzers abound, but none have high accuracy with music that has no strong beat marker (drums, drum machine…). Blacktree's old app is the only tapper that displays BPM visually after you tap to the tempo, allowing adjustment before writing the data to iTunes.
If you know a way to get in touch with Blacktree, ask them to update their BPM Inspector for Lion!
