Just found both of these via Google (searched "blackberry metronome app"). I haven't tried it and don't know if it supports the Tour. It's listed at $18.60 but it looks like they have a free trial...
There's also one for $9.99 on BBAppWorld that supposedly supports all devices. It seems to have gotten horrible reviews... BlackBerry App World - Metronome

Instead of paying for a metronome application, you can copy mp3 files to your BlackBerry and play them for a range of beats.
For free regular metronome beats at different fixed beats per minute, go to reztronics.com and click "Metronome". Note that although the page says that these are for iPods, these files should work on any mp3 player including BlackBerrys.
For free music mixes at fixed beats per minute, go to djsteveboy.com and click "Mixes".
What's funny is that you can buy a whole new metronome device (software AND hardware) for much less than 19 dollars. The software should be less than 5.
