Need to work out the tempo of a track? Confused over the many possible ways to work it out yourself? Simply play the song, load this widget and start tapping!

BPM Calculator will be refreshed every four beats. It is that simple!

Automatic BPM calculators that process audio may seem very fancy and efficient, however they are prone to serious error and their success can vary wildly depending on the type of programme material used.

The only variable when using this widget is your ability to tap a steady beat!

Fat Calculator allows you to approximate your body fat percentage using a tape measure - even if you dont have access to fancy scales or men with calipers.
It uses one of three methods to do so - those used by the US Navy, the US Army and the YMCA.
Ive released this application as freeware. Im considering enhancing it with the ability to store your figures each time you measure yourself and draw pretty graphs telling you the changes in your measurements and fat percentage over time. If I do that, Ill probably charge a small amount for the application. Let me know if youd like this feature - and youd pay for it.
Enhancements:
- First release.
