Simply tap out a heart/pulse rate or tap in time to music or tap as a pendulum swings past and Tap Tool will calculate the following for you automagically... 4) Average time period between each tap on the screen.  At school, university or in the lab, use Tap Tool to time a swinging pendulum or oscillating spring in a science experiment or ANY periodic event.  As a health measure, you can use Tap Tool to quickly measure your heart rate or breathing rate.  Ask Tap Tool to tell you the beats per minute of a favourite music track.  In a survey you could use Tap Tool to count things/people/events/cars without using a pen or needing to look away.  The Tap Tool does all of the hard work while you tap on the screen of your iOS device.  Download the app, interact with its simple interface and see what YOU can tap to...  Learning to play a new tune?  If there's anything you'd like added to the app, contact us via our website.  We hope you enjoy using Tap Tool, and please let us know of the most bizarre thing you have used it for.
