<p>I have a problem. I am trying to build an application that will allow iphone to weigh any objects ranging from 40 to 200 grams. This application should not require the iphone to balance on your finger as other similar application does. So my question is that is there any feature available on the iphone that will help measure the pressure on the iphone screen? How should I proceed to build that application?</p>

<p>Here is the website link for similar application that I intend to build. <a href="http://www.youtube.com/watch?v=GtpgZCZdTjE" rel="nofollow">http://www.youtube.com/watch?v=GtpgZCZdTjE</a> </p>
