You can make a scale another way too, by using the barometer in the iPhone. You will need a ziplock or other airtight clear plastic bag, and an object of known weight for calibration.&lt;p&gt;You can measure the change in air pressure in the bag with your iPhone inside, and put your object to weigh on top of the bag (carefully balanced). There is a linear relationship between the rise in air pressure and the weight of the object on the bag (I tried this and it does work)</text></comment>
