my boy told me today that there are a few apps out there for the ipod touch that can weigh things. like, say, grass. i browsed the appstore and read the reviews for these things, and the reviews are split about 50/50. some say the apps dont work for shit. others say you have to calibrate it the right way and it will work to a certain extent. im asking if any fellow RIU members have used their iphone as a scale? is it possible? i dont want anybody including myself to burn money on a piece of shit that doesnt work. so, any functionality to these apps?
