Video demonstrates using 3D touch screen iPhone 6s to weigh objects, opens up new use cases

iPhone 6 scale

Developer Simon Gladman today demonstrated (via Jeff Benjamin) the use of the iPhone 6s display as a way to compare weights of an object, here denoted in a percentage of touch, on Apple’s 3D or Force Touch display.

The app called “Plum-O-meter” for obvious reasons is currently a jailbreak option for tinkerers. I think it is unlikely that this will hit the Official App Store because it likely makes private API calls to acquire the data. However, it does show yet another device the iPhone could one day replace. Full video follows.

Update: Huawei, which announced a “Force Touch” phone a few weeks before Apple, has a scale app on their phone. Hadn’t seen this, where’s the App Store app then?

    iPhone 6S: phone of choice for petty drug dealers. Hide your kids. Hide your wife. Phone the DOJ.

      And yet another reason the FBI & NSA will want a “Backdoor” into iOS. “We could arrest more drug dealers. We could save a child from a life of drug addiction — WE NEED THAT BACKDOOR!! Apple is enabling and promoting drug use.”

      FUD at its lowest. Stand firm and tall, Tim, don’t fall for the FUD. 👍🏼

  4. Hi,

    Thanks for the article! However, you say, “likely makes private API calls” – actually, the code uses standard public properties of the touch events and does nothing special at all. My blog post includes links to the source code to show how it all works.

    Thanks again,

    This doesn’t use any private API.

    The developer of this put its source code on github, and it doesn’t use private APIs. Getting 3D Touch data is public using a class called UITouch and methods touchesBegan and ended

    Huawei in early September weighed an orange on stage with its new smartphone, the Ascend Mate, so this “gimmick” is on its way to handsets as a use case in the near future.
