Earlier this week, and app developer by the name of Ryan McLeod took to Medium to tell a story about how he made an app called Gravity, which uses the 3D Touch technology on the iPhone 6S to measure the weight of objects placed on top of it. Unfortunately, when he submitted the app to the App Store for review, it was quickly rejected on the grounds that such an app had no place on the App Store. For whatever reason, Apple doesn’t seem to want developers to use 3D Touch in this way, which is a damn shame, because an app like Gravity could bring a lot of functionality to the iPhone.

Having only gotten there hands on it within the past month, many developers are still finding new and interesting ways to use 3D Touch on the iPhone 6s and iPhone 6s Plus, but Apple isn’t thrilled with all of the discoveries. Earlier this week, developer Ryan McLeod published a fascinating story on Medium detailing the creation of a working scale app. It’s worth reading in its entirety, but perhaps the most interesting part of the story comes after McLeod has overcome the technical hurdles to bring the app (aptly named Gravity) to life. On September 29th, four days after the launch of the iPhone 6s, McLeod submitted his app to the App Store for review. On October 7th, he received a rejection letter, but he was confident that Apple had probably mistaken his app as yet another joke scale app, so he took the time to put together a demo video to prove Gravity’s legitimacy. As it turns out, Apple hadn’t misunderstood McLeod’s app — the company just decided that “the concept of a scale app was not appropriate for the App Store.” There was no further explanation.
