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.
