With the iPhone 6s and 6s Plus, Apple introduced us an entirely new way to interact with our phones: a hard-press gesture. As you may know, this feature was already available on the Apple Watch and MacBook under the name Force Touch. It — literally — added a new dimension to the user interface.
If you’re wondering why Force Touch was renamed 3D touch on the iPhone, you’re not alone. Shortly after Craig Federighi, who was also clearly baffled on the naming, presented this new capability, the first tweets arose. What was wrong with the Force Touch name? Too many Star Wars jokes?
But there is a difference! Apparently 3D Touch is more sensitive in the way that Force Touch can only detect hard presses, whereas 3D Touch can distinguish multiple levels of touches based on how firmly you press.
Though the change may seem unimportant, it allows developers to make more precise measurements on the iPhone. Take this app called Gravity for example that turns your iPhone into a digital scale with Force Touch. Though it was rejected by Apple for not so clear reasons, the idea is wonderful. So to show you how 3D Touch works, let’s try to make a similar app!
