3D Touch is a pressure-sensitive touch feature introduced by Apple in 2015 with the iPhone 6s and 6s Plus. It allows users to interact with their devices in a more intuitive and efficient way by applying different levels of pressure to the screen. Unlike traditional touchscreen interactions, which rely solely on taps and swipes, 3D Touch introduces a new dimension of control, enabling actions like previewing content, accessing quick menu options, and enhancing overall usability.
How 3D Touch Works
3D Touch operates using a combination of hardware and software technologies. Apple’s capacitive touchscreens incorporate a grid of pressure sensors that detect variations in pressure applied to the screen. Along with the Taptic Engine, which provides haptic feedback, users receive a tactile response, ensuring a more interactive experience.
The feature primarily includes three types of interactions:
- Peek: A light press allows users to preview content, such as emails, messages, or links, without fully opening them.
- Pop: A firmer press opens the content fully after previewing it with the Peek gesture.
- Quick Actions: Pressing down on an app icon on the home screen brings up a list of shortcuts for fast access to commonly used functions.

Applications of 3D Touch
3D Touch was designed to enhance the user experience in various ways, improving efficiency by reducing the number of steps needed to perform tasks. Some of its applications include:
- Enhancing navigation: Users can access quick shortcuts and frequently used functions directly from the home screen.
- Efficient multitasking: By pressing the left edge of the screen, users could quickly switch between apps.
- Improved text editing: By pressing the keyboard lightly, users can convert it into a trackpad for more precise cursor movement.
- Rich media previews: Users can preview photos, links, and messages without opening them fully.
- Gaming functions: Some games utilized 3D Touch for pressure-sensitive controls, enhancing gameplay.
Why Apple Discontinued 3D Touch
Despite its innovative approach, Apple phased out 3D Touch starting with the iPhone XR in 2018, eventually replacing it with Haptic Touch, a long-press gesture that provides similar functionality without requiring pressure sensitivity. The decision to abandon 3D Touch was due to several factors:
- Complexity and Inconsistency: Many users found the varying levels of pressure sensitivity difficult to use, leading to inconsistent user experiences.
- Lack of Developer Adoption: App developers were slow to fully integrate 3D Touch functionalities into their apps.
- Hardware Costs: The additional sensors required for 3D Touch increased manufacturing costs.
- Device Design Constraints: Removing 3D Touch allowed Apple to create thinner and more efficient displays.

Alternatives and Successors
With 3D Touch gone, Apple introduced Haptic Touch, which provides similar functionality using long presses combined with haptic feedback. While Haptic Touch lacks the pressure-sensitive nuance of 3D Touch, it is far easier to use and understand. This shift allowed Apple to streamline the touch experience across all their devices, including non-iPhone products such as iPads.
Conclusion
3D Touch was an innovative feature that changed how users interacted with iPhones. While it introduced unique and efficient ways to navigate iOS, it ultimately proved to be too complex and costly for widespread adoption. With the introduction of Haptic Touch, Apple refined the experience, keeping many of the benefits while eliminating the need for pressure-sensitive hardware.
FAQ
What is the main difference between 3D Touch and Haptic Touch?
3D Touch relies on pressure sensitivity to trigger different actions based on how hard the screen is pressed. Haptic Touch, on the other hand, uses only long-press gestures combined with vibration feedback, making it simpler but less dynamic.
Why did Apple remove 3D Touch?
Apple discontinued 3D Touch due to its complexity, inconsistent user adoption, higher manufacturing costs, and limitations in device design. Haptic Touch replaced it as a more uniform alternative across the iPhone lineup.
Which iPhones had 3D Touch?
3D Touch was available on iPhone 6s, 6s Plus, 7, 7 Plus, 8, 8 Plus, iPhone X, iPhone XS, and iPhone XS Max. Starting with the iPhone XR, Apple transitioned to Haptic Touch.
Can I enable 3D Touch on newer iPhones?
No, newer iPhones do not have the necessary hardware to support 3D Touch. Instead, Apple offers Haptic Touch, which provides a similar experience using long presses.
Do apps still support 3D Touch?
Most apps have transitioned to support Haptic Touch instead of 3D Touch, ensuring compatibility with newer devices. While some older apps may still include 3D Touch functions, they will not work on newer iPhones.
