Apple Pencil expands the power of iPad Pro and opens up new creative possibilities. It's sensitive to pressure and tilt so you can easily vary line weight, create subtle shading, and produce a wide range of artistic effects - just like with a conventional pencil, but with pixel-perfect precision. When using iPad Pro, there may be moments when you want even greater precision. So we painstakingly designed Apple Pencil to expand on the versatility of Multi-Touch. And while the technology inside is unlike anything we've ever engineered, picking up Apple Pencil for the first time feels instantly familiar. It lets you make any number of effects, right down to a single pixel, giving you more creative freedom than ever before. You may never have seen Apple Pencil before, but you already know how to use it. From the first moment, it does what you expect. And then far more. Whether you're sketching in the park, painting a watercolour portrait or drafting a blueprint, Apple Pencil gives you a variety of tools in a single instrument. You hold it, but it doesn't hold you back. The lightning-fast responsiveness of Apple Pencil separates it from other creative tools. That's because its latency - the tiny delay between when you begin drawing and the time it appears on the screen - has been reduced to an almost imperceptible level. iPad Pro knows whether you're using your finger or Apple Pencil. When iPad Pro senses Apple Pencil, the subsystem scans its signal at an astounding 240 times per second, giving it twice the data points it normally collects with your finger. This data, combined with Apple-designed software, means that there are only milliseconds between the image you have in your mind and the one you see on the display.
