Astropad Mini, the app that turns the iPhone into a graphics tablet for the Mac, is getting a major update today to add new features to the iPhone 6s and the iPhone 6s Plus. The new version of the app includes support for 3D Touch, enabling pressure sensitive drawing.

When using a finger or a stylus, the iPhone 6s or 6s Plus is able to detect 256 levels of pressure being on the screen, letting users draw thinner or thicker lines based on the amount of pressure that's applied.


For those unfamiliar with the Astropad line of apps, they're able to transform an iPhone or an iPad into a professional graphics tablet that can be used with the Mac by mirroring the Mac's display to the iPhone. The iPhone's touch controls are then used for creative tasks like editing photos and creating art with little to no lag. Because the app simply mirrors what's on the Mac's screen, it's compatible with any Mac-based editing app like Photoshop CC and Pixelmator.

The Astropad Mini app for the iPhone is now a free download, as is the Mac app, so the Astropad system can be used by anyone at no cost. The Mac app is available from the Astropad website and the iPhone app is available from the iOS App Store. [Direct Link]

I wonder how many articles we'll see here letting us know that apps have now got 3D Touch support.

Slow news day, hey? Surely not, Q4 earnings call is today.

This is a biggie. A drawing app that can sense 256 levels of pressure. It really shows off what 3D Touch is capable of.

I agree... even if I do have the wacom intros stylus... this is much better, partly because the wacom never f***ing connects!

"photoshopping with a toothpick is the FUTURE"

I though the The public APIs only gave limited pressure ranges? Are they using private APIs ?

There are two ways to use 3D touch:
1) Use the API that handles the "gesture" for you (UIPreviewAction, UIApplicationShortcutItem), to get Peek / Shortcuts
2) Use the UITouch object directly to get at the raw pressure information.

Apple even has sample code for #2.

This is the first app (to my knowledge) that actually supports 3D touch more than just popping up an alternate menu.

Also, Apple's Notes app supports 3D touch for pressure when drawing on the 6S(+). Not exactly something Apple went out of their way to mention.
