Unfortunately not, Ink & Slide require a iPad (4th generation): iPad Air, iPad Mini or iPad Mini with Retina display.
I copied the hardware requirements from here: Technical specifications and requirements
I know it has almost been a year. I was wondering if this has changed or not. Is there a reason why Ink and Slide are not compatible with the iPhone 6 Plus? It is essentially the exact same OS and hardware. Why would a $5 stylus from Walmart work on ALL touch screen devices but a $125 Stylus only work with iPads?
What is the underlying restrictions that would prevent it from working with an iPhone?
Has there been any update regarding compatibility? would it work on a iPhone 6s / iPhone 6s Plus ??
Thanks in advance
