I am a chemistry student that has been running the notability app on several iPad generations. Currently I have an iPad Air 2 and the app works great with spilt screen, along with other features of iOS 9. I do plan on getting the iPad Pro due to the added benefit of using the Apple Pencil since drawing molecular compounds can be difficult with a standard stylus. I will say that I would love to see improvements on the zoom feature on notability as that would make drawing and handwritten note taking a lot neater. Also would like some natural looking paper backgrounds like grid paper for instance, oh and a ruler to draw straight lines that works with finger gestures would be fantastic! Please add that in developers!! Other than that, a near perfect app! Going to get it for my cousin when she starts school!
