I was just looking at this the other day--at first it looked pretty jank on my desktop chrome, but I switched to an android phone and the animations looked surprisingly slick. (Haven't tried on an iPhone yet.) I know the bar for purists is "it will never be native", which is true, but this is a huge improvement from the state-of-the-art mobile webapp frameworks/widgets from ~5 years ago. Definitely great to have options, especially for building/prototyping apps that otherwise wouldn't exist, e.g. because they'd be (for some/many developers) prohibitively expensive to MVP.
