Surprised no one has mentioned http://www.appgyver.com/supersonic/ It's basically Ionic with at least SOME of the native speed gripes other comments are complaining about.

I agree that it's not going to meet native but in most cases it's _good enough_ and you are getting both platforms for free. If you can build for both platforms and don't mind learning native stuff then more power to you, but Ionic definitely has it's place. Until I see React Canvas reaching the maturity of Ionic, it'll have its place. I also hope Ionic works on mobile browsers as long as possible, because not many other mobile web frameworks match it.
