"Feature Supported" isn't well defined here. jQuery Mobile's persistant footers are anything but persistant on iOS. That's a big feature for most UIs, and something Sencha Touch got right a long time ago. That poor support for viewport manipulations is lost in the rankings.

Instead of a Green/Orange/Red score for each platform, I think a letter grade or percentage of supported features would be better. Someone who hasn't developed with jQuery Mobile will think that since it has a green ranking for iOS, that they'll actually be able to make things that look like iOS apps. They won't (although iOS 5 should fix that issue).

This is somewhat misleading because it makes the false impression that these frameworks are mutually exclusive.

PhoneGap, for example, could be combined with Sencha Touch to get native functionality.

Came here to say this. PhoneGap in particular differs greatly from most of these frameworks.

Conclusion: They all suck.

We need a mobile framework that focuses on compatibility first and features second. Not a million clones of, "We can make HTML elements look like a shitty iOS!"

Most of these aren't frameworks. They are libraries of interface widgets that barely work.

The lack of MonoTouch/MonoDroid is the first thing that I noticed. While c# may not be everyone's cup of tea, it can be used to develop across iOS/Android/WP

This would be infinitely more helpful if it would also list the platform you can develop on - ie Linux, Mac, Windows.

I checked all the checkboxes and got the whole chart. In fact the entire site could be replaced by that chart?
