Construct creates HTML 5 games, the wrappers and exporters export HTML 5, not true native apps. If you want to create native apps for a platform then most likely you will need to use the SDK or buy the Development tools that are built for that platform. Get an objective C development tool for iOS (and learn objective C). Get Visual Studio for Windows 8 and Windows Phone (And learn C#), etc....
HTML 5 is not a native or even a compiled low level language. HTML is not going to perform at the same level as driver level code on any platform. HTML 5 and Javascript are interpreted, procedural languages. Ranting about that fact won't change a thing. Construct is created by a two man team. The tool has specific goals and targets like writing HTML 5 apps. If HTML 5 doesn't meet your requirements, there is nothing Construct 2 can do about that. I wish McDonald's served the worlds best Lasagna which is also Zero callories and gluten free... but they don't. So that's not what I try to order when I go there...
Part of game design is looking at your target platform, evaluating your game design, and using the right tools to create what you want. There truly is no one size fits all solution.
If you are going to use any tool to create HTML 5 games, then you will have to get used to the limitations. Third party wrappers are not easy to create, that is why there are dedicated companies just for making them. That is what they are good at. They aren't making game design tools, they are making wrappers. Ashely and Co. aren't making wrappers, they are making game design tools. Since the wrapper developers are benefited most by having their wrappers and exporters used in as many scenarios and in across as many sets of tools as possible, they work to make their wrappers work with the various tools out there. But it takes them time, even though they know their wrappers and tools better than anyone.
Why not spend time whining about why the browser vendors or marketplace vendors don't make native wrappers for HTML 5 apps since they want your html 5 apps on their market place. Or why the browser developers don't make the browsers all support the same accerlation features to allow for performance across all of them without the need for all these third party wrappers...
Traditional game development meant creating versions of your game for each platform and working with multiple tools to target each one correctly. That story hasn't fully changed. While tools like Construct 2 make things easier to develop the game itself, unless Ashley and crew want to spend their full time making wrappers for all these platforms and ignore the core function of their tools which is game creation in HTML 5, then the best bet is to look at what wrappers that are out there and use them.
Notice that even the teams that are fully dedicated to writing these wrappers and accelerators take months or even years to get them into a state that works well for their platforms of choice, and they have much larger teams that the one working on Construct.
These are just the facts... They may be sad, but that doesn't change them.
