How we built our app in 2 weeks using Ionic Framework
Mobile app is most most certainly going to be made using html and javascript in the time to come. Ionic and angular is great for building mobile apps with standard mobile UI elements like headers with back buttons and chevrons, pages that slides in from the side, modals and tab bars at the bottom of the screen. Everything is meticulously created in html, css and javascript. Scrolling is good enough for most usecases, but if your pages contains long list views with graphic elements the page starts to lag.However if you use famo.us' list view scrolling is nearly as fast and smooth as native code on iPhone 4. On newer phones to difference between hybrid apps and native is unnoticeable. At the moment famo.us only has low level components, like boxes with html content. Standard back buttons, chevrons, tabs, action sheets and icons has to be imported from elsewhere. Famo.us only does fast bouncy animations, touch events and 3d effects. Besides famo.us is working on their phonegap/cordova alternative wrapper.A combination of Ionics ease of use and famo.us' impressive speed would have been great. There's lot of promising little open source projects on github that either extends famo.us or integrates it with javascript MVC libraries.I believe Brendan Eich was right when he said "Always bet on JS!". I bet mobile app development is going to be dominated by JavaScript and HTML.
