5. The future is Hybrid
“While hybrid apps will be the majority of
enterprise mobile apps, web technologies like
HTML5 will make up the most commonly used
languages for building mobile applications by
2015”
-David Mitchell Smith, VP & Gartner Fellow.

6. Anatomy of a Hybrid app
• Deployed via a compiled binary
• Uses HTML5 for a portion of the UI
• Can integrate with native UI controls
• Features typically extend beyond what
HTML5 can do natively
