title: What are the features/technologies that native apps in iOS can use that web apps can't?
body: <p>I'm struggling trying to figure out if I should go native or if I should go with the web app approach for a particular project. I understand the benefits and the differences in approaches. The biggest question in my mind is what do I lose access to by going with a web app versus going with a native app?</p>
  
  <p>I know there are certain things WebKit can handle that used to be the domain of native apps only (i.e. access to geolocation information). I also know about different frameworks for adding this functionality, like PhoneGap. I'm not looking for any hybrid applications. I'm talking about differences between an app that runs inside Safari and one that is native Obj-C.</p>
  
  <p>Preferably, this will be iOS information and not Android information, but either would be interesting.</p>
