title: iOS push to PHP usage app info
body: <p>after creating an iOS app which pulls data from a PHP server using JSON.</p>
  
  <p>I want to design an app which pushs data, send data related of the use of the app like:
  - days the app is used
  - time the app is used
  - who is registered on my app when is running
  - etc.</p>
  
  <p>Any experience to share? Some framework?</p>
  
  <p>Best!</p>
