title: How to avoid piracy on iOS (and generally in mobile apps)
body: <p>I'm thinking about an App I would like to sell at .99$ on Apple App Store. Not so much, but I would like to limit piracy (or at better avoid it). </p>
  
  <p>What are your approaches or best practise in this field? </p>
  
  <ul>
  <li>Freemium (some features free, some others not) model?</li>
  <li>Encryption of some client/server comunication?</li>
  <li>Some sort phone detection (IMEI, whatever?)</li>
  <li>Antipiracy code library (if exists)</li>
  </ul>
  
  <p>I see piracy as a big concern for mobile developers, don't you?</p>
