title: How to implement referral program in mobile Apps for both Android and iPhone
body: <p>We have a mobile app that's available in both Google Play Store and Apple AppStore, we want to implement a referral program to get more users to install and use our App. </p>
  
  <p>Here's the user story:</p>
  
  <ul>
  <li>Every new user (E.g John) is given to a unique referral link, where he/she can share to FB/TW/Email or SMS.</li>
  <li>When John friend clicks the link, they are directed to respective AppStore base on their device.</li>
  <li>The moment John's friend install the app and open the app, our server should get notified, and we shall know that the referral is from John, John will be rewarded accordingly.</li>
  </ul>
  
  <p>We have evaluated a number of Mobile App Install Tracking Tools, most of the tools are the best use in the Publisher/ Mobile Advertisement.</p>
  
  <p>Appreciate any comments, suggestions </p>
  
  <p>Cheers
  James</p>
