title: Tracking affiliate generated app installs in iOS greater than 24 hours
body: <p>I'm trying to run an affiliate project for my app and Apple's 24 hour cutoff makes it a bit difficult. I'm wondering whether there is a way to implement one's own tracking?</p>
  
  <p>I first was thinking a landing page with a phone number input form. Upon submission we'd use something like Twillio to send the user the app store link via SMS and also store the phone number together with the affiliates code from the landing page URL. I then saw that Google somehow let's you track adwords in relation to app installs and thought that perhaps there might be a way that doesn't involve this phone number indirection... Anyone know how they do it?</p>
