How to implement referral program in mobile Apps for both Android and iPhone

Question

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.

Answer 1

It can be done using Google Campaign Measurement where in the utm_source just give unique number/string for each user which you will receive when user's friend installs the app as Google Play store will broadcast it after the installation. Refer to this question.
