Hey. We are group of creative people who developed bot script for iPhone.
Using this script you can install app many time on the same iphone. We optimised it and now install takes 2-3 minutes. Also we left some flexibility for several kinds of offers (like bot can complete registration on the site and then install app etc.).
Also bot can do retention for 3 next days. It's not flexible but you can change this behaviour programmatically.
So why I describe all these things? We gonna sell our bot script with admin page. Sure we will help to setup all stuff and provide detailed description of principles of working script and admin parts.
If you are interested, DM.
PS I can provide fresh statistics of CPI network where we tested our system
