To collect more customer's review data, they wanted to give the opportunity for eH member the option to provide feedback via mobile apps and one of the logical spot to show that aspect would be via activity page as well as the user-profile. The app-ratings UI would be shown to a selective user.
App-ratings integrated into the activity feed. The main reason being that app-rating is an element that should be more of optional than something that's forced. By integrating into one of the main page, it aimed to incentive user to take action.
