Timing Rating Requests for Maximizing Obtained Rating

摘要

The number of apps available for download in leading app stores (Google, Apple, Windows and Amazon) has reached seven million in 2017 (according to statista.com), allowing users an ever rich selection in almost any possible category. The overwhelming number of alternatives available for each app complicates the selection process, as differences are hard to spot based on the long texts specifying the apps' description and included functionalities. Here, many find the app rating systems, that have become an integral part of almost any major distribution platform nowadays, to be of much help. These rating systems allow users to provide feedback on apps they have already downloaded and used, through posting a numeric rating (typically in the scale of 1-5 or 1-10) along with a textual review message. Indeed, user rating was found to be highly correlated with app downloads and is considered by many to be the most significant indicator to an app's success [12].
