Succeeding in Mobile Application Markets
Succeeding in Mobile Application Markets (From Development Point of View) by Ehsan Noei A thesis submitted to the Electrical and Computer Engineering Department in conformity with the requirements for the degree of Doctor of Philosophy Queen's University Kingston, Ontario, Canada September 2018 Copyright c Ehsan Noei, 2018 Abstract Mobile application (app) markets, such as Google Play Store, are immensely compet- itive for app developers. Receiving high star-ratings and achieving higher ranks are two important elements of success in the market. Therefore, developers continuously enhance their apps to survive and succeed in the competitive market of mobile apps. We investigate various artifacts, such as users' mobile devices and users' feedback, to identify the factors that are statistically significantly related to star-ratings and ranks. First, we determine app metrics, such as user-interface complexity, and device metrics, such as screen size, that share a significant relationship with star-ratings. Hence, developers would be able to prioritize their testing efforts with respect to cer- tain devices. Second, we identify the topics of user-reviews (i.e., users' feedback) that are statistically significantly related to star-ratings. Therefore, developers can narrow down their activities to the user-reviews that are significantly related to star-ratings. Third, we propose a solution for mapping user-reviews (from Google Play Store) to issue reports (from GitHub). The proposed approach achieves a precision of 79%. Fourth, we identify the metrics of issue reports prioritization, such as issue report title, that share a significant relationship with star-ratings. Finally, we determine the rank trends in the market. -

Ready Player One by Ernest Cline
Ready Player One by Ernest Cline Chapter 1 Everyone my age remembers where they were and what they were doing when they first heard about the contest. I was sitting in my hideout watching cartoons when the news bulletin broke in on my video feed, announcing that James Halliday had died during the night. I’d heard of Halliday, of course. Everyone had. He was the videogame designer responsible for creating the OASIS, a massively multiplayer online game that had gradually evolved into the globally networked virtual reality most of humanity now used on a daily basis. The unprecedented success of the OASIS had made Halliday one of the wealthiest people in the world. At first, I couldn’t understand why the media was making such a big deal of the billionaire’s death. After all, the people of Planet Earth had other concerns. The ongoing energy crisis. Catastrophic climate change. Widespread famine, poverty, and disease. Half a dozen wars. You know: “dogs and cats living together … mass hysteria!” Normally, the newsfeeds didn’t interrupt everyone’s interactive sitcoms and soap operas unless something really major had happened. Like the outbreak of some new killer virus, or another major city vanishing in a mushroom cloud. Big stuff like that. As famous as he was, Halliday’s death should have warranted only a brief segment on the evening news, so the unwashed masses could shake their heads in envy when the newscasters announced the obscenely large amount of money that would be doled out to the rich man’s heirs. 2 But that was the rub. -

Impact of Free App Promotion on Future Sales: a Case Study on Amazon Appstore
Impact of free app promotion on future sales: A case study on Amazon Appstore Harshal A. Chaudhari Department of Computer Science, Boston University, Boston, MA 02215, [email protected] John W. Byers Department of Computer Science, Boston University, Boston, MA 02215, [email protected] Amazon’s Free App of the Day program, aimed at improving app visibility using daily free promotions, is a compelling experiment in the ‘economics of free’. In this study, we investigate the longer-term consequences of free app promotions on the performance of apps on Amazon Appstore. In particular, we quantify the causal impact of such promotions on apps’ future download volumes, star ratings, and sales rank using a multi-level model. On average, apps see a surge in download volumes during such promotions, albeit accompanied by a short-term negative effect on its star ratings. On average, sales rank briefly improves but falls to pre- promotion levels within a few months. Interestingly, our findings suggest that lower ranked apps are the biggest beneficiaries of these promotions, as they witness the most significant sales impact. In addition, we show the presence of a cross-market spillover effect of such promotions on the performance of the same apps on Google Playstore. Our results underscore a nuanced set of trade-offs for an app developer: do the benefits of running a promotion and boosting ones’ sales rank warrant the lost revenue and risk of lower user ratings in the long run? Key words : promotion; mobile apps; marketing analytics; Amazon; Google; Android; electronic commerce. 1. Introduction The introduction of mobile devices such as tablets and smartphones has changed the way in which we work, socialize, and communicate.
