   ABSTRACT     = {The Android market is a place where developers offer 
      paid and-or free apps to users. Free apps are interesting to users 
      because they can try them immediately without incurring a monetary 
      cost. However, free apps often have limited features and-or contain 
      ads when compared to their paid counterparts. Thus, users may 
      eventually need to pay to get additional features and-or remove ads. 
      While paid apps have clear market values, their ads-supported 
      versions are not entirely free because ads have an impact on 
      performance. In this paper, first, we perform an exploratory study 
      about ads-supported and paid apps to understand their differences in 
      terms of implementation and development process. We analyze 40 
      Android apps and we observe that (i) ads-supported apps are preferred 
      by users although paid apps have a better rating, (ii) developers do 
      not usually offer a paid app without a corresponding free version, 
      (iii) ads-supported apps usually have more releases and are released 
      more often than their corresponding paid versions, (iv) there is no a 
      clear strategy about the way developers set prices of paid apps, (v) 
      paid apps do not usually include more functionalities than their 
      corresponding ads-supported versions, (vi) developers do not always 
      remove ad networks in paid versions of their ads-supported apps, and 
      (vii) paid apps require less permissions than ads-supported apps. 
      Second, we carry out an experimental study to compare the performance 
      of ads-supported and paid apps and we propose four equations to 
      estimate the cost of ads-supported apps. We obtain that (i) 
      ads-supported apps use more resources than their corresponding paid 
      versions with statistically significant differences and (ii) paid 
      apps could be considered a most cost-effective choice for users 
      because their cost can be amortized in a short period of time, 
      depending on their usage.}
