Abstract：
This study empirically evaluates the functionality coverage of 18 mobile applications (apps) for Postnatal care including a recently developed app in Morocco \"Mamma&Baby\". This evaluation is based on a comparison of the COSMIC _ISO 19,761 functional size of these apps with the score obtained in a previous evaluation based on functions extraction through a quality assessment questionnaire. This comparison allows to discuss the relationship between the functional size of the 18 apps, their users\' ratings in the Play Store as well as the number of downloads. While for most of the assessed apps, there is only a small shift between the rankings of the two evaluations, for some apps, the shift is huge due to the number of features added and not covered by the score previously obtained. This study illustrates the use of COSMIC as an effective method for corrective or evolutionary updates since it takes into account all the functions and features of postnatal apps. For the \"Mamma&Baby\" app, efforts are required to boost the number of downloads, optimize its visibility, and attract the highest number of users.
摘要：
本研究通过实证评估了18个产后护理移动应用程序（应用程序）的功能覆盖范围，其中包括最近在摩洛哥开发的应用程序“Mamma＆Baby”。此评估基于对这些应用程序的COSMIC_ISO19,761功能大小与先前通过质量评估问卷基于功能提取的评估中获得的分数的比较。此比较允许讨论18个应用程序的功能大小之间的关系，他们在Play商店中的用户\'评级以及下载次数。虽然对于大多数评估的应用程序，两次评估的排名之间只有很小的变化，对于某些应用程序，由于添加的功能数量以及先前获得的分数未涵盖的数量，因此这种转变是巨大的。这项研究说明了使用COSMIC作为纠正或进化更新的有效方法，因为它考虑了产后应用程序的所有功能和特征。对于“妈妈和宝宝”应用程序，需要努力提高下载数量，优化其可见性，吸引最多的用户。
