ABSTRACT Writing apps for children have been developed in recent year to support effective learning and writing skills of students. In this work, we perform a systematic review of all currently available apps for the operating system iOS and Android. We consider a number of newly release children writing apps by focusing on their features like the range of functions, target user groups, operating language, acquisition costs, user ratings and the connection between acquisition cost and user ratings. In total, we analysed 497 apps based on functions offered and their cost to users. In addition to the systematic review of apps, we also perform a participant-based usability evaluation of a representative sample i.e. 8% sample of the total collected apps. Totally 40 apps are selected for usability evaluation including 20 apps for iOS and the remaining 20 apps for Android. As a result of usability evaluation of apps, it is found out that with the increase in the number of functions in a mobile app, the usability of the app decreases. The subjective evaluation reveals that participants felt better user experience with iPhone in comparison to Android enabled devices.

为儿童编写移动应用程序的系统审查和可用性评估

摘要 儿童写作应用程序是近年来开发的，以支持学生有效的学习和写作技巧。在这项工作中，我们对 iOS 和 Android 操作系统的所有当前可用应用程序进行了系统审查。我们从功能范围、目标用户群、操作语言、获取成本、用户评分以及获取成本与用户评分之间的联系等方面考虑了一些新发布的儿童编写应用程序的特点。我们总共根据提供的功能及其对用户的成本分析了 497 个应用程序。除了对应用程序的系统审查外，我们还对代表性样本（即所收集应用程序总数的 8%）进行了基于参与者的可用性评估。总共选择了40个应用程序进行可用性评估，其中20个应用程序为iOS应用程序，其余20个应用程序为Android应用程序。对应用程序的可用性评估结果发现，随着移动应用程序中功能数量的增加，应用程序的可用性降低。主观评估表明，与支持 Android 的设备相比，参与者觉得 iPhone 的用户体验更好。
