Experiences and Results of Applying Tools for Assessing the Quality of a mHealth App Named Heartkeeper.

Currently, many incomplete mobile apps can be found in the commercial stores, apps with bugs or low quality that needs to be seriously improved. The aim of this paper is to use two different tools for assessing the quality of a mHealth app for the self-management of heart diseases by the own patients named Heartkeeper. The first tool measures the compliance with the Android guidelines given by Google and the second measures the users' Quality of Experience (QoE). The results obtained indicated that Heartkeeper follows in many cases the Android guidelines, especially in the structure, and offers a satisfactory QoE for its users, with special mention to aspects such as the learning curve, the availability and the appearance. As a result, Heartkeeper has proved to be a satisfactory app from the point of view of Google and the users. The conclusions obtained are that the type of tools that measure the quality of an app can be very useful for developers in order to find aspects that need improvements before releasing their apps. By doing this, the number of low-quality applications released will decrease dramatically, so these techniques are strongly recommended for all the app developers.
