Improving usability of a mobile application. Case: Jaxber

Abstract

The purpose of this thesis was to evaluate the current version of Jaxber created by Nestronite Oy, and introduce another alternative technology that would have improved the usability of this mobile application.

Jaxber is a cloud-based mobile application that is available free of charge for the public use and it allows the users to connect to a predefined set of campaigns which may consist of multiple challenges in the form of video, audio, pictures, texts and qualitative and quantitative surveys. Jaxber has been used by hundreds of students in many countries such as France, Germany, Spain, Hungary, Slovenia, Poland and Finland.

Currently the Jaxber is developed by PhoneGap technology and is available for Android, iOS and Windows phone. However, the latest version of Jaxber which is built using PhoneGap framework has some imperfections that intend to be fixed using Flutter technology.

Flutter is an open-source technology that assists the developers to accelerate the development process of the mobile app, at the moment Flutter is widely used for mobile application development, but it might also conquer the desktops and web as well. Applications that are developed by Flutter can be complied to be used in almost any platform like Android or iOS.

To improve the quality of Jaxber in general, a new technology “Flutter” is introduced as replacement to PhoneGap and a new prototype of Jaxber is developed to help the future development of the application.
