In 2017 Trade eXpansion was chosen as app design and development partner for selfBACK (a EU Horizon 2020 project). SelfBACK has the aim to increase patients with lower back pains quality of life by to increase the quality of life for self management. Our task in SelfBACK is  designing and developing a smartphone application for both iOS and Android that can be used for a randomized controlled trial (RCT) in 2019.

Our primary focus areas in 2017 being the user interface and experience design, with the development of the application for iPhone and Android scheduled for delivery in 2018.


We wanted to really understand our users, so we started with basic user research, to get the idea of who the general patient is, and what their pains and everyday struggles revolve around.

The end result being an understanding of the users, together with an detailed user journey map, that would lay foundation for the further development.


Based on the user journey map we started work on different ideas that could be used in order to accommodate the general users needs, besides the general intention with the application. Based on general best practices together with previous experience and research, we came up with a wide range of features that could benefit the product.


Wireframes being the next step, as the start of visualization of all the research that has been done. As a low fidelity tool, it’s about getting the general layout and place of the different objects in place, rather than focusing on the color scheme and details.

During the development of the wireframes, the first prototype was developed, with the goal of getting an early indication for how the application would feel on a smartphone device.


After the overall layout has been agreed upon during the wireframe process, we start working on the general design of the application. This is an iterative process, where we go between testing and collecting feedback, and then make changes based on the feedback. Working on the general color scheme, tone of communication and the presentation of the individual element.
