Ideating, testing and designing the wireframes (UX) for some key screens of their mobile app
A company whose main goal is to design, manufacture and distribute innovative charging systems to support the advent of sustainable transport. Wallbox aims to accelerate the change into a more sustainable way of transportation by providing a comprehensive, simple and effective solution for the charging issues among electric vehicles. With over 167 million euros in investment since its inception, Wallbox is positioned in several rankings as one of the Top 5 startups in Spain (2020, 2021), and continues its journey to make EV charging experience readily available across Europe.
Ideate, test and design the wireframes (UX) for the two main screens of the mobile application: Main Dashboard and Schedule
As a Product Designer, I identified improvement areas, created and tested the new wireframes and collaborated with the Wallbox design team.

We focused our efforts around “quick-wins” for the two main screens of the mobile application: 1.Main Dashboard and 2.Schedule. Our team worked together with Wallbox over a period of 6 weeks to carry out 3 different usability test iterations with an overall total of 20 participants.

Why are we here?
Identified areas for improvement and inform UX decisions about dashboard and scheduling.
New wireframe designs for the app (mobile) delivered in Sketch and InVision format.
We worked hand in hand with the Wallbox team.
We designed and executed 3 chronological iterations with an overall total of 20 participants in order to recurrently test and validate the different design approaches for Wallbox's app dashboard screen and schedule flow. Users were given a "traffic light" system, a simple and efficient method for ranking during the tests:
Red = Bad / Yellow = Neutral / Green = Good.
The following information is from the participants who took part in our usability test iterations. The objective with this sample pool was to be inclusive in regards to age, gender and tech adoption. Wallbox’s app must be easy and clear enough to be used by everyone.
In this first iteration we tested 5 proposals of the Main Dashboard screen and 2 proposals of the Schedule screen with 7 users.
In this second iteration we tested the 3 best valued proposals of the Main Dashboard screen and the same 2 proposals of the Schedule screen so that we could keep learning and improving the wireframes. This time the usability test was executed with 6 new users.
In this third iteration, the main difference from the other ones was that we implemented in the wireframes all the feedback we collected from the users from the other usability tests and we designed 3 wireframes proposals. In this case, we tested with 6 different users.
The following design proposal is our final recommendation based on the test results. This UX approach has tested positively in all iterations.
