The vehicle controlling mobile application allows car users to know and m anage the status of the car at any time. The connection of the vehicle with the application is shown through the vehicle controls and telemetry data available in the application. The planning, processes and methodologies of the mentioned methods are descr ibed. The paper presents the methodologies and research plans with specific goals and hypotheses for each method. Also, the main features of the mobile app as well as target users are presented. This study has both qualitative and quantitative characterist ics. Testing results consist of data collected from 5 UX experts in the heuristic evaluation, 5 users in the usability testing and 33 participants in the desirability study. Analysis of gathered data gave insights into weak areas and places for improvement Consequently, the redesign of needed features was started. Testing hypothesis was confirmed so mentioned methods help validate the app's experience and uncovered areas users struggle with while using the app. Heuristic evaluation is a good starting poi nt for testing. Usability methods complete and verify the first method with users. The final touch is desirability, which shows the user's attitude toward the interface. Interface aesthetics benefits the brand to stand out among other competing brands but visual appeal also helps forgive minor hick ups in the app.
