Automobile app

Did competitive analysis on two automobile apps, Did user interviews with three participants for users' opinion on buying cars online,
I picked a user persona to empathize with,
I structured user flow to how my user can complete basic task using the app,
I used the user flow to map out low-fidelity wireframes,
I took it to next step by adding colors to the UI elements and typo face,
As the app was almost ready, I did a quick prototype,
Next was to conduct a usability test with three users again,
I found few things were missing and wrongly placed,
I analysised all the feedback from usability again,
I used the result for the design iteration.
