Many young drivers do not feel very comfortable with their vehicle maintenance knowledge. Even though they rely on their cars daily, they're often unsure how to properly care for them.
Rollio empowers drivers with real-time warnings of vehicle issues, guides them through every next step of an issue, and indicates whether it's safe to drive or not to make vehicle maintenance much less stressful and costly.

Rollio is a mobile app that helps drivers better understand and manage their vehicle’s health.
By connecting to a small plug-in device called a OBD2 inside the car, the app provides real-time diagnostics and translates technical error codes into clear, plain english explanations.
Users are guided through what an issue means, how urgent it is, and what steps to take next to help get their car problems solved.

Why is this important to me?
I first began to explore the vehicle maintenance space after repeatedly supporting someone close to me through unexpected vehicle issues.
Those moments opened my eyes to how stressful and overwhelming maintenance can feel for many drivers.

Broadening my search
Broadening my search
I wanted to learn more about what other peoples experience was like with their car, so I interviewed 12 drivers about their experience with their vehicle.
To broaden the scope beyond interviews, I researched threads on Reddit, articles, and published studies to identify recurring themes.

After I conducted my user interviews and research, I had many strong insights that I turned into actionable steps.
These steps were crucial in ensuring that my app was solving the core problem that my users were facing, and that I had a foundation to build on.

Mapping and validating the journey
Mapping and validating the journey
I first conducted a card sort with ten users to understand their mental model of an app like this and use those insights to help me develop the app’s sitemap.
I conducted a tree test of 8 tasks to confirm users could perform the most common tasks in the app without confusion, and iterated on their feedback.

Interpreting user feedback
Interpreting user feedback
Based on the first task, the navigation to find details on vehicle issues was not as clear as I had thought before.
The agreement on paths for these four tasks was not completely clear either.
This test helped me realize I needed to simplify my navigation even more, and reduce the number of screens to complete certain tasks in the app.
