Data Analysis:
Research Questions
Methodology
Convenience: Users seek a car wash solution that fits seamlessly into their busy lives. They need a service that allows them to maintain their vehicle's cleanliness without disrupting their daily schedules. GoCar must provide an easy-to-use app interface for quick booking and flexible scheduling options, ensuring that users can access car wash services whenever and wherever they need them.
Reliability: Users rely on GoCar to deliver on its promise of punctuality and consistency. They expect accurate tracking of service providers, timely arrivals, and reliable completion of car washes. GoCar must invest in robust technology for real-time tracking and ensure that its service network is efficiently managed to minimize delays and maintain user satisfaction with dependable service.
Quality Service: The primary concern for users is receiving a high-quality car wash that leaves their vehicle sparkling clean. GoCar must prioritize excellence in service delivery by employing skilled professionals and utilizing premium cleaning products. Consistency in quality across all service appointments is essential to build trust and loyalty among users who value the appearance and maintenance of their vehicles.

Product user challenges
Users of GoCar may encounter difficulties navigating the app due to a cluttered or complicated user interface. This can impede their ability to quickly book a car wash and may discourage them from using the service.
Finding available appointment slots that align with users' preferred time and date can be a challenge, especially during peak demand periods or in areas with limited service coverage. Users may face frustration when they are unable to schedule a car wash at their desired time.
Extended wait times for securing a car wash appointment can be a source of frustration for users, particularly when they need a wash urgently or have specific timing requirements. This issue can lead to dissatisfaction and may result in users seeking alternative car wash solutions.
Locating and filtering car wash service providers based on specific preferences, such as service packages or add-ons, can be challenging for users. Simplifying the process of finding the right service option tailored to their needs can improve the overall user experience and increase satisfaction with the GoCar app.

🔍 Key Insights from Competitor Analysis
These findings helped define GoCar’s strategic approach, focused on user convenience, operational efficiency, and tech-powered service delivery.
Many car wash platforms don’t offer live tracking or service updates, leaving users uncertain about progress. GoCar addresses this by integrating real-time GPS tracking and step-based service status updates for peace of mind.
🧭 Lack of Real-Time Service Transparency
Competitor platforms often feature cluttered or outdated designs that complicate booking. GoCar introduces a modern, intuitive UI that simplifies navigation and enhances the booking experience from start to finish.
📱 Outdated or Generic Interfaces
Despite music being one of the most powerful tools for self-expression, no major dating app gives it a central role in matching or messaging. Users we interviewed expressed that sharing music feels “more intimate than sending a photo” — a missed opportunity we seized to make connections feel personal and real.
🤝 No Clear Trust Mechanisms
How might we...
Help users book a car wash in under a minute with minimal friction?
Build trust between customers and washers through profiles and real-time updates?
Reduce uncertainty by showing where the washer is and when they’ll arrive?
Design a flow that works just as well for busy professionals as it does for casual users?
Offer a seamless experience from service request to payment and feedback?
Make the entire process feel reliable, modern, and effortless?

🧠 How Might We Enhance On-Demand Car Care?
Low-fidelity screens were crafted to test user flow, placement of icons, and messaging structure.

🎨 Turning Ideas Into Reality
🔄 Home Screen Evolution: Before vs After
The first version lacked visual consistency and user flow prioritization. In the updated design, we focused on elevating trust, service discovery, and action clarity—offering a cleaner, more intuitive and location-aware car wash experience.
We introduced washer profile photos and ratings directly in the main feed to build instant credibility and help users feel more confident before booking.
🔵 User Trust & Social Proof
The new version brings location front and center, showing relevant washers nearby with real-time distances, helping users understand availability at a glance.
🗺️ Location Awareness
A dedicated search bar was added at the top, allowing users to quickly find services or providers—something missing in the original layout.
🔍 Search & Filtering Upgrade
💡 Findings
🧍♂️ Users hesitate to trust unknown washers
Participants expressed concerns about booking without knowing who's coming. They wanted visible reviews, ratings, and profile details before confirming.
📍 Location relevance drives booking decisions
Users said they were more likely to book when they could see washer proximity and estimated arrival time. Real-time maps improved their sense of control.
📱 Overloaded screens slowed decision-making
Testers felt the earlier version had too much visual noise. Simplifying layout and highlighting key actions helped them book faster and with more confidence.
Several users shared that seeing available washers nearby in real-time made them feel more in control and confident about booking. They preferred experiences that showed who, where, and when—rather than static listings. This feedback led us to prioritize location-aware interfaces and live availability to support faster, more trusted decision-making.
📍 Users want more local and real-time car care options
Working on GoCar taught me the importance of designing not just for functionality, but for clarity, speed, and trust. Building an experience that connects users with local services in real-time challenged me to think about how design supports confidence and decision-making. Collaborating with developers, stakeholders, and real users helped refine flows and simplify key interactions. I'm grateful for the feedback, conversations, and teamwork that shaped this product. These lessons will continue to guide how I approach every future design challenge.
