Challenge

The first major challenge was designing a car wash booking process with a strong focus on usability.

dditionally, I concentrated on creating a sense of satisfaction for users when they refueled or used tickets.

Another key aspect was crafting unique illustrations to enhance the overall experience.

Reservation flow

I utilized the ProtoPie app to design the reservation process at a high fidelity level, ensuring it closely resembles the final product. I rapidly iterated to create a prototype that promptly conducted tests for validation.

Testing revealed that providing a summary on the left screen, which folds the section after users select their time and options, resulted in a better user experience.

An interective Experience

Animations and interactions were incorporated into screens, not only in bottom navigation icons but also in refueling and coupon usage, to ensure users feel satisfied and entertained. This approach transforms routine refueling moments into a more enjoyable experience and injects fun elements through animations.

Illustrations

I crafted illustrations to establish the app's visual identity. They're isometric in design. These illustrations were used to provide a clearer explanation of the different services available within the app.

1. Night car wash (a service for those who wash their cars in the midnight)
2. Voice payment (a convenient way to complete refueling process simply by speaking when near a gas station)
3. mobile car wash (a professional service that uses specialized equipment to visit and wash cars, different from night car wash)
4. Detailing
