A full re-design of the Avis car hire app

I was responsible for the comprehensive redesign of the Avis car hire app, aiming not only to enhance the UI’s aesthetics and user experience but also to boost conversion rates. Leveraging Google Flutter allowed us to develop simultaneously for both Android and iOS, mirroring the successful strategy used for the Budget app.

The redesign involved extensive user testing to optimise the booking process. A clean, minimalistic design with abundant white space was employed to declutter the interface, focusing on presenting only essential information with options to access more details as needed.


  • Full UI redesign following branding and design guidelines
  • Full UX overhaul to increase conversion
  • UX Research and Testing
  • Project Management to ensure the app was designed and developed on time and to a high standard
  • To design and develop the app using Google Flutter and publish to both Apple and Android app stores.

My role

My design process

I meticulously apply the Triple Diamond design process to ensure exceptional product outcomes from ideation to launch. During the Discover phase, my approach involves comprehensive user research—utilising interviews, ethnographic studies, and competitive analysis to gather deep insights that inform the foundation of our design strategy.

In the Define phase, I take these insights forward, employing advanced prototyping tools and methods to iterate designs rapidly. This allows for effective validation and refinement of concepts, ensuring they meet both user needs and business objectives. My expertise in UX tools like Sketch and Figma, coupled with my ability to synthesize feedback, plays a crucial role here.

The Deliver phase sees me overseeing the final adjustments to the product’s design, ensuring every detail aligns with the established user requirements and quality standards. This stage involves close collaboration with development teams to guarantee that the implementation is seamless and that the final product resonates with the target audience.

Throughout these phases, my leadership is characterised by a proactive approach to problem-solving, commitment to excellence, and a deep understanding of user-centered design principles. My strategic vision and meticulous attention to detail ensure that we consistently surpass client expectations and deliver innovative, market-leading products.

The new Avis app

Available on iOS and Android now.

Designed around a truly contactless car hire experience.

Clear messaging throughout

We enhanced the Avis app to prioritize transparency, addressing customer concerns about hidden fees in the car hire industry. The app clearly outlines its functionality, all associated costs, and potential upsells right from the start, fostering trust and improving user experience.

Search results & progress tracker

The search results section has been completely redesigned, now featuring a new card UI that prominently displays each car’s features and transparently presents pricing upfront. Additionally, the updated progress tracker clearly indicates the number of steps in the booking process and maintains a running total of costs, ensuring no surprises at checkout.

Optional extras

The extras screen in the app has been thoroughly revamped to enhance transparency and customer choice. Recognising that car hire companies often generate significant revenue from extras, we’ve redesigned the interface to allow customers to easily select only the extras they need. For legally required items like snow tires/chains, clear messaging now informs customers of the necessity, ensuring all charges are understood upfront.

Managing your rental

The app now simplifies rental management, allowing you to handle everything without needing to contact customer service. Easily access all your rental details, utilise connected car features, and opt for early vehicle return directly through the app.

Contactless by design

Designed for a seamless user experience, the app facilitates a contactless rental process. You can bypass traditional queues, locate your rental via the app, and even unlock your car using your smartphone, streamlining your entire car rental experience.

Designing the User Interface

This comprehensive project involved designing a highly functional app using Sketch and an organised design system to manage its extensive features and requirements efficiently.

The app’s structure was meticulously organised into separate pages for each section, with Abstract employed for source control to minimise errors.

Additionally, all screens were interconnected to create a dynamic prototype that was used for testing, demonstrations, and as a developmental aid, ensuring a robust and error-free user experience.

Project outcome

Delivered on Time

Through meticulous research and planning at the project’s outset, we successfully launched the new app on schedule and within budget, despite the challenges posed by Covid-19. The app is now globally available on iOS and Android platforms and is achieving impressive conversion rates with customers actively booking rentals.

Future Proof

The design and development of the Avis app were carefully strategised to ensure it remains cutting-edge within the tech industry. It utilises Google’s Flutter technology, which supports rapid, cross-platform deployment to both iOS and Android, significantly enhancing development speed and maintenance efficiency. Additionally, an atomic design system was employed to facilitate swift modifications and innovations in the app’s functionality and aesthetic, enabling easy updates and scalability.

UI/UX Improvement

During the design phase, the Avis app underwent rigorous testing and refinements, resulting in a user-friendly interface that is both easy to navigate and efficient. This app was specifically developed with feedback from real-world Avis users, ensuring that the final product not only meets the expectations of our customers but also aligns with our business objectives, providing an exceptional user experience that enhances customer satisfaction and supports strategic goals.

New Tech

The revamped Avis app integrates cutting-edge technologies to enhance the overall rental experience:

Self Serve: This feature revolutionises convenience by allowing users to bypass traditional queues and manage their rental from booking to car access directly via their smartphone. This seamless process eliminates the need for physical check-ins.

Onfido: Modernising identity verification, Onfido enables users to confirm their identity and submit necessary documents through the app, significantly speeding up the verification process compared to traditional methods.

A few UI examples

This expansive project involved designing hundreds of screens and thousands of UI elements. Above are just a few examples of the screens developed. For a more comprehensive view, you can download the app from the iOS App Store or the Android Play Store today.
