Healthy Food Hertfordshire is an App and Responsive Website designed with social good at its core. It brings fresh, locally sourced products to every table in Hertfordshire, supporting the community and promoting healthier daily living.
Residents of Hertfordshire often need to travel to large supermarkets or rely on online orders, waiting for available delivery slots. Meanwhile, local farms and small producers frequently face the challenge of managing waste from fresh, organic products that go unsold.
Healthy Food Hertfordshire is a web app designed to provide users with a seamless experience for ordering fresh food in their local area. I worked on this project from Watford, with the concept developed to showcase innovative food delivery solutions across Hertfordshire.
Organising interviews, creating and refining paper and digital wireframes, developing low and high-fidelity prototypes, conducting usability studies, ensuring accessibility considerations, and continuously iterating on designs.
To gain a deeper understanding of the target user and their needs, I conducted User Interviews, which I later translated into Empathy Maps. This has generated suggestions on how the product could be produced, and we've seen that they all have a few things in common, including a difficulty to order, small window of time, little knowledge of app websites.
Furthermore, the results of the user study indicate that in order to create a smooth, efficient, and delightful experience, we must apply and concentrate on that crucial point almost effortlessly. adjusting the cost of each product to meet their needs.
Websites can often feel overwhelming, whether due to complex navigation or an overload of products.
Significant effort is often required to navigate and understand the layout of the App or Website.
Delivery time slots are often scheduled far in advance.

I mapped out Erika's user journey to address potential pain points and identify areas for improvement and development.
My primary focus was addressing difficulties with website navigation while keeping inclusivity and accessibility in mind. I aimed to create a smart, user-centered information architecture to enhance the overall browsing experience. The structure I designed was intentionally straightforward and easy to navigate.
Using a Progressive Enhancement Process, I created paper wireframes for every screen of the web app, addressing user pain points related to navigation, browsing, and time slot flow.
The Home Screen wireframe variants on the right are designed to improve and streamline the user's browsing experience.
The components of each sketch that would be included in the preliminary digital wireframes were indicated by stars.
I started designing for additional screen sizes to ensure the Healthy Food Hertfordshire Web App is fully responsive, providing an optimal experience for all users regardless of the device they use.
Transitioning from paper to digital wireframes made it clear how the redesign could address user pain points and significantly improve the overall user experience.
A key focus of my approach was prioritizing the placement of functional buttons and visual elements on the home page to enhance usability and navigation.
A series of images presented as a carousel will make the interaction engaging and easy to utilise.
From here you can access few important buttons, as well as the Social Media Links.
Hamburger Menu: Simple Navigation via those buttons to every page.
I combined all the screens involved in the main user flow (designed to navigate the page using all available buttons) to create a low-fidelity prototype.
At this stage, team members provided valuable feedback on aspects such as page organization and button placement. I carefully considered their input and implemented several recommendations that would enhance the user experience.

These were the primary conclusions that the usability study came to.
They found the Profile button difficult to locate, so they suggested making it more prominent for easier navigation.
The top navigation bar felt cluttered, so increasing the spacing between elements would improve the layout and enhance usability.
The Payment screen displayed an option to make a payment, but there was no section to enter payment details or save them for future purchases.
Offer the option of:
Click & Collect or Delivery from the beginning will simplify the process, also it would show items available in store
To improve the site's navigation, I implemented changes based on the findings from the usability study.
One key modification was extending the top navigation bar and increasing the spacing between elements for better clarity and ease of use.
Other improvements included adding imagery and buttons to better showcase the services offered.
The web app was designed with simplicity in mind, using clear icons, imagery, and titles to reflect the user flow.
These updates collectively provide a more intuitive and streamlined experience, making it easier and faster for users to find the services they need.
Building on my previous wireframes, I ensured that my mock-ups were optimized for a range of screen sizes. Recognizing the importance of delivering a seamless browsing experience across various devices, including mobile and tablet, I aimed to provide users with the best possible experience, regardless of the device they use.
The Hi-Fi Prototype adhered to the same user flow as the Lo-Fi prototype and incorporated many modifications recommended by my team members in addition to the design adjustments made during the usability study.
Inclusivity was at the heart of this project. I took intentional steps to ensure the app would be usable and accessible to a wide range of users, including those relying on assistive technologies:
Clear Visual Hierarchy
Buttons were paired with relevant icons and imagery to enhance clarity and aid quick recognition. Visual hierarchy was carefully applied to guide users through the interface effortlessly.
Use of Landmarks
I implemented navigational landmarks across the design to support structured browsing and improve accessibility for users of screen readers and other assistive tools.
Alt Text Integration
All imagery included descriptive alt text to enable a smooth experience for users relying on screen readers, ensuring no information is lost.
The final design resonated strongly with our target audience. Users appreciated the clear visual hierarchy, intuitive navigation, and engaging use of graphics, all of which contributed to a more enjoyable and accessible user experience. Feedback confirmed that the app aligned with users’ real-world needs—particularly for those seeking a streamlined shopping journey with inclusive design features.
This project reinforced the importance of user-centred design. I learned that even small adjustments in layout or interaction can have a significant impact on usability. The biggest takeaway was the value of continually returning to the user’s perspective—their challenges, behaviours, and goals—when making design decisions to create effective and meaningful solutions.
Continue testing the web app to uncover any gaps in functionality, improve user flow, and identify opportunities for feature enhancements.
Evaluate additional areas where the app can grow based on user feedback and business goals, then brainstorm and plan upcoming features accordingly.
Strategically update pages by adding relevant images, detailed information, and additional services to ensure scalability and long-term user engagement.
“Thank you for taking the time to explore my work on the Healthy Food Hertfordshire Web App Case Study.
I truly enjoyed working on this project and look forward to expanding it's features and learning more along the way.
I’m always open to feedback, collaboration, or simply a creative chat—feel free to drop me a message!
