In this project, I led the redesign of LUMO’s most-used feature: the Climb tab, where users spend over 70% of their time. Feedback showed climbers struggled to filter through climbs efficiently—an issue that created friction in their training experience. My primary focus was to streamline filtering and browsing, making it faster and more intuitive for users to find climbs that match their goals.

Designing ‘with’ users, not ‘for’ users
Our app usage statistics show that users spend a significant amount of time in the Climb tab, around 72%. When we gathered feedback from climbers about their experience in this section, it became clear that filtering through climbs can sometimes feel daunting.
To address this, we took proactive steps, collaborating with our users to create a more intuitive filtering system that helps them focus on what truly matters—climbing and enjoying the app.
During our workshops with the climbers, we created several wireframes that introduced new user flows for climbers, particularly in terms of filtering options. By utilising low-fidelity mockups from the outset, we could validate our assumptions early on and define the key functionalities required for the next iteration of the app.
The insights gathered from user interviews and app usage data enabled us to compile a thorough list of new functionalities required to enhance the user experience.
Essential features right at the user's fingertips
I redesigned the Climb tab based on the latest requirements, providing users with essential filtering options that enhance their browsing experience. The layout is flexible, accommodating various needs and ensuring smooth navigation through climbs.
The main screen filter navigation showcases a horizontally scrollable design with clear functionalities, making it simple for users to sift through climbing options.
The 3-state button provides quick filtering options, allowing users to toggle between Default, State 2, and State 3. This feature helps them easily find the climbs that interest them without lengthy filter forms.
Early testing results
We tested the redesigned Climb tab using an interactive Figma prototype. While it isn’t yet connected to the LED board via Bluetooth, we still gained valuable early insights from climbers through guided testing sessions and interviews.
What We Saw
Climbers report navigating the filters more confidently and said it felt easier to find what they were looking for
The scrollable filter bar and 3-state toggle were highlights—users called them “quick” and “clean”
Several climbers asked if they could save filter settings—a sign we’re on the right track but can go further
What’s Missing
Since the prototype isn’t live yet, we couldn’t track real usage or browsing time. That kind of quantitative data (like time-on-task or filter engagement rates) will be part of our next phase after connecting the app to the LUMO board. Some climbers also mentioned uncertainty about the button states and wording choices—it wasn’t always clear which filter mode was active. These insights point us toward exploring more intuitive iconography and customizable filter layouts in the next iteration.
What’s Next
We’ll continue improving the design based on community feedback, with a focus on:
Rolling out a functional version connected to the LED board
Gathering quantitative usage data to validate design impact
Exploring saved filters and smarter suggestions based on user habits
Scaling with the community in mind
With over 500 community-created climbs and more than 150 active users, we needed a systematic approach to enhance the UX of our app as we plan to introduce additional boards. The layout should be structured yet adaptable to accommodate various board types, LED interactions, and ensure a seamless user experience.
On the product side, we adopted Google's Material 2 design system, customising it to ensure visual consistency across our app while also optimising for Flutter development. This enables us to effortlessly execute Python scripts that communicate with the Raspberry Pi controller for the LED system used in the climbing boards.
These improvements are being gradually rolled out in close collaboration with the climbing community to ensure they effectively address user needs—while future updates remain in the pipeline as part of Lumo’s ongoing, adaptive design strategy that evolves with user feedback, software updates, and the growing number of climbing boards.
