The original application presented frictions in user experience, such as not having complete accessible information from the dashboard, or lacking direct access to the only way to enter the parking facilities (the QR code)

BEFORE THE REDESIGN

The previous app made the core experience slow and frustrating, with no information at-a-glance and plenty of wasted space

Without a clear visual hierarchy, the home screen hid critical tools, buried in huge icons without highlighting any of them. Essential features like the barrier access code and active parking timers were treated in the same level as other less meaningfull options, creating an experience that felt slow and unpredictable. Mapping out these structural flaws was the first step towards designing a much faster, intuitive mobile journey with plenty information the moment you open the app

After the redesign!

Context & user needs

Interviews with a usual client showed the need to acccess core features and informarion quicker than what the app delivered

Core app journeys

Redesigned the app to provide instant access, ensure a frictionless checkout, and replace wasted screen space with useful information

Interface decisions

Used the wasted space of the icons to include usefull at-a-glance information, and kept the QR Access button always on the screen

Personas

Designing for urban mobility means serving two distinct mindsets: the rushed commuter who needs instant, one-tap QR barrier access and effortless payments from the home screen, and the city visitor who relies on glanceable tracking of their exact floor, spot number, or EV charging status

Real world context

Navigating real-world parking facilities means dealing with underground signal dead zones and time constraints. The redesign directly addresses these environmental roadblocks by prioritizing instant QR access that scans at the barrier. Whether renewing a monthly subscription on the go or checking remaining multi-ticket passes before approaching the garage, every transactional feature is streamlined for fast, one-handed operation under high-stress conditions

Constraints

To ensure the app remains highly functional in harsh physical environments, I developed a cohesive visual language based in components and strict accessibility standards, prioritizing high-contrast palettes and large, ergonomic touch targets for effortless one-handed use. By establishing a clear visual hierarchy, critical actions naturally dominate the screen, while modular components and comprehensive UI states guarantee a consistent, predictable experience across every step of the journey

Pain points

The original Interparking experience suffered from critical usability bottlenecks that directly contradicted the haste required in urban mobility. Primary features like the barrier entry QR code buried under many options. At the same time, the home screen wasted valuable real estate on huge buttons rather than offering glanceable updates on active parking duration, accumulated costs, or exact spot locations. Coupled with unclear multi-ticket management, the baseline app demanded excessive cognitive effort right when users needed simplicity and instant results
