In Stockholm, commuters access public transport mainly through the SL app or with a physical card. Although the card can be topped up via the app, many still prefer buying tickets from ticket agents as their main method. Our goal was to identify behavioural barriers preventing users from going digital and to create a solution that moves at least 20% of commuters to use the app consistently.




SOLUTION

We redesigned the SL app to simplify how commuters buy and manage their tickets — turning a complex, confusing experience into one that feels intuitive, trustworthy, and effortless. Our solution focused on reducing friction, reinforcing confidence, and building motivation through small emotional cues that made the app feel more personal, human, and reliable.


ROLE

My contribution to this project was leading the UX research, conducting user interviews and collaborating on synthesising the findings to produce shared results. These provided the foundation for ideation and our rapid prototyping, during which I supported wireframing and UX/UI iterations. 

Built with Ann-K Friedrich, Ajitha Chellam, Ed Pelham, Massi Abibsi and Óli Hall. Completed in three weeks.





Approach

Sensing gaps: A complex ticket-buying experience


Stepping into commuters’ shoes, we conducted a service safari on the app and found the user flow overloaded with steps and descriptions, making the experience feel unintuitive and detached from real user logic.

In contrast, leading transit apps focus on simple key actions/positioning, such as “Buy Ticket” or “My Ticket”, making the experience feel personalised and focused right from the start.

Both early observations gave me the intuition that it’s not digitalisation that deters users, but the complexity of the digital process itself, which drives them to abandon the app and seek help from agents instead.

Extreme user research: Students or Senior Citizens?


Since complexity affects users differently based on confidence and habit, I propose that the team study the two extremes of the user spectrum — students and senior citizens. This contrast helped us identify which group to prioritise and revealed insights that could benefit all users in between.

We found that:
Students’ barriers are about usability + flow
Seniors’ barriers are about mindset + habits

From this understanding, students are at a higher leverage point for behaviour change because their issues can be solved through design and flow improvements rather than cultural change.

Synthesis

Key Insights: Buying a ticket on the SL app is harder than it should be, even for digitally savvy students


We conducted a mix of in-person and online surveys, primarily among 90% of transport users and 88% of student commuters, and the results validated our assumptions.

While comfortable with technology, students struggled with the app's complexity. The more friction they encountered, the quicker they lost interest and were less likely to make the app part of their routine.


How Might We improve a ticket-buying journey that feels engaging, efficient and intuitive, one that builds trust and fits naturally into commuters’ daily routines?

Ideation

To address these pain points, we used the Fogg Behaviour Model (FBM) to ideate solutions so that behaviour change can occur:

Behaviour = Motivation x Ability x Prompt

By viewing our insights through this lens, we identified specific moments where the SL app lost users because the experience wasn’t engaging, efficient, or intuitive enough to sustain trust and habit.

We mapped each solution to our design goals: Engaging, Efficient, and Intuitive.

      User Testing & Impact

      We tested 14 students with the following task: purchase a 30-day discounted student ticket in the app. We verified that the user flow was easy to follow and that the navigation was clear.

      SL client highlighted how our narrative effectively communicated the connection between research insights and design solutions, making the decision-making process transparent and easy to follow.

      They particularly appreciated our inclusion of seniors, the deselected persona, as it demonstrated thoughtful prioritization between extreme user groups and strengthened the logic behind our chosen direction. The redesigned flow comparison (old vs new) was noted as especially impactful in illustrating tangible improvement.

      The client’s feedback affirmed that our approach succeeded in making the SL ticketing experience more intuitive and trustworthy, while encouraging us to explore the onboarding concept further to drive greater adoption among non-app users.
