Delimobil / 2019–2020
Clarifying five car-sharing trip states
In the existing Delimobil app, booking, driving and waiting looked too similar. Some people missed when paid time started or thought they had ended a rental when they had only paused it. This was a design problem that could cost people money.
Project scope, not post-launch results. Design approved for development; full release unconfirmed.
My contribution
As Lead UX/UI Designer, I helped redesign the trip flow with three designers, three product managers and nine engineers. The team used prototype tests, support-distributed surveys and sessions with new and existing customers.
Key decision
We gave each trip state its own priorities instead of keeping every control on screen. A swipe revealed more detail and returned people to the map. Fare selection got a dedicated space with room for more options.
Outcome
The redesign was approved for development. Some elements later appeared in the existing app. I left before I could verify the full rollout; release status and business impact remain unconfirmed.
Constraints behind the design
Important actions were hard to find, fare selection had room for only three options, and checking fuel meant another tap. We needed a structure that could handle more information without crowding the map.
Am I parked, waiting or still paying?
Selecting a car, free booking, paid booking, an active trip and paid waiting shared nearly identical visual structures. People missed when paid time began and sometimes put a car into waiting when they thought they had ended the rental.
Hidden actions, limited fares and an extra tap for fuel
Key actions sat below the visible area. Fare selection could fit only three options, and fuel levels were hidden behind map pins. A visual refresh would not solve that—we needed to rethink how the information was organized.
Testing trip states, failures and access to support
We combined competitor research with quick prototype tests, surveys shared by support and interviews with new and existing customers. We tested difficult situations too: an app failure, an unlocked car and the need to reach support.
Show the next action without crowding the map
Each trip state showed the information and actions needed at that moment. Swiping up opened more detail; swiping back returned to the map. Car markers showed the model and fuel, and a dedicated fare view gave us room for more options.
Approved for development; full release unconfirmed
The comparison below shows the shift from nearly identical screens to state-specific actions and costs. The redesign entered development; some elements later appeared in the existing app. A full release and post-launch results are not confirmed.
