Power in the palm of your hands

When flying, whether for business or leisure you want a smooth, stress-free journey to and from the Airport. Working closely with Govia Thameslink Railway, Assertis have made your journey planning simpler, hassle free and for the first time - combined plane and train.

The new Gatwick Express apps allow you to pin your flight to your dashboard to keep you up to date with the status of your train and plane!

User experience


Assertis UX team initially created user flows as sample cases of how users logically move through the GEX app in order to achieve a specific task.

By visually deconstructing these steps, we ensure full visibility of functionality required at the earliest possible stage in order to ensure there is a thorough understanding of user interactions and movement through the app.

Gatwick user flows


As a natural progression to the user flows, the next step was to start working up a set of medium fidelity wireframes. These set the tone for the overall content placement of the content – we looked at a full scope of wireframes from the dashboard to the content pages to ensure no time was wasted experimenting with high fidelity creative when exploring options.

Creative design

User interface

Gatwick Express has had a significant makeover in the last 12 months, so it was important to reflect the clean, elegant style of the relaunched brand.

Crucial to the success of the project was retaining the aesthetic of the family of apps launched by Go-Ahead as part of their digital offerings across the transport network.

Assertis created new and unique designs for the live flight section and ticket purchase process, including new icons, user interface details and interactions.

The product

Our toyfully named live data blender takes information from Gatwick Airport flight departures, National Rail Enquiries live departure boards and other rail sources to combine them into single view of performance and reliability over the network.

The user experience needed to be consistent and seamless across a varied set of data sources so we created an API that integrated a mixture of other APIs and event streams to provide a complete and consistent picture.

Development flowchart

We used separate native code bases to get a truly native feel that’s familiar to respective Android and iOS users. A common use case of our apps was passengers in a stressful situation at the station. A need for information quickly and reliably is paramount so we made sure to performance test the mobile applications and APIs to get the best experience for users.
