Imagine this
You’re gearing up for a long-awaited trip across several U.S. cities—San Francisco, Los Angeles, and Las Vegas. You have a list of must-see spots, but every time you try to map out your itinerary, you find yourself tangled in connections, worrying you might miss out on the best parts.

That’s where our solution comes in—‘Multicity’. We built it to make planning your journey as effortless as binge-watching your favorite show: just a few taps, and all your flights, hotels, and even car rentals are right there on one screen.

One of our users, Michael, had a similar experience. He used ‘Multicity’ for his California tour and was pleasantly surprised by how easily he could tie all the stops together. “It felt like having a personal assistant in my pocket,” he said.

Now, planning a trip is no longer a headache but an exciting part of the adventure, allowing you to focus on experiences instead of logistics.

Testing and analysis
This service temporarily does not work
in your region!
We used the fake door method to test the hypothesis of how interesting and in-demand the Multi-City service would be for both current and new users. By quickly implementing this test, we were able to gather valuable data and insights. The results showed a significant interest in the functionality, indicating strong potential and demand for the service among our user base. This quick and efficient testing approach validated our hypothesis and provided clear direction for further development.
Fake door in UX design is a method for testing user interest in new features or products by offering them the possibility to use a feature that does not actually exist yet.
— Now live with that information.
