Revamping the City Guide app to provide personalized user experiences

Taking tourism to the next level by achieving higher user satisfaction.
the challenge
The existing app architecture was out-of-date and plagued by bugs, memory leaks, and frequent crashes. As a result, the app users reported having a less-than-desired experience.
the solution

Nagarro introduced new features, concepts, architecture layers, integration, and high-quality software, making the app user-friendly for tourists. We also implemented a CI/CD pipeline, ensuring a faster time-to-market for all additional features.


Some of the highlights of our engagement are:


  • We developed a native app for Android and iOS which acts as a digital city guide for tourists.
  • Based on a tourist's interests, the app personalizes the itinerary offering multiple areas of interest to choose from.  
  • The app also shows well-known sights, key information, and insider tips about Vienna to the tourists helping them enjoy an authentic local experience.
  • It accompanies walks to museums, modern architecture, and sonorous places as a digital service with an audio guide.
  • Tips are suggested based on the geo-location and interests, matched to the current position to provide the best event/places/experiences happening nearby.
  • The app also allows saving favorite places of interest by tourists to come to later as their discoveries.


the outcome

Software development and testing, together with UX and UI, were used to take “ivie” technologically into the future. It will be expanded with innovative features and services over the next few years.


Impact on the business:


  • Easy and seamless interface for users to personalize their travel and receive recommendations resulting in a better user experience
  • High user satisfaction as reflected in the app store rankings (4.8 on App Store and 4.6 on Google Play Store
  • The app has the scalability to incorporate additional features in the future to help tourists leverage all facilities/spaces the city has to offer.

“ivie” is the ideal companion on the smartphone for everyone who wants to explore Vienna and sets new standards in storytelling - it is not only interesting for guests but also for Viennese people. Nagarro is an ideal partner for further development, who was able to score points in the tender with a great deal of experience and extensive know-how.
