Widzew







RTS Widzew Łódź is a Polish football club based in Łódź, founded in 1910. They have won four Polish league championships and the Polish Cup. Widzew is famous for its loyal fans who have broken 7 ticket sales records in Poland over the past 4 years. The app has been recognized by the popular Polish news website as the best sports team mobile application in Poland.
Challenge
The Director for Technology and Innovation of Widzew came to us with an idea for a mobile app for the sport's team. The goal was to connect with their fans through a new and effective channel in response to the growing trend of sport's club apps. It allows users to buy tickets for matches as well as easily and quickly find important information about their favourite team.
With the app, fans can
- keep up to date with daily news from the club, matches schedule and the current league table
- get to know the team better through pictures, videos and information about each player
- watch photos and videos from the latest matches
- listen to Radio Widzew (also working in the background)
- buy tickets for matches
Moreover, the app has some unobvious features. As almost all seats in the stadium have been purchased in the system of vouchers, we have included the possibility of giving up space for those who will not come, so that someone else can buy the ticket. Another great thing was the implementation of the live broadcast module and creating a map of the stadium using Geoeditor and the GeoJSON format.
Project's scope
We started our cooperation with workshops. Our client had a clear vision for the product and we wanted to turn that idea into a solid plan, understand his and app users' needs and choose the right tech solutions to make it all finely-tuned.
We were responsible for creating designs, native mobile apps for iOS and Android and launching the app on mobile stores. The backend was on the client's side and it required close cooperation to integrate all systems.
We’re still working together to update, support and maintain the app.
Solution
Widzew reached 1st place in the sports apps category and 10 000 downloads in the first week of launching in mobile stores. It reaches over 3300 active users every day.
Technology stack
Applications were written natively because at the point we started the development there were no popular good hybrid solutions.

Communication
In order to fully understand the needs of the club's fans we’ve been in constant communication with them and asked them what their requirements are. We have applied a long and extensive process of testing and defining the scope of the app’s functionalities by asking them to give hints on what they’d like to see there.
We’ve carried out the project on Trello. Then, during the maintenance we transferred to Jira. For day to day communication we use Slack. Thanks to direct communication with people responsible for the backend the development process ran smoothly.
After the app was released, our CEO attended the Widzew press conference to introduce it to the fans and talk about the project.
