Challenge

Missing Real-Time, Integrated Betting Experience

In sports betting, users must respond quickly to changing odds. Delays in receiving information or placing a bet reduce the user’s chance to secure favorable odds, and therefore affect revenue.

Allwyn needed a mobile application that would:

  • Deliver real-time betting data
  • Combine pre-match and in-play betting
  • Integrate multiple external data sources
  • Provide consistent performance across platforms
  • Scale for future product growth

Previously, users had to rely on slower, fragmented systems that made it difficult to react to odds changes or track outcomes efficiently. To stay competitive, Allwyn required a faster, more reliable mobile experience that could consolidate services and reduce friction.

Solution

Real-Time Mobile App with Multi-API Back-End

Adastra developed a native iOS and Android application that allows users to place and monitor bets both historically and in real time. The app delivers the same experience across devices and centralizes data flow by integrating five third-party APIs into a single back-end system.

This unified integration enables users to track and react to individual players, combine pre-match and live bets, and view past results within the app.

To support timely communications, Adastra implemented a dedicated push-notification infrastructure. This allows Sazkabet to distribute more than 100,000 targeted notifications within minutes, helping users respond quickly to events such as odds updates, match outcomes, or ticket results.

The application is designed to support ongoing feature expansion while maintaining stable performance during periods of peak activity.

Impact

Increased Adoption and Revenue

The Sazkabet mobile application has quickly become one of the company’s most important customer channels. Within 12 months of launch, monthly usage increased to tens of thousands of users, and approximately half of Sazkabet’s customer base adopted the app.

Turnover from the mobile application has surpassed the web channel, demonstrating its role as a primary revenue driver. This growth also helped Allwyn reduce the competitive gap in the Czech market by offering users a fast, responsive, and fully integrated betting experience.
