The fashion industry is constantly changing. Today's customers expect more than just beautiful clothes—they also want to be engaged digitally. That's exactly why tredy Fashion, a fashion retailer with around 160 stores in Germany, has completely revamped its app in collaboration with BNO Technology Solutions.
In this article, we show how tredy Fashion mastered the challenges—and what lessons other retailers can learn from this experience.
The starting point: an app that was no longer competitive
The previous tredy app was technically outdated and did not offer modern features such as loyalty programs or personalized offers. At the same time, customer expectations were rising:
- More convenience when shopping
- Quick push notifications instead of cumbersome newsletters
- Seamless integration of stores and app
tredy Fashion knew that only with a modern app could the brand remain relevant in the digital world in the long term.
The solution: technology meets user experience
BNO Technology Solutions developed a future-proof architecture for tredy Fashion with a focus on scalability and user-friendliness. The result:
- .NET MAUI: Fast and high-performance app for iOS and Android
- ASP.NET Core WebAPI: Direct connection to the Shopware backend for up-to-date store data
- MongoDB: Flexible, scalable data storage
- WordPress Headless CMS: Easy content maintenance – even without technical knowledge
- .NET Aspire: Containerized microservice environment for maximum flexibility
Push communication: The key to customer loyalty
Push messages are now the most important communication channel – even ahead of email.
According to the Shopgate App Study 2025, event-based pushes (e.g., “back in stock” or shopping cart reminders) achieve open rates of up to 16.9% and conversion rates of 7.5%.
This is exactly where tredy comes in:
👉 With OneSignal as its push partner, tredy can now deliver targeted, personalized messages and reach customers directly.
The result: greater proximity, more sales, a brighter future
With its new app, tredy Fashion has not only implemented a technical relaunch, but also laid the foundation for the following topics:
✅ Digital loyalty cards & loyalty programs
✅ Personalized offers & recommendations
✅ Seamless integration of online and in-store
The bottom line: Not a nice-to-have, but a must-have
Apps are no longer just “another channel” in retail. They are the direct line to the customer – and a strategic basis for sustainable growth.
