In a tech-driven world where mobile applications are dominant, OneApp embarked on a revolutionary journey that would change the very fabric of app development.

Faced with the persistent dilemma of choosing between the performance of native apps and the convenience of cross-platform solutions, OneApp dared to challenge this binary choice. Our quest was to deliver a user experience that went beyond boundaries.

While we have tried many different platforms like KMM, React, etc. We compared them and tested all the things, and abide by the following principle:

  1. Question Everything: Even though many people say React is a preferred platform for hybrid apps, we questioned it, and tested on our own.
  2. Test ideas by the evidence gained from observation and experiment. If a favorite idea fails a well-designed test, it’s wrong. Get over it.

Guided by these considerations, we started on our journey, exploring every avenue, and ultimately, it became crystal clear that Flutter was the optimal choice for our mission. Our rigorous testing and comprehensive Proof of Concepts (PoC) involving various prominent hybrid technologies led us to this conclusion.

Nevertheless, our path to victory was not without its share of imposing technical hurdles. Here we share the challenges we overcame during this journey.

Bridge Compatibility: Integrating Flutter with native code was extremely tough. The product’s hybrid nature meant that every connection point had to be meticulously managed. Compatibility became our guiding star.

UI Consistency: Crafting a consistent user interface that would seamlessly straddle both iOS and Android. Flutter’sUI flexibility excited us but comes with challenges when integrating with Native technologies, and OneApp was determined to ensure that the user experience remained visually harmonious.

Performance Optimization: We refused to rest until our product ran with the precision and efficiency demanded by modern users. Every microsecond counted, and we fine-tuned to ensure it offered the smooth, responsive performance that users want.

Plugin Prowess: In a concentrated market of Flutter’s plugin ecosystem, OneApp took on the task to carefully choose their own plugins to ensuring seamless integration with our native code. This was the hallmark of OneApp’s expertise.

Asset Management: Handling assets such as images, fonts, and resources required meticulous configuration. We need to make sure that our app security is not compromised anywhere. We developed a robust asset management system that allowed us to create an effortless inclusion and usage of these assets in our hybrid app.

Synchronization: Maintaining synchronization between Flutter updates and native iOS releases was a challenge. We adopted a well-defined versioning and testing strategy to ensure that new releases did not disrupt the user experience.

Despite many such challenges, we introduced our first hybrid app — a symbol of innovation in app development.

Innovation at Its Peak: The Success of Our Magenta Moments Program

Magenta Moments is Telekom EU initiative to reward our customers with coupons and other kind of perks, to increase the engagement of users in our self care app. From the begining we know that this is going to be a very huge project, still we want to tickle our tech side and we decided that this will be the first ever program in DT’s history that will utilize this hybrid tech.

Starting this exciting journey, where we incorporated Flutter into our iOS and Android app, we explore the success of the Magenta Moments Program. As part of the OneApp ecosystem, it symbolizes our dedication to outstanding user experiences and proves our relentless pursuit of excellence.

Magenta Moments Glimpse

We’ve faced and embraced new challenges in our journey, always working hard to make things better. Every problem we faced was solved with creative ideas and strong commitment, leading to a big success that has made a lasting impact in the digital world. The Magenta Moments Program’s success doesn’t mean we’re done; instead, it marks the beginning of a new and exciting part of our story.

Our goal is clear: to provide amazing experiences for users. This program has quickly gained popularity worldwide, being active in four countries with hundreds of thousands of enthusiastic users in just a few months. The Magenta Moments Program is a big hit, drawing in users and boosting our revenue per session (RPS) rapidly. It’s a phenomenon that users love, and it’s greatly improving how well we’re doing.

As we go on this exciting journey, our focus on innovation and excellence remains strong. It guides us through the ever-changing world of digital innovation.

In our upcoming blogs, we’ll show you how to transform your approach to app development. We’ll teach you how to improve the user experience, make your code easier to maintain, and speed up the time it takes to get your app to market.

Throughout this series, we’ll get into the technical details of creating hybrid apps and demonstrate how to smoothly add them to your own applications.

Stay Tuned!
