Discover the power of swift app development and how companies across industries are leveraging Kotlin to revolutionize their mobile strategies. From building cross-platform applications with shared logic and UI to developing reliable, high-performance backends — explore real-world strategies, integration approaches, and the benefits teams gain from using Kotlin in production.
"One exciting trend for Duolingo is that the more we use Kotlin Multiplatform internally, the more we find ourselves speeding up in terms of shipping. It turns out after you learn something, you get really good at it. Now there's a lot more confidence behind it and we're building up that knowledge," says John Rodriguez, Client Platform Team.
Unifying Codebases
Google Docs' experiment with Kotlin Multiplatform proved a resounding success. "We consider the experiment validated in our Google Docs experiment... We're actually very happy with it," shares Jason Parachoniak, Multiplatform Lead in Google Workspace.
Boosting Performance
McDonald's app saw significant improvements after adopting Kotlin Multiplatform. "After a successful initial test with the payments feature, we expanded KMP to our entire McDonald's application. With KMP, we saw fewer crashes and better performance across both platforms after the launch," explains Varsha Singh, Project Manager at Umain.
Simplifying Development
X's experience with Kotlin Multiplatform resulted in a "huge speed win" for the team. "Starting from this small of a team, it was a huge speed win for X to be able to use KMP and write all of that logic once in one place... When you write a bug—not that I ever do that—you only have to fix it in one place," says Eric Denman, Software Engineer at X.
Powering Cross-Platform Development
Perk's mobile apps now enjoy unified tooling and design across Android and iOS thanks to Kotlin Multiplatform. "We started with a small shared UI component, but have since migrated our design system to CMP and used it to develop larger CMP features," shares the Perk team.
Realizing the Benefits
Philips consolidated business logic into shared code, reducing deployment time and errors. Jeroen Brosens, Software Architect at Philips, notes, "We can now develop once and deploy more. Before KMP adoption, we had an often heard saying, it works differently on iOS, but it has been a while since we heard that one."
Driving Efficiency
Autodesk uses Kotlin Multiplatform to unify offline synchronization logic and data models across iOS, Android, and Windows platforms. This shared codebase simplifies development, enabling feature reuse across platforms and improving collaboration.
Scaling Mobile Development
OpenSooq leverages Kotlin Multiplatform to scale mobile development efficiently, shipping faster and sustaining a crash-free stability rate of over 99.7%.
Unlocking Innovation
Instabee's Android Developer, Johannes Svensson, praises the simplicity of Compose Multiplatform: "Compose Multiplatform really simplified adding support for iOS. The level of shared code, without adding complexity, is staggering. It really streamlines app development and enables us to innovate and iterate at an insane speed."
Streamlining Development
Quizlet's global learning platform boasts a combined 100 million active installs, thanks in part to Kotlin Multiplatform. "By transitioning our shared code from JavaScript to Kotlin, we significantly improved the performance of both our Android and iOS applications," shares Quizlet.
Empowering Innovation
Worldline's Eroski app saw a seamless transition to Kotlin Multiplatform, resulting in a high-quality app with over 99% crash-free users among 800,000 active users.
