Rage Fitness - Custom iOS & Android Mobile App
A React Native mobile app for Rage Fitness, supporting clients between gym sessions on iOS and Android.
Android apps built for scale, performance, and long-term business growth.

Most Android apps fail because they’re built around features, not outcomes. We take a different approach.
At NPK Media, we design and develop Android apps that solve real business challenges, improving customer experience, streamlining internal processes, and creating new revenue opportunities. Our work combines sharp UX, robust engineering, and a strategic mindset shaped by our wider mobile app development expertise.
The result? Fast, reliable Android products people trust — and businesses can scale.
We help organisations across the UK build Android apps that perform flawlessly across devices, screens, and user needs.

High-performance Android apps built in Kotlin or Java for speed, stability, and long-term reliability.
We take care of the full lifecycle, guiding your Android app from concept to launch with growth and longevity in mind.

We clarify your goals, audience, and commercial opportunities, shaping a roadmap that aligns your Android app with your wider digital strategy. This mirrors the approach behind our wider web development services.
Wireframes, prototypes, and user journeys built around clarity, simplicity, and retention. Every screen is designed with intent.
Robust native development using Kotlin and Java, engineered for speed, security, and a smooth user experience across all Android devices.
We validate your app across devices, OS versions, behaviours, and edge cases, ensuring a stable, frustration-free experience at launch.
We handle the full Google Play Store submission process, prepare launch materials, and ensure your app meets all requirements.
After launch, we continue refining your product with feature updates, performance improvements, and long-term technical support.

Effective Android development is about more than code. It relies on clear communication, strong collaboration, and a team truly invested in your success.
What clients value:
We don’t just build Android apps, we build digital products people rely on.
