Mobile App Development
Mobile apps for iOS and Android, built to last
A great mobile app feels effortless and never lets your users down. At Xium Labs we design and engineer native and cross-platform apps for iOS and Android: fast, reliable and secure, with the backends and APIs that power them built under the same roof. We handle the whole journey, from first concept to a polished release on the App Store and Google Play, and you own every line of the code.
Part of our product development practice.
What is mobile app development?
It is the design and engineering of software that runs on phones and tablets, along with the services behind it. We build native apps for maximum performance and cross-platform apps for reach and speed to market, connect them to secure backends and APIs, and take them all the way through testing, store submission and launch.

App Store Launch
Submission, review and release on the App Store and Google Play.
How We Build Mobile Apps
Every mobile build follows a clear, transparent path, so you always know what is happening and why:
- Discovery: A free scoping call and a costed plan. We map the users, the platforms and features in scope and whether the numbers justify building.
- Design: UX, architecture and a clear technical approach agreed before a line of code is written.
- Build: Short, visible cycles with working software delivered early and often.
- Launch: Production deployment with monitoring, documentation and a full handover. You own the code.
- Secure: Penetration testing and hardening, so what you launched holds up against real-world attack.
Mobile App Development FAQs
Native or cross-platform: which should we choose?
It depends on your product. Native suits performance-critical or hardware-heavy apps; cross-platform is faster and more economical when you want iOS and Android from one codebase. We advise on the best fit during scoping.
Do you handle App Store and Google Play submission?
Yes. We manage store submission, review and release, and can publish under your accounts so you keep full control.
Do you build the backend too?
Yes. The APIs, databases and cloud that power your app are built and secured alongside it.
Do we own the code?
Yes, completely, including the backend. Clean, documented and yours.
How do you keep mobile apps secure?
We use encrypted storage, safe data handling and hardened APIs, and the same team pen-tests the app and its backend.
How long does a mobile app take?
A focused first release is typically a few weeks to a couple of months depending on scope. We agree a timeline after a free scoping call.
