Mobile App Development
Apps your users will love, built for scale.
We build high-performance mobile applications for iOS, Android, and cross-platform using Flutter and React Native. Our mobile apps are designed for speed, reliability, and exceptional user experience - helping you engage customers wherever they are.
Our mobile development process starts with user research and UX design, ensuring we build apps that people actually want to use. We then develop, test rigorously on real devices, and deploy to app stores - handling the entire submission and review process.
Post-launch, we provide ongoing maintenance, performance monitoring, crash analytics, and iterative feature development. Our apps are built with security best practices, including encrypted data storage, certificate pinning, and secure API communication.
How Mobile Apps Works in Practice
A mobile app is judged in the first thirty seconds after install: does it open fast, does it feel native, does it ask for only the permissions it needs, and does it work when the network is poor. Getting those right is a matter of platform experience, and getting them right across iOS and Android on one budget is a matter of choosing the right approach.
We build cross-platform apps with Flutter and React Native when one codebase serves both platforms well, and native apps in Swift and Kotlin when the app leans on platform features such as hardware access, background processing or heavy graphics. In every case the backend, authentication, push notifications, analytics and crash reporting are part of the delivery.
Security is built in from the first sprint: secure storage, certificate pinning, obfuscation, secure authentication flows and a mobile penetration test before release. For regulated industries we align with OWASP MASVS and the store review requirements so submission is not a surprise.
Our Mobile Apps Process
Every engagement follows the same six steps, scoped to your size and your goals, so you always know what happens next and what you will receive.
- 01
Product discovery
We define users, core journeys, platform strategy and the smallest release that proves value, and produce a prioritised backlog with estimates.
- 02
UX and UI design
Wireframes and high-fidelity designs that follow iOS Human Interface Guidelines and Material Design, reviewed with real users where possible.
- 03
Architecture and backend
API design, authentication, data model, offline strategy and third-party integrations, built to scale beyond the first release.
- 04
Iterative development
Two-week sprints with a testable build at the end of each, automated tests and CI/CD that produces signed builds for TestFlight and Play internal testing.
- 05
Quality and security
Device matrix testing, performance profiling, accessibility checks and a mobile penetration test against OWASP MASVS.
- 06
Release and growth
App Store and Play Store submission, release notes, monitoring, and an optional retainer for updates, OS changes and new features.

Mobile Apps Questions, Answered
Flutter, React Native or native?
Flutter and React Native cover most business apps with one codebase and near-native performance. Native Swift and Kotlin are worth the extra cost when the app depends on advanced hardware, AR, complex animations or the tightest platform integration. We recommend after discovery, not before.
How long does it take to build an app?
A focused MVP typically takes three to four months from discovery to store release. Apps with complex backends, payments or regulatory requirements take longer, and we phase them so you can launch early.
Do you handle App Store and Play Store submission?
Yes, including store listings, screenshots, privacy declarations, review responses and the compliance details that commonly cause rejections.
Who owns the code?
You do. Code lives in your repository from day one and all accounts, certificates and keys are registered to your organisation.
Can you take over an existing app?
Yes. We start with a code and security audit, stabilise the release process, then plan improvements. We have inherited apps in both Flutter and native codebases.
What about ongoing maintenance?
iOS and Android ship major updates every year and libraries change constantly. A maintenance retainer covers OS compatibility, dependency updates, monitoring and small enhancements so the app never falls behind.
