Mobile application development
Deliver the anytime, anywhere experiences your users expect with intuitive mobile applications powered by a flexible mobile architecture and customised to the unique needs of your organisation.
Accelerate your mobile application development projects
NashTech provides a full range of end-to-end mobile application development services including user interface/user experience (UI/UX) design, development, testing and continuous integration and continuous delivery/deployment (CI/CD).
Working with us, your organisation will be supported by a flexible team of software engineers, senior engineers and other experts, who can offer the right expertise to fit your timeline, budget and wider goals.
We’ll help you to develop secure, compliant and scalable mobile applications by embedding security (OWASP MASVS), accessibility (WCAG), performance optimisation and automated testing (via Appium) into every stage of development.
We’re experts in native platforms such as iOS and Android using Swift, Kotlin, Java and Objective-C, as well as modern cross-platform solutions like React Native, Flutter, .NET MAUI and hybrid/PWA approaches using Ionic, Capacitor, React and Angular.
Our team’s architectural experience spans MVC, MVVM, Modular, and Clean Architecture patterns, while our scalable, modular delivery strategies enable you to deliver super apps. You can also accelerate development time with our advanced AI code assistant, which enhances code quality and provides intelligent suggestions tailored to your project structure and domain.
Solve your mobile application development challenges
It is essential to find the right mobile framework for app development, modernising legacy apps and meeting your business needs. But it is easy to make the wrong choice without the right expertise.
Organisations often struggle to find mobile developers with deep knowledge of native development, strong design capabilities and knowledge of different companies and sectors. This slows projects down, putting them at a competitive disadvantage.
A big challenge is maintaining an in-house mobile development team that can cover all stages of the mobile app development lifecycle – from requirement analysis to development, testing, CI/CD, performance optimisation and security.
Security is a critical non-functional requirement (NFR) for any mobile app. But legacy apps may not have been built with the same level of protection against emerging threats, leading to vulnerabilities.
As new features are added, the risk of breaking existing functionalities increases, which can lead to bugs, poor user experience and delayed releases. Manual regression testing is time-consuming and prone to human error, which makes it difficult to maintain app quality and speed up development cycles.
Benefits of mobile application development with NashTech
Our proven mobile application strategy will give you the tools and expertise you need to modernise your apps, without compromising security or user experience.
We help you to develop new mobile apps and modernise legacy mobile apps by ensuring long-term maintainability, scalability and quicker onboarding of developers. This is critical for dealing with outdated codebases and inconsistent performance. Enabling technologies: Native Android/iOS, React Native, Flutter, .NET MAUI.
We solve the complexity of managing multiple services within a single mobile platform by allowing dynamic loading and integration of micro-apps. This is ideal for enterprises with diverse service offerings. Enabling technologies: Repack.js, React Native, microfrontend approach are used to enable this.
Tackle security and compliance concerns for finance, e-commerce and IoT applications by embedding security best practices from the ground up. This includes secure key management and encrypted communication. Enabling technologies: OWASP MASVS, Secure Enclave, Android Keystore, end-to-end encryption.
Eliminate manual steps in app delivery to reduce time-to-market and errors, while enabling clients to scale mobile delivery with confidence through automated builds, tests and releases. Enabling technologies: Jenkins, GitHub Actions, Fastlane, Bitrise, Firebase App Distribution.
Overcome time-consuming and often inconsistent manual testing by enabling scalable regression test automation. This improves app reliability, saves quality assurance (QA) costs and accelerates feedback loops. Enabling technologies: Appium, BrowserStack, Sauce Labs.
Comply with legal and user inclusivity mandates by designing accessible apps from the start, expanding your reach and reducing the risk of compliance issues down the line. Enabling technologies: WCAG 2.1 guidelines, native accessibility APIs (iOS/Android).

Case study: Leveraging expertise in Bluetooth communication
with a modern, high-performing mobile app
to support future integrations
This telecoms services provider wanted to modernise its Cordova-based app, which was outdated and lacked flexibility for future growth. It needed a technology partner with expertise in Bluetooth communication between mobile devices and hardware, as well as secure key storage. As experts in Bluetooth Low Energy (BLE) applications, NashTech proposed using native development with Swift for iOS and Kotlin for Android. While this would need more effort initially, it meant this client could scale the app with new technologies from Apple and Google.
Case study: Moving beyond technical limitations
for future mobile application development
with core and regulatory SDKs
consistency across platforms
A leading regulated fractional investment platform provider was struggling to integrate a native KYC SDK into its legacy cross-platform app. Its architecture also lacked flexibility to support native SDKs, which created roadblocks in meeting compliance and user onboarding standards. NashTech provided a modern solution – Flutter, a cross-platform framework – known for its performance and native interoperability. The team also developed a proof of concept (POC) enabling its SDK to be fully integrated, as well supporting faster adaptation of new features like social investing entitlement management and real-time asset tracking.
