Our app development services

Native app development

Native app development

Traditional native apps are developed for each device platform (iOS and Android) and are coded to use the technology of the device (phone or tablet). Native mobile apps can make full use of device features - not only the hardware but potentially also stored data and contacts - and our full-stack team are experts at developing technology solutions to make your native app a complete success.


iOS and Android apps

Our design and development team create apps for both Android and iOS, and our services include submission into the App Store and Google Play Store, to ensure that your new app can be discovered by your target audience. For businesses creating apps for internal purposes, they can also be installed directly to team members' Android devices without going through the Play Store.

As top app developers, one of our main focuses has been creating non-commercial apps that enhance business processes, and we have a wealth of experience in working within the facilities management, healthcare, education and legal professions.

Progressive web app development

Progressive web app development

Progressive web apps (PWA) combine the user experience of an app with the accessibility of a website. We think they're the future.

Running your applications within a mobile web browser instead of a traditional installed native app makes sense for many clients. This is where progressive web apps can thrive - the development time is quicker, costs are reduced and they're gaining more features in each browser release.

Progressive web app development

Some of the main benefits of PWAs include:

  • Improved performance
  • Faster loading times
  • Engaging user experiences
  • Reduced data use

They're accessible from any device and can generally be much more cost-effective than a native app. Progressive web apps are by their very nature mobile-first, but they also accessible via a desktop, which presents much more scope than traditional native apps, giving great user experience regardless of device.

Bespoke web app development

Bespoke web app development

Our apps are coded using the latest development techniques to make the most of reduced screen size, ensuring users don't get lost within your site and can intuitively navigate your key information. Plus, our PWA development is always properly planned within the UX design process to ensure that the mobile experience meets expectations for usability.

Website development capability is evolving faster than ever, alongside mobile internet usage, and we believe that progressive web apps are the future for all website development in the coming years. We're developing more and more PWAs for businesses whose device traffic is heavily skewed towards mobile and tablet. Have you thought about a progressive web app for your next project?

Our mobile app development process

Consultation & objectives

The first step in the mobile app development process is sitting down with you to fully understand what you want to achieve. During this stage of the application development project, our app design agency experts liaise with you to identify your target users, the purpose of the app, research the competition and establish the aims and objectives of your business.

Wireframe & refine

Our apps always have UX at heart, that's why we spend time ensuring that the user experience is smooth and effective to achieve your goals. Once the purpose is decided, our application development UX team will get to work on the wireframe to provide a visual structure of the app's functionality.

App build

The core app build will then start, beginning with the back-end development to support the desired functions of your app, followed by integration with any APIs or third-party systems. The next stage is to develop the front-end for your native or progressive web app and make the user interface work intuitively for the user.

Analytics & UX optimisation

As a data-driven mobile app development company, we know just how important it is to know exactly how your investment in digital products is working for you. So your project manager will take an in-depth look into the analytics of your new app and look to understand and optimise the user experience.
