Cutting-Edge iOS Experiences

Our iOS App Development Services

Bespoke iOS Development

Our robust iOS app development process helps businesses leverage the power and security of Apple's operating system without compromising native performance, UX or quality. We have extensive experience building commercial applications in iOS, having worked with clients such as the NHS, Trainline and YourParkingSpace.

iOS Consultancy

From long-term support to urgent project recovery, we can offer iOS consultancy services to complement your existing team and platform. Alongside developing and maintaining iOS applications, our iOS app developers are able to provide iOS audits on platforms of any scale to help you to understand any improvements or further development required.

iOS Project Rescue

Many of our clients come to us with existing iOS apps that require urgent support. If your iPhone app has run into difficulties or you’ve fallen out with your existing iOS app developer, we can quickly get you back on track with full code audits and a comprehensive recovery plan.

Enterprise iOS Development

Our iOS app development team can support you at every stage of the development process, from mapping out technical architecture and integrations to developing user research and feature mapping. We can also help you maintain and further improve an existing iOS application, tracking new feature updates against core business KPIs.

We Deliver

The Complete iOS Development Package

Stunning UI/UX Design

Our iOS developers make the most of Xcode, Apple’s integrated development environment that allows them to test and refine all aspects of design, including display sizes and device orientation. We work across the full suite of Apple devices, including iPad, Apple Watch and Apple TV.

Lightning-fast Performance

Native apps for iOS are able to fully utilize the power of the device’s CPU, which makes them exceptionally fast and performant. By tapping into the full range of iOS features we create engaging iPhone apps that can leverage innovative technologies like AR, Apple Pay and Voice Control.

Optimise and Grow

Alongside designing, building and maintaining iOS apps, our iPhone app development team can also help with App Store Optimisation and driving growth. We work with many of our clients on an on-going Agile basis, to continually improve their apps, develop their product backlog and release new features.

Our iOS Development Process

Foundation Sprint

Our comprehensive Discovery process turns business objectives, user profiles, and commercial models into functional specifications and prototypes. We use this information to define success metrics and target users, alongside guiding both technical and product decisions. This ensures your iOS app is built on solid foundations.

Solution Sprint

The Solution Sprint is where we work out the details of the product: What does it look like, how does it make your users’ lives easier, and who are the stakeholders that should be involved in working on this solution. Once we have mapped out your users, their problems and the high-level concept for your product, we will use this sprint to build process maps, clickable wireframes and refine your product backlog.

Delivery Sprint

Building products users love is an iterative process. Delivery is where we move onto the ongoing delivery of the product, working in 2-week sprints to deliver against the agreed initial priority items within the backlog. Following dual-track Agile principles, the product team will continue to refine the product and backlog as the delivery of the solution begins. This allows us to consistently incorporate user and stakeholder feedback to continuously evolve your product for the better.

Deployment Sprint

Stable. Seamless. Secure. These three things are essential when it comes to deploying software and applications. The Deployment Sprint is where we coordinate a release across several teams and systems and ensure that it is successful. The goal of the deployment sprint is to ensure that we can run the correct processes across development, staging and production environments with an agreed handover process. This ensures that we’re deploying secure code and have a tightly controlled rollout.
