CUSTOM IOS APP DEVELOPMENT

At Ronins, we build iOS apps that do more than look good, they solve real commercial problems. Whether you’re a scale-up founder chasing growth, a CMO under pressure to deliver better mobile engagement, or an enterprise leader rolling out a digital first strategy, our iOS app development team partners with you to deliver meaningful results. With offices in London and Guildford, Surrey, we work across the UK and globally, always grounded in the realities of business, not buzzwords.

From MVPs and investor ready prototypes to complex, enterprise grade apps, we design and develop iOS applications that blend intuitive UX with sharp technical execution. No bloated teams. No vague deliverables. Just experienced iOS app developers focused on moving your business forward.

Lets Talk

OUR APP DEVELOPMENT SERVICES

What success looks like

An iOS app that users actually use. It loads fast, feels native, and delivers results you can measure, growth, retention, revenue. We define success around your goals, whether that’s increasing in app conversions, reducing support tickets, or turning more free users into paying ones.

From scale-up MVPs to enterprise rollouts, every iOS app we build is designed to deliver business value, not just ship features.

Problems we solve

You’ve launched before, but the app underperformed. It crashed under load, users didn’t come back, or the UX felt disconnected from what they actually needed. Maybe it was never properly aligned with your backend or business goals.

We fix that. Whether it’s poor retention, slow dev cycles, or product–market fit issues, our iOS app development team focuses on the root cause, not just the symptoms.

We optimise

Shipping is the start, not the end. We track real user behaviour, analyse drop-off points, and optimise your iOS app over time. That might mean improving onboarding flows, refining performance, or rolling out new features based on actual demand.

As your product evolves, we scale with you, keeping the experience sharp, the code clean, and your users engaged.

FAQs

Questions we are asked before we are hired

What makes your iOS services different?

Our mobile app development services are built on a foundation of strategic planning and technical excellence. We assign a dedicated project manager to every client, ensuring clear communication throughout the development lifecycle.

Our proven track record includes delivering complex projects for diverse industries, with a focus on understanding your target audience before writing a single line of code. This approach creates applications that genuinely connect with Apple users while addressing your specific business challenges.

How do you ensure the budget and timeline?

We maintain budget and timeline integrity through detailed project scope documentation and transparent milestone tracking. Our team of iOS developers follows a structured development process that identifies potential challenges early.

By conducting thorough planning sessions upfront and incorporating regular client feedback loops, we minimise costly mid-project changes. This seamless process helps us deliver on time while maintaining the quality standards required for native iOS apps.

What experience do your developers have?

Our iOS app developers bring specialised experience across healthcare, finance, retail, education, and enterprise sectors. Each dedicated iOS developer on our team has at least five years of commercial development experience, with many having built apps that serve millions of users daily.

This diverse background allows us to understand industry-specific challenges and regulations, ensuring your iOS application development meets both technical requirements and business objectives from day one.

How do you approach UX design?

Our UX design process begins with comprehensive user research and persona development to understand your target audience deeply. We create interactive prototypes that allow for testing user interaction patterns before development begins.

This human-centered approach ensures we create intuitive interfaces that feel natural to Apple users while maximising engagement. By focusing on Apple’s design principles, we create experiences that feel native while still reflecting your brand identity.

What iOS technologies do you use?

We maintain expertise across the full spectrum of iOS technologies, including Swift, SwiftUI, Core Data, ARKit, Core ML, HealthKit, and CloudKit. Our phone developers stay current with Apple’s ecosystem updates, ensuring we leverage the latest capabilities in mobile technology.

This technical depth allows us to recommend the right tools for your specific needs, whether you’re building a simple consumer app or complex enterprise mobile solutions that integrate with existing systems. We also use technologies like react native and flutter for hybrid app development.

How do you handle iOS app testing?

Our iOS app testing methodology combines automated and manual approaches across multiple device configurations. We implement unit testing, UI testing, performance testing, and security scanning throughout the development cycle, not just at the end.

This continuous quality assurance identifies issues early when they’re less expensive to fix. Our testing team verifies compatibility across different iOS versions and devices, ensuring consistent performance regardless of your users’ hardware.

What ongoing support do you provide?

Our support services extend well beyond the initial launch, ensuring your app remains updated and performs optimally as iOS evolves. We offer tiered support packages including monitoring, performance optimisation, bug fixes, and feature enhancements.

Many clients maintain long-term relationships with us as their mobile application development partner, allowing them to focus on their core business while we manage the technical aspects of maintaining a successful mobile presence.

How do you determine the cost of an iOS app?

The cost of developing iOS apps depends primarily on your app’s complexity, feature set, integration requirements, and timeline.

Rather than offering one-size-fits-all pricing, we provide detailed estimates based on a thorough requirements analysis. Our transparent pricing model breaks down costs by feature, allowing you to prioritize elements based on budget constraints. This approach ensures you understand exactly what drives the investment required for your iOS app project.

Can you work with our internal team?

We excel at collaborative development, whether supplementing your internal resources or providing dedicated iOS developers to lead specific initiatives. Our team adapts to your preferred communication tools and development methodologies, creating a seamless integration with your existing processes.

This flexibility allows us to function as either your complete mobile solutions provider or as specialised support for your in-house development team, depending on your specific needs.

What is your typical process?

Our iOS app development process follows a proven six-stage methodology: discovery and planning, UX/UI design, development sprints, quality assurance, deployment, and post-launch support. Each phase includes client checkpoints and approval gates to ensure alignment. This structured approach balances efficiency with flexibility, allowing us to adapt to changing requirements while maintaining progress toward your launch goals for both simple and complex projects.

How do you approach security?

Security is integrated throughout our development workflow, not added as an afterthought. We implement Apple’s latest security frameworks, use secure coding practices, and conduct regular vulnerability assessments as part of our iOS application development standards.

For applications handling sensitive data, we implement additional measures like certificate pinning, secure local storage, and biometric authentication. This comprehensive approach protects both your users’ data and your business reputation.

What makes a successful iOS app?

Successful iOS apps combine technical excellence with genuine user value and business alignment. The most effective applications address specific pain points for your target audience while delivering an intuitive experience that respects Apple users’ expectations.

Strategic planning before development ensures your investment addresses real market opportunities. By focusing on core functionality first and gathering user feedback early, we help you build apps that achieve your business objectives while delighting users.

Ronins have been integral to our company’s digital strategy — from defining requirements through to successful implementation. Their detailed subject knowledge and delivery expertise have made the process fit seamlessly with our current systems and helped to drive our business forward.
