How We Work

Our iOS app development process

ERS uses a structured but flexible approach that keeps you involved at every stage, from early prototypes to
the final App Store release and beyond.

1 Discover

Requirements & vision

We clarify the purpose of the app, who will use it, which platforms (iPhone, iPad, Apple Watch, etc.) are required and what success looks like.

2 Design

UX/UI & prototyping

Wireframes and interactive prototypes show key journeys and screens, so you can validate the experience before development begins.

3 Develop

iOS build

Our developers build the app using Swift, implement integrations, and ensure performance and security are built into the core.

4 Test

Testing & refinement

We test across devices and scenarios, refine based on feedback and prepare the app for TestFlight and final release.

5 Launch

App Store release

ERS assists with App Store submission, compliance checks, metadata and rollout strategy so your launch runs smoothly.

6 Evolve

Ongoing improvements

After launch, we support new features, platform updates and performance tuning based on analytics and real-world use.

FAQs

iOS development questions we’re often asked

How long does it take to build an iOS app?

Timelines vary based on scope and integrations. A simple app might take 6–10 weeks, while more complex or integrated solutions are usually delivered in phased projects over several months. We’ll provide a realistic plan based on your requirements.

Can you build separate versions for iPhone and iPad?

Yes. We can design layouts and interactions optimised for both iPhone and iPad, ensuring each device type gets the best possible experience.

Do you develop for Apple Watch or Apple TV?

We can extend solutions to watchOS or tvOS where it makes sense—for example, to provide quick-glance notifications or dashboard-style experiences.

Can the app integrate with our existing systems?

Yes. Integration is one of ERS’s core strengths. We frequently connect iOS apps to existing ERPs, CRMs, databases, APIs and bespoke systems, ensuring data flows securely and reliably.
