iOS App 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.
