iOS App Development Services iPhone apps that feel made by Apple.

Our iOS app development services cover discovery, iPhone and iPad UI/UX design to Apple's guidelines, native development in Swift and SwiftUI, backend APIs and an admin panel, payments and in-app purchases, TestFlight beta testing, App Store submission and ongoing updates for new iOS versions. We can also take over and modernise an existing iPhone app.

The cost of iPhone app development depends on the number of screens and user roles, payment and subscription needs, integrations, iPad or Apple Watch support and the admin panel. We give you a fixed, itemised quote after a short discovery call, so you see the cost of each feature and can phase the scope. Apple's developer programme fee is paid directly by you to Apple.

A focused iPhone app with an admin panel usually takes 8 to 14 weeks from scoping to App Store approval. Apple's review itself typically takes a day or two, though first submissions can take longer. You receive TestFlight builds every week during development, so you can check progress on your own device.

You don't need a Mac — we build on our own. You do need an Apple Developer Program membership in your own or your company's name, because that is the account the app is published under. We guide you through enrolment, including the D-U-N-S number required for organisations, and set up App Store Connect for you.

Native Swift gives the best performance, the most iOS-like feel and immediate access to new Apple features such as widgets and Live Activities. Flutter or React Native are better value when you need Android and iOS from one codebase. For apps aimed mainly at iPhone users, or with heavy device integration, we recommend native iOS app development.

Common reasons are crashes or incomplete features, missing in-app account deletion, privacy answers that don't match the app, selling digital content outside in-app purchase, unclear metadata and missing demo login details for the reviewer. We run a pre-submission checklist against Apple's guidelines and handle any feedback until the app is approved.

Yes. We design adaptive layouts so the same app works properly on iPad with Split View, keyboard shortcuts and Apple Pencil where useful. We can also add home-screen widgets, Live Activities and an Apple Watch companion app for quick actions and notifications.

You do. The app is published under your Apple developer account, and the Swift source code, Xcode project, designs and certificates are handed over to you. We keep code in a repository you control, so you can continue with us, your own team or another vendor in future.

Yes. Apple releases a major iOS version every year. Our maintenance plans include testing against the beta, fixing compatibility issues before release day, updating to new SDK requirements, crash monitoring and a set amount of feature work each month, with response times agreed in writing.
