Native apps for iPhone and iPad.

We build iPhone and iPad apps in Swift and SwiftUI that follow Apple's guidelines, use the features people already rely on and are ready for App Review.

  • Feels native on iPhone
  • Works on iPad too
  • Ready for App Review

Your iOS build

Design

Liquid Glass ready

Beta testing

Through TestFlight

Many iPhone apps feel like websites in a wrapper, so they look out of place and lose people quickly. We build with Apple's own frameworks and patterns, so your app looks, moves and behaves like it belongs on iPhone.

The iPhone features that matter.

We pick the Apple features that serve your users, then build each one to Apple's standards and test it on real devices.

SwiftUI interfaces

Screens built in SwiftUI with Apple's standard navigation, tab bars and sheets, adopting Liquid Glass so your app matches the current look of iOS.

Widgets and Live Activities

Home Screen and Lock Screen widgets keep key information a glance away. Live Activities show progress, like an order or a session, on the Lock Screen and Dynamic Island.

Sign in with Apple

Fast, private sign in with Face ID, plus passkeys where they suit your app. We add account deletion inside the app, as Apple requires.

Apple Pay and StoreKit

Apple Pay for physical goods and services, and StoreKit for digital content and subscriptions, so every purchase follows Apple's payment rules.

Notifications and Siri

Push notifications people can control, plus App Intents so key actions work from Siri, Shortcuts and Spotlight.

Accessibility built in

Support for Dynamic Type, VoiceOver and Dark Mode from the first screen, so the app works for everyone who downloads it.

Done properly.

The details that decide whether iOS apps pays off.

Choosing Swift or React Native.

Swift and SwiftUI suit apps that lean on Apple features such as HealthKit, widgets or Apple Watch. If you also need Android, React Native with Expo shares one codebase. We recommend a route after the first call.

Checked against Apple's review guidelines.

Before submission we check your build against the App Review Guidelines, covering privacy details, account deletion, payments and sign in. Beta testers try the app through TestFlight first, so issues are fixed before Apple sees it.

How it works.

Clear steps, and you approve each one before we move on.

  1. 01

    Plan

    We agree the core features, devices and Apple capabilities your first version needs.

  2. 02

    Design

    We design every screen to Apple's guidelines and test a prototype on your iPhone.

  3. 03

    Build

    We build in Swift or React Native and share TestFlight builds as we go.

  4. 04

    Release

    We submit to the App Store, handle review and plan the next update with you.

Example project

A boutique gym that wants members booking on iPhone

Members book classes through a mobile website that logs them out and forgets their details. The owner wants a proper iPhone app with reminders, a membership pass in Apple Wallet and quick rebooking.

What we would do

  • Map booking, rebooking and cancellation flows
  • Design SwiftUI screens to Apple's guidelines
  • Add Wallet passes and class reminders
  • Beta test with members through TestFlight

An illustration of how we would approach it, not a client result.

What you would get

  • A native iPhone app in Swift
  • Apple Wallet membership passes
  • Class reminders members can control
  • App Store listing and submission

Questions, answered.

Do you build iOS apps in Swift or React Native?

Both. We use Swift and SwiftUI when your app relies heavily on Apple features, and React Native with Expo when you want iPhone and Android from one codebase. We recommend one after hearing your plans.

Will my app work on iPad as well?

It can. We design layouts that adapt to iPad screens, multitasking and keyboard use, or keep the app iPhone only if that suits your users better. We agree this during planning.

What happens if Apple rejects the app?

We read the reviewer's notes, fix the issue or send Apple the clarification it needs, and resubmit through App Store Connect. We check the App Review Guidelines before every submission to avoid common rejections.

How much does an iOS app cost?

Every iOS app is quoted after a short call, with a fixed price agreed before we start. Updates and support after launch are covered by a fixed monthly fee.
