iOS APPS
that feel native.

We build iOS apps in Swift and SwiftUI that look and feel the way iPhone users expect — fast, smooth, and free of the small annoyances that make people delete an app by day two. Consumer apps, enterprise tools, watchOS, tvOS — built to Apple's standards.

Everything Apple,
covered.

From iPhone to iPad to Apple Watch and tvOS — and the App Store submission process from end to end.

Native
iPhone

iPhone Apps

Native iPhone apps built in Swift and SwiftUI. We design for one-handed use, dark mode, dynamic type, and all the small things iPhone users notice without quite knowing why. Consumer app, SaaS companion, or internal tool — fast, stable, and built to pass App Store review on the first try.

Native
iPad

iPad Apps

If your app is going to live on iPad, it deserves more than a stretched-out iPhone layout. We build proper iPad experiences with split view, multitasking, Apple Pencil support, and keyboard shortcuts where they make sense — great for enterprise dashboards, productivity tools, and content-heavy apps.

Wearable
watchOS

Apple Watch Apps

Apple Watch is not a tiny iPhone. The best watchOS apps surface one piece of useful information at exactly the right moment, then get out of the way. We build watch apps for fitness, health tracking, alerts, and quick-action workflows — designed for the glance-and-go reality of wearables.

Ten-foot UI
tvOS

Apple TV Apps (tvOS)

We build tvOS apps for content streaming, digital signage, and enterprise presentation use cases. Designed around the remote, the couch, and the ten-foot interface — not just ported from another platform.

End to end
Submission

App Store Submission

The App Store review process is its own little discipline. We handle the metadata, screenshots, privacy disclosures, content ratings, and back-and-forth with the review team. If Apple comes back with a question, we deal with it. You do not have to learn the rejection codes.

The Technology Choice

The language Apple
actually wants you to use.

The iOS APIs that ship first, the Xcode tooling that gets the most love, the documentation that's most current — all of it points at Swift and SwiftUI. That matters more than it sounds.

Nice to write, safe to ship

Swift is type-safe and fast, and it eliminates entire categories of bugs that used to be common in Objective-C.

One codebase, every screen

SwiftUI builds adaptive layouts across iPhone, iPad, Watch, and Mac — fewer surprises when iOS 19 or 20 lands.

UIKit when it's the right call

We still reach for UIKit when maintaining an older app or covering a corner SwiftUI doesn't reach yet. For anything new, Swift and SwiftUI is the right call.

Our iOS Process

From idea to
App Store.

App Store guidelines are not the place to discover constraints in month three. We surface them in week one, then build in two-week sprints you can actually click through.

STEP 01

Get the brief right.

We figure out who the app is for, what problem it actually solves, and which Apple platform rules will shape the build. App Store guidelines surface in week one, not month three.

What you walk away with
  • Users & job-to-be-done defined
  • Platform rules mapped early
  • A scope you can budget around

STEP 02

Follow the instincts.

Before any pixels, we map how users move through the app. iOS users have strong instincts about how iPhone apps should work, so we follow those where they help and break them only when we have a real reason.

What you walk away with
  • Every flow mapped & validated
  • Clickable wireframe prototype
  • Sign-off before visual design

STEP 03

Design with the HIG.

We design within Apple's Human Interface Guidelines, not against them. Typography, spacing, motion, accessibility, dark mode, dynamic type — all of it gets attention. iOS users notice when an app feels native.

What you walk away with
  • HIG-aligned design system
  • Dark mode & dynamic type
  • Accessibility-audited components

STEP 04

Swift, in two-week sprints.

We write in Swift and SwiftUI, work in two-week sprints, and keep the codebase modular and version-controlled. You'll see working builds along the way — not a big reveal at the end.

What you walk away with
  • Working build every 2 weeks
  • Modular, version-controlled code
  • Full visibility in your tools

STEP 05

Real devices. Real edge cases.

We test on real iPhone and iPad models, current iOS versions, and a few older ones your users probably still have. Performance, edge cases, accessibility, and App Store technical requirements — all before submission.

What you walk away with
  • Real-device QA matrix
  • Accessibility & performance audited
  • Review-ready before submission

Through to approved.

We prep the submission and send it in. Standard apps usually clear in 24–48 hours; in-app purchases or sensitive APIs like health or location can take 3–7 days. We handle reviewer questions and get the app approved.

Cross-Platform Option

Need both stores,
fast?

If you need iOS and Android and the budget or timeline is tight, native Swift might not be the right starting point. React Native and Flutter let us build for both platforms from one codebase, which cuts cost and time significantly.

There are trade-offs — mainly around the deepest hardware integrations and certain animation-heavy use cases — but for most apps cross-platform holds up well. We'll tell you honestly which approach fits your project. Sometimes native is worth it. Sometimes it's overkill.

Frequently Asked Questions

iOS questions we
get often.

It depends on what you're building — number of screens, backend complexity, third-party integrations, and whether you need iPhone-only or a universal iPhone and iPad build all move the number. A focused consumer or utility app usually starts on the lower end; a full-featured product with custom backend and integrations sits much higher. We scope properly after a discovery call and give you a real number, not a random range.

Apple's review is usually 24 to 48 hours for standard submissions. First-time submissions, apps with in-app purchases, or apps using sensitive APIs like health, location, or camera can take 3 to 7 days. We prep the submission to be review-ready on the first try and handle reviewer follow-ups quickly so you don't lose a week to back-and-forth.

Yes. We build universal iOS apps that adapt cleanly between iPhone and iPad, or iPad-specific apps when the larger screen calls for a distinct layout. SwiftUI's adaptive layout system handles most of the work, and we test on real devices to make sure nothing breaks at the edges.

Yes, and it's one of the more common projects we take on. Older iOS apps accumulate deprecated APIs, broken layouts on newer devices, and rejections that didn't apply two years ago. We audit the codebase, scope the work, and modernise it without a full rewrite where possible. Sometimes a UIKit-to-SwiftUI migration makes sense, sometimes it doesn't — and we'll tell you which.

Native iOS in Swift gives you the best performance, the deepest Apple integration, and the cleanest iOS feel. Cross-platform using React Native or Flutter gets you to iOS and Android together from one codebase — faster and cheaper, with minor trade-offs on platform-specific features. If your app is iOS-first or relies heavily on Apple hardware, native is usually worth it. If you need both platforms quickly, cross-platform is the better starting point.

Ready when you are

Let's build your iOS app.

Whether it's a new iPhone app, an iPad version of something you've already built, or an old iOS app that needs to stop crashing on newer devices — we'd love to talk. No sales script, no pressure, just a real conversation.
