The cost of a weak iOS app

Is your iOS app letting users down?

iPhone users notice the difference between a real native app and a cheap shell. If any of these sound familiar, native iOS development is the fix.

A sluggish app that feels cheap

iPhone users have high expectations. An app that stutters, lags on launch or drops frames feels broken and gets uninstalled. Native Swift delivers the smoothness users expect from iOS.

An app that ignores iOS conventions

Apps that fight the platform confuse users. We build to Apple Human Interface Guidelines so your app feels at home on iPhone and iPad, not ported from somewhere else.

App Store rejections you cannot decode

Apple review rejects apps for reasons that are hard to interpret. We know the guidelines and the common traps, so your app gets approved without rounds of rejection.

Missing the latest iOS capabilities

Widgets, App Clips, Live Activities, SharePlay and the newest APIs set modern apps apart. We build with current SwiftUI and the latest platform features, not last decade tech.

Security and privacy gaps

iOS users care about privacy and Apple enforces it. We implement Keychain, secure storage, proper permissions and privacy compliance so you pass review and earn trust.

An app that breaks every September

Every iOS release can break an unmaintained app. We build for forward compatibility and keep your app current as Apple ships new versions and devices.

Why choose us

iOS development done the right way

Anyone can wrap a website in an app shell. We build genuine native iOS that feels fast, passes review and earns five stars, then keep it current as Apple evolves. These are the standards behind every app we ship.

Start your project
  • Swift and SwiftUI specialists

    We build native iOS in modern Swift, not a web view in a wrapper. The difference is in every tap and scroll.

  • We follow Apple guidelines

    Apps built to the Human Interface Guidelines feel native, pass review faster and earn better ratings.

  • Performance you can feel

    Fast launch, smooth scrolling, light on battery. We profile and tune until the app feels quick and natural.

  • We get apps approved

    We know what Apple review looks for and prepare accordingly, so your launch is not held up by rejections.

    Widgets, Live Activities, App Clips and the newest APIs, used where they genuinely improve your app.

  • Privacy and security first

    Keychain, secure storage, least-privilege permissions and privacy compliance built in, exactly as Apple expects.

    We test on actual iPhones and iPads across OS versions and screen sizes before anything ships.

  • Current every September

    We keep your app ready for each new iOS and device, so it never breaks when Apple ships an update.

Client words

Trusted by founders who ship on iOS

The SwiftUI app they built feels genuinely premium. It launches instantly, the animations are buttery, and our App Store rating sits at 4.8. The HealthKit integration was flawless. Worth every penny over a cheap cross-platform shell.

FounderHealth startup, United States

They got our app through Apple review first time, which our previous team never managed. Sign in with Apple, Face ID and secure storage were all handled properly. Our users trust the app and it shows in retention.

Product ManagerFinTech, United Kingdom

They added Live Activities and a home screen widget that our users love. Every iOS update since launch has been handled before it became a problem. The app just keeps getting better.

Questions, answered

iOS app development FAQs

How much does it cost to build an iOS app?

Most native iOS app projects land between $15,000 and $100,000. A focused app sits at the lower end; an app with a custom backend, complex features and deep Apple integrations sits higher. Every quote is itemized before work begins.

How long does iOS app development take?

A focused iOS app typically takes 10 to 18 weeks from design to App Store. Larger apps run longer. You see designs early and a TestFlight build every week so you can try it as it develops.

Native Swift or cross-platform for iOS?

Native Swift gives the best performance, the truest iOS feel and immediate access to new Apple features, ideal when iOS is your priority or the app is demanding. Cross-platform (React Native or Flutter) is more cost-effective if you need iOS and Android together. We advise based on your priorities.

Do you handle App Store submission?

Yes. We prepare your App Store listing, screenshots and metadata, handle the submission and manage Apple review, including resolving any rejections, so your app gets approved and live.

Can you integrate Apple Pay, HealthKit and other Apple services?

Yes. We integrate Apple Pay, Sign in with Apple, HealthKit, CloudKit, Maps, Wallet, push notifications and the wider Apple ecosystem as your app needs.

Do you design the app or only build it?

Both. We provide iOS UI/UX design following Apple Human Interface Guidelines, from wireframes to a polished, prototyped interface, or we build from your existing designs.

Can you build the backend for my iOS app?

Yes. We build the APIs, database, authentication and push notification infrastructure your app needs, or integrate with your existing backend and services.

Can you update or modernize my existing iOS app?

Yes. We take over existing apps, migrate legacy Objective-C to Swift, modernize aging codebases and add features, all while keeping your current users and ratings intact.

Will my app support iPad?

Yes if you want it to. We build universal apps optimized for iPhone and iPad, and can extend to Mac with Mac Catalyst, from a shared codebase.

How do you keep the app working after iOS updates?

We build for forward compatibility and, on a maintenance plan, test against each iOS beta so your app is ready before the public release. Most issues are fixed before your users ever see them.

Do you do App Store Optimization?

Yes. We optimize your app title, keywords, screenshots and listing to improve visibility and downloads in the App Store, and refine it based on performance.

What happens after launch?

Every project includes a handover and a warranty window. Most clients move to a maintenance plan covering OS-update readiness, monitoring, crash fixes and new features so the app stays current.
