iOS app development for businesses

We design, build and publish custom iPhone and iPad apps for your business. We work with native Apple code, such as Swift, or with cross-platform technologies if you also need Android. We build your MVP in 2 months, and everything we deliver comes with a 1-year warranty backed by a contract.

  • Already have an iOS app that isn't working as it should? If you have the source code, we can take it over and get it ready for the App Store.
  • Currently, we manage more than 40 apps for our clients, saving them time and money.

Does your project include other platforms?

We also build Android apps and custom software to run your business operations.

What does building your iPhone app include?

We stay with the project from the first idea to the App Store. Every stage ends with something you can review, so you always know where your app stands.

  • Scope definition: what the first version (MVP) must solve and what can wait for a later release.
  • UX/UI design with your brand's look & feel, based on Apple's Human Interface Guidelines so the app feels at home on iPhone and iPad.
  • Development with native Apple code or a cross-platform approach, depending on what fits your project.
  • Backend, APIs and integrations with the systems you already use, such as payment gateways or your CRM.
  • Testing with real users through TestFlight before launch.
  • Submission from App Store Connect and support throughout Apple's review.
  • Weekly meetings with the development team and weekly progress updates.

Native Swift app or cross-platform for iOS?

A native iOS app is built with Apple's own tools: the Swift language, the SwiftUI framework for the interface, and Xcode to compile and ship it. It gets direct access to system features such as the camera, notifications, Apple Pay, widgets and Face ID, and it's usually the best choice when the iPhone experience is at the heart of your business.

A cross-platform app, built with a framework like Flutter, shares most of its code between iOS and Android. It makes sense when you need to be in both stores on a single budget and the app doesn't rely on very Apple-specific features.

Going native makes more sense if:

  • your customers mostly use iPhone, or your product lives or dies by the iOS experience;
  • you need Apple's newest features from day one;
  • you want the smoothest possible animations, camera work or on-device processing.

Not sure yet? On the video call we'll look at your case and recommend the approach that fits best.

How do you publish an app on the App Store?

Publishing on the App Store involves steps worth planning early, because some of them depend on your company's paperwork rather than on the code:

  1. An Apple Developer Program account in your company's name. To enroll as an organization, Apple requires a legal entity and a D-U-N-S number. That way your company's legal name appears as the seller on the App Store.
  2. Your App Store Connect listing. Name, description, screenshots, category, and the privacy details that disclose what data the app collects.
  3. TestFlight testing. You can invite up to 100 people from your team and up to 10,000 external testers. Each test build stays available for up to 90 days.
  4. Apple's review. Every app and every update is checked against the App Store Review Guidelines. According to Apple, on average 90% of submissions are reviewed in less than 24 hours.
  5. Launch and updates. Once approved, you choose when to release, and each new version goes through review again.

We guide you through every step so your app is complete when it goes to review.

Did your iOS project lose its developer?

If you have the source code, we'll review where it was left, fix what's missing and finish the app. Everything we deliver comes with a 1-year warranty.

What does Apple check before approving an app?

Many rejections can be avoided by planning for them during design. These are some of the App Store Review Guidelines worth keeping in mind:

  • App completeness (2.1). The app must be submitted finished, with no placeholder content, and if it has a login you need to give Apple a demo account.
  • Minimum functionality (4.2). An app that simply wraps a website can be rejected; it has to offer features and an experience that feel like an app.
  • Account deletion (5.1.1). If users can create an account in the app, they must also be able to delete it from within the app.
  • Login services (4.8). If you offer sign-in with third-party services such as Google or Facebook, Apple asks for an equivalent option that protects the user's privacy.
  • Payments (3.1). In most cases, digital features or content inside the app are sold through Apple's in-app purchase; in the US storefront you can also link to your own website for purchases. Physical goods and services used outside the app, like a food order, use other payment methods.

Does your business need an iPhone app?

An iOS app is worth it when it solves something your website or your current processes don't handle well. These questions help you decide:

  • Do your customers buy or book from their phones, and do you want to give them a branded experience?
  • Would you like to connect your online store to an app and sell through both channels?
  • Is your team still recording information on paper or in spreadsheets?
  • Do you need push notifications, offline use or phone features like the camera?
  • Do you want to stand out from competitors that only have a website?

Frequently asked questions about iOS app development

How long does it take to build an iPhone app?

It depends on the scope. We build the MVP in 2 months: a first version with the features that solve the core problem, ready to test with real users. More features come in later releases. On top of that, plan for Apple's review, which Apple says takes less than 24 hours for 90% of submissions on average.

How much does an iOS app cost?

The price depends on the number of screens, the integrations, the backend, and whether the app is iOS-only or also needs Android. That's why we quote each project after a discovery call, and we can work with monthly retainer payments or financing. Besides development, budget for the annual Apple Developer Program membership, which Apple requires to publish on the App Store.

Should the app be published under my company's account?

We recommend it. That way the app, its reviews and its sales data belong to your company. For an organization account, Apple asks for a D-U-N-S number, which you can look up or request during enrollment.

Can you take over an iOS app another developer left unfinished?

Yes. If you have the source code, we review its state, fix the issues that keep it from being published or updated, and take it to the App Store. It's common for an app that hasn't been maintained to need changes before it meets Apple's current requirements again.

Can you also build the Android version?

Yes. If you need both platforms, we assess whether a cross-platform app with a single codebase or two native apps makes more sense. Learn more about our Android app development for businesses.

What happens after the app is published?

Apple releases a new version of iOS every year, so an app needs ongoing maintenance to keep working well. Everything we deliver comes with a 1-year warranty backed by a contract, and we can stay in charge of updates and new features.
