iOS app development

Native apps for iPhone and iPad that make the most of Apple's ecosystem, with the polished design its users expect.

Why build an iOS app

iOS app development opens the door to iPhone and iPad users – a demanding audience when it comes to design and quality, used to apps and to buying on their phones. Depending on who your customers are, being on the App Store can make all the difference.

An app gives you a direct, always-on channel to your audience: notifications, one-tap access, offline features and a far smoother experience than a website. At OnClick we design and build iOS apps for businesses that want to offer customers a better service or give their staff a tool for working on the move. If you also need to reach Android users, we plan for it from the outset as part of our mobile app development service.

We speak Apple's language

Good iOS development means mastering the platform's tools and rules.

01

Swift

Apple's modern, safe, open-source language. It's the foundation of our new native apps.

02

Objective-C

The original iOS language. We use it to maintain and evolve existing apps, and combine it with Swift where needed.

03

Xcode

Apple's official development environment, where we design, code, test and sign every app.

04

Apple's design guidelines

We follow the Human Interface Guidelines so your app feels natural to any iPhone or iPad user.

What your iOS app can do

A native app has access to everything the device can do, so it can deliver experiences a website simply can't.

We design every feature with the user experience in mind: it's not about having lots of features, but about making the essential ones effortless to use.

  • Push notifications for alerts and offers
  • Offline mode with later synchronisation
  • Camera, barcode and document scanning
  • Geolocation and maps
  • Secure sign-in with Face ID or Touch ID
  • In-app purchases and payments
  • iPad-optimised versions
  • Connection to your ERP, CRM or website

How we develop your iOS app

  1. 01

    Idea and scope

    We listen to your idea and define the goal, the users and the features of the first version.

  2. 02

    Prototype

    We design the screens and navigation as an interactive prototype you can try before we code.

  3. 03

    Native development

    We build the app in Swift with Xcode, together with any back end and APIs it needs.

  4. 04

    Testing on real devices

    We test on a range of iPhone and iPad models and share beta versions through TestFlight for your approval.

  5. 05

    App Store publication

    We prepare the listing and manage Apple's review until your app is live.

  6. 06

    Maintenance

    We update the app for each new version of iOS and keep adding improvements.

Security and privacy by design

Apple is strict about privacy – and so are we. We're certified under Spain's National Security Framework (ENS):

  • Encrypted communication between the app and the server
  • Secure on-device storage of credentials
  • Minimal permissions, clearly explained to the user
  • Compliance with GDPR and App Store policies

Frequently asked questions

How long does it take to develop an iOS app?

It depends on complexity. A first version with the essential features can be ready in a few months. After the initial analysis we give you a schedule broken down by stage.

Do I need an Apple developer account?

Yes – to publish the app under your company's name you need an Apple Developer Program account. We'll help you set it up and configure it.

What if Apple rejects the app?

We know the App Store review guidelines and take them into account from the design stage. If Apple asks for changes, we make them and resubmit the app.

Can you build the same app for Android?

Yes. We can develop a native Android version or propose a hybrid app that runs on both platforms from a single codebase.

Do you maintain apps built by other developers?

Yes. We review the code, explain the state it's in and update it, whether it's written in Swift or Objective-C.
