iOSDevelopment services

One code base,
multiple devices

We produce the code in Swift, so it can be reused on iPhones, iPads, Macs and VisionPro devices. What changes is the UI - this is where our team of designers can help! Our iOS developers will define your interface and vary the UI depending on the device.

(And we can have some kind of image on the side with one “code base” and four arrows going to the direction of each types of device)

We create amazing apps with great designs. For every custom iOS app development project, we think about every button, text, and alignment before creating this UI in-app.

Our designs are implemented pixel perfect, and we try to animate each app as much as we can to create a wonderful user experience.

The Network

Almost every app we create uses a backend server and storage architecture which requires access via wifi or cellular networks. To that end, we always ensure that the app contents are presented to the user For example, if we can’t access a server because a user is in the subway or in the middle of a desert, we will always display a beautiful screen that will explain the connectivity issue and allow for as much offline functionality as possible.

Your users’ information is important to us, and we will protect them as much as we can to avoid any leak. Our iOS app development services include crypting user details on the device, using Face ID if needed, and we will help you build and protect any information as needed.

Our Stack


Swift is a powerful and modern programming language developed by Apple for building applications on various Apple platforms, such as iOS, macOS, watchOS, and tvOS. It is designed to be safe, fast, expressive, and user-friendly. We use it for every custom iOS app development project. 


SwiftUI is a modern and declarative user interface framework. It simplifies and enhances the process of building user interfaces by using a more intuitive and concise syntax. 

Our Process & Standards for Custom iOS App Development


We’re an iOS app development company that emphasizes collaboration, incremental progress, and responsiveness to change. We aim to deliver value to customers quickly and continuously by breaking down projects into smaller, manageable chunks. Communication is key to building great applications, so we work as one across each of our departments. This synergy brings efficiency and saves time to build better apps.

Coding Standards

iOS code can become quickly complicated and overwhelming as your application grows. We aim to define every flow possible from the beginning and work on top of those. We use MVVM and Viper-like architecture for custom iOS app development to reduce complexity. By dividing views in small chunks, each view has only the information it needs to work. This allows us to keep things simple from the beginning to the end of a project.

Pixel Perfect

The designs that you approve are the ones we are implementing - it won’t change and will absolutely match.

Quality Assurance is among the most important of our iOS app development services and ensures the success of a project. It focuses on identifying and preventing defects, errors, and issues in your applications before they are released to users. It is probably the most critical and important piece of our flow. We aim to have 80% test coverage of the business logic layer and the data layer. The UI is tested manually by our amazing QA team.

We build each of our applications while keeping performance metrics top of mind. Here are a few examples of what we are looking at while working on your applications to make them great: Launch Time, Response Time, Memory Usage, CPU Usage, Network Performance,Crash Rate, Battery Usage, App Size.


We release a new version of your app at the end of each Sprint. You can see it and use it. Each release is feature complete–we never release half-done code, and it is obviously fully tested.

To Summarize

A good app is an app that doesn’t crash. A great app is an app that doesn’t lag. An amazing app is an app that is awesome to use, that feels right into the hand, that has been tested properly, that works all the time. This is what a top iOS app development company like us does.

Relevant experience

Find your community

We’ve  worked on a number of apps with amazing designs, but Somwhere Good was very unique in its design and navigation. We built a brand new way of navigating an iOS app via SwiftUI. All animations and transitions were fully custom. We used custom images, buttons and views to define its UI and all of that while recording audio to create a new way to share and connect people.

Your turn to pitch

For this custom iOS app development project, we built a custom camera that records at 120 fps for Mustard. We needed to record at such a high speed to be able to analyze the pitches of the players properly. We had to take into account all the different types of iOS devices and solve (via code) the potential for device overheating during long durations of use.
