Custom iOS App Development in Chicago

Looking to hire seasoned iOS developers or outsource your entire mobile project?

Whether you need to build your iOS app from scratch or re-design and upgrade an existing one - we have expertise and experience that can help!

iOS development has been at the core of our business since 2007 when Apple launched the iPhone.

As early adopters, we had experimented with app concepts, design, usability and features until we mastered the skills and became self-confident enough to offer ROI driven iOS solutions to businesses like you.

From developer's perspective: iOS is a great choice as it offers little configuration hassle thanks to the unification of OS and clear development guidelines.

How We Build iOS Apps

The Idea and Technical Requirements Spec

When you come to us with your app idea, we create a user story based on the initial input. The input can consist of app goals and mission, target audience, app vision, key features and functions, life cycle, monetization, etc. We also conduct the market research to identify the app’s USPs and competitive advantages. When there is a clear and shared vision of what kind of an app you're looking to develop, we create a detailed development project specification.

If you already have an app that needs an upgrade and quality improvement, we will review the app, ask questions, plan improvements and move to prototyping.

At this stage we guarantee the following deliverables:

Project scope with all UI screens
Project Plan (key deliverables, milestones and deadlines)
Design best practices
Test plan (incl. UI testing, unit testing, browser / device coverage, functional and regression testing)
Test report matrix

Prototyping & Future-Proofing

To visualize your future app and get a clear understanding of how it will perform and function, we employ wireframes and storyboard sketches. These wireframes and storyboards are linked to each other in order to identify what layout is most suited for the app.

Once the visualization is complete and you've given us the green light, we proceed with coding and iOS app design.

Besides gathering target audience feedback, app prototype is a great way to pitch your startup / project idea to investors or get a buy-in from your corporate leadership. Please note that Intersog offers app prototyping as a standalone service, check it out here.

iOS App Development

We are an Agile business that applies an iterative approach to building iOS apps. We divide the development project into iterations (periods of the same length -- typically, 1-2 weeks). At the end of each iteration, we will provide you with a test build.

We deliver two versions of your iOS application:

Pre-release version (alpha) - a functional app with major features for key user interview or focus group feedback
Revised release version (beta) that incorporates all comments from alpha version and provides a fully-fledged app for release approval

iOS App Design

Typically, the design is created after the functionality and development have been defined and agreed upon. We compile a list of what needs to be designed (icons, splash screens, tab icons, 2D/3D modeling, characters and other assets) and submit it to our mobile design team.

Beta Testing

At Intersog, we conduct tests within each iteration of the app development process, but we also perform a beta testing to check the compatibility with real life scenarios and user cases. By identifying errors, bugs and gaps, we are able to fix apps in a timely manner. This will allow for the release of a bug-free product, which will save you money by eliminating post-release bug fixing.

Release

After you accept a deliverable, we confirm that the app complies with Apple’s App Store policies and requirements. Once this is confirmed, we publish the app and optimize it to enable easy discoverability.

In order to launch an iOS app through the Apple App Store, we help you establish an iTunes Connect account. Once this account is setup, you can easily publish more apps using the same account.
