Our Mobile App Development Services

iOS App Development

Since 2008, Zco Corporation has been innovating in order to offer one of the most comprehensive custom iOS app development services on the market. Previously developed through languages like Objective-C, the standard for high performance is now Swift, which offers a whole new level of smooth user experiences. Whether it’s the latest iPhone, iPad, or Apple Watch, our mobile app developers have the experience necessary to create a stand-out product.

Android App Development

Our developers have extensive experience producing custom native apps for Android, the most widely used mobile operating system in the world. Your project can run across all manner of Android devices using Kotlin and Java-based technologies. With Zco Corporation, you can expect design expertise that will allow you to target a wider audience while standing out from the crowd.

Native App Development

Custom native app development can harness mobile devices’ full power and performance through specialized APIs and programming languages. Because of this, native apps can be as fast, efficient, and smooth as possible. It’s also the best option to utilize device functions, like GPS or Bluetooth, as harnessing a device’s sensors is more difficult in a hybrid environment. The Zco Corporation native app development service fits both startup and enterprise-level clients.

Hybrid App Development (Cross Platform)

With a blend of mobility and cross-platform compatibility, our custom hybrid app development service is the perfect choice for clients seeking to maximize their project’s installation base while minimizing the overall cost of their project. At Zco Corporation, we can use our experience in React Native, Xamarin, Flutter, and other hybrid technologies to craft multi-platform mobile apps.

Progressive Web App Development (PWAs) 

Progressive Web Apps, or PWAs, are created with web development languages such as HTML 5, CSS, and JavaScript. They are often mistaken for Hybrid apps due to their cross-platform nature and the similarities in development languages. Our custom web app development services can even produce apps that have enhanced offline functionality. PWAs are also an excellent choice for enterprise application development as web apps can be used across devices and do not require downloads or device-level storage.

Our Mobile App Development Process

Step 1

In-Depth Assessment

Every custom software project begins with an in-depth assessment of your project’s requirements and its software life cycle. An account executive and project manager will work with you to determine the scope of your project and develop a plan of action.

Step 2

Technical Requirements

We’ll help you determine security and encryption requirements, the cost of custom software development, database and cloud software, as well as integration with the hardware and software development services your company utilizes.

Step 3

Agile Development

Through agile software development, your project is built over several iterative cycles. New builds of the project are regularly shared with you to gather feedback and integrate your recommendations into the project.

Step 4

Quality Assurance

Throughout active development our quality assurance teams ensure the product is rigorously tested, seeking out and eliminating any bugs found. When the software is rolled out to your user base, it will be ready for prime time.

Step 5

Deployment

At the end of the QA process, your app is deployed and made available on its platform’s respective marketplace for public use. From here you can promote your app, get its first users, and grow your business.
