iOS Development

Apple’s mobile operating system is the most profitable platform for mobile app developers. For
that reason, it’s often the first place apps are released. Decades of traditional software
experience give Zco unique insight into best practices for user interface design, data security,
and development methodologies. We've been building apps for the iPhone, iPad, and iPod
Touch since their release, so iTunes App Store optimization is second nature.

Android Development

As the mobile operating system powering the majority of smartphones and tablets, Android is a phenomenal platform for reaching the maximum number of users. Android devices possess a wide variety of hardware components and technical capabilities, giving consumers and businesses a great deal of choice.

Windows Development

Microsoft moved away from its Windows Mobile platform to compete with iOS and Android, and the result was a common touch interface between phones, tablets, laptops, and desktops. Zco develops Windows Phone and Windows 8 apps with the same care as with every other mobile operating system - and all the desktop development in our background doesn't hurt.

Our Process

A step by step visual of the app development process

When you bring your application or content requirements to Zco, we first protect your intellectual property with a non-disclosure agreement (NDA). We then evaluate the feasibility of your project and provide an estimate. From then on, there’s constant communication between our project managers and you, our customer.

Creating an app or content requires continual reinforcement of each step. Your initial design is refined and then followed by professional development by our engineers. The next step is deployment, to internal testing or beta testers or end users. We provide long-term support to ensure that new operating systems are supported. Analysis of app usage and content consumption informs the next design iteration to improve your product.

As app developers for hire, we turn over ownership of all source code to you. We can assist with marketing and are always proud to link to satisfied customers on our website. We can also keep our relationship completely confidential – it’s totally up to you.

Learn more, including our app development costs, on our FAQ page.

Case Studies

App Development Company Zco

Our customers come to us with specific needs. Sometimes they want to solve a specific problem in their business. Sometimes they want to increase their brand recognition. And sometimes they simply want us to create something they can sell.

Whatever their goals, we always appreciate learning how we’ve contributed to a customer’s success. Months or years after we hand over source code, or simply in the process of providing continuous updates, we’re fortunate to get details on how an app, animation, video, or other digital asset has helped a client to achieve objectives.
