Custom Mobile Application Development

Custom apps are shown in three devices – United States mobile app development services

The mobile app is becoming as important in establishing a business’ credibility as the website was a few years ago. Branded apps establish a deeper connection between company and customer, and can take many forms: mobile commerce portals, service directories, even games.

Developing mobile apps is an engineering challenge distinct from desktop software development. The interface, storage footprint, and data access must all be tailored to the mobile device. The Zco team of app developers lives and breathes custom mobile application development, and we can build apps for any mobile platform that interact with backend systems and cloud services.

iPhone and iPad App Development

Apple produces the single most popular smartphone and tablet lines: the iPhone and iPad. Accordingly, apps for the iOS platform bring in large amounts of revenue. In 2013, customers spent more than $10 billion on the iTunes App Store, including both paid apps themselves and paid in-app purchases. [Source]

To date, app developers have earned $15 billion through the App Store. The amount of money saved by using mobile technology or earned by attracting business with a mobile app is above and beyond this direct figure. Working with seasoned iPhone and iPad app development companies can give you a competitive advantage. Zco’s portfolio includes dozens of iOS apps, from simple event guides to complex secure cloud data access software.

Android Development

More people use Android than any other smartphone operating system. The open platform is available on a multitude of different smartphones and tablets from many manufacturers, including Samsung, HTC, Motorola, LG, and more. This open philosophy means that Android is in the hands of a wide variety of workers and consumers.

Zco is a leading mobile application development company, and our developers possess years of experience with Java, the programming language used to create Android apps. Branded apps, games, enterprise tools, and augmented reality are all possible. As more hardware is built into the latest Android handsets, even more functionality will be unlocked.


Windows Development

The world’s dominant desktop operating system is making serious inroads on mobile devices. Microsoft’s own tablet, the Surface, is a model for blending business productivity with media consumption. Nokia’s Windows Phone line includes high-resolution cameras and speedy hardware.

Zco was one of the first developers to use Microsoft’s .NET framework in 2002. We’re still committed to the Windows environment as it transitions to mobile devices.


BlackBerry Development

As one of the pioneers of the smartphone revolution, BlackBerry has a dedicated fanbase. The company might not enjoy the commanding market share it once did, but app development for the famously secure platform continues. We are one of the few mobile app development companies still committed to developing innovative new apps for BlackBerry devices.

In fact, makers of Android apps can often add BlackBerry compatibility with minimal time, cost, and effort. The BlackBerry Runtime for Android examines and repackages existing code. For any non-compliant code, Zco’s expert developers can port the needed functionality.

Our Mobile Application Development Process

Zco Corporation is one of the largest custom mobile app development companies in the USA, and in the world. We work with app development projects large and small.  Most clients come to Zco with functional requirements – what the finished app should do. Our comprehensive mobile app development services allow us to develop and integrate a user interface, graphic design, 3D animation, game mechanics, and communication protocols from there.

All customers work with an Account Executive and Project Manager. After a Non-Disclosure Agreement (NDA) is signed by all parties, a Statement of Work (SOW) is drawn up. Clients receive constant updates on the status of the project, and a final build is given to them for approval before upload to the appropriate app stores. Marketing assistance is also available.

  • Barton Tiles

    The Barton Reading & Spelling System aims to improve the spelling, reading, and writing skills of children, teenagers, and adults with dyslexia and other learning disabilities. It consists of ten levels, each with tutor training DVDs, complete lesson plans, and color-coded tiles.

    The Barton Tiles app is designed to save tutors using the Barton Reading & Spelling System at least 10 minutes each session. Words and tiles are pre-loaded for each lesson, and there’s no cumbersome tile cleanup. Student tracking functionality stores contact information, notes, current level and lesson, and even a photo of each student.

  • GiGi

    Messaging between users is a critical part of the mobile experience, and all too often, it’s vulnerable to interception by hackers, network sniffers, and data miners. Piecemeal solutions exist, but few attempt to integrate multiple forms of secure communication into one app.

    GiGi ensures security for messages, whether they are texts, pictures, videos, or emails. A single secure username provides access to one-to-one or group multimedia conversations. A visual dashboard simplifies navigation, and randomly generated PINs protect the user from using codes that are easy to guess. Automatic deletion of sent and received messages after pre-set time periods keeps communication history away from prying eyes.
