  • iOS App Development

    Apps developed for the iPhone and iPad are most common primarily due to their popularity as a preferred mobile device and also due to cool user interfaces and their efficient functionalities.

    At Quadrant we have an expert team of iOS app developerswho are highly proficient with various programming languages and tools like iOS, Mac OS X Framework, Objective C, C++, Xcode, Cocoa touch, Cocos2d etc.

    Our services include:

    Market Assessment

    Competitive Assessment

    Application Architecture Design

    Application Development & Testing

    Application Maintenance & Upgrades

    How we do it?

    We follow best practices and conventions in iPhone app development from design to support.

    User Interface:

    We first draft the user interface on paper, develop a prototype app interface to validate it on the device.

    Application Architecture

    We follow the iOS App Programming Guide in building a valid application architecture and then implement the initial idea in a complete application.

    Performance

    In order to launch the application sooner, we avoid premature code optimization and write code that is clear. We use the application profiling tools supplied with the Xcode environment.

    Development

    We write modular and GUI tests so we can make changes to the application, without fearing to break some old functionality by chance. When you create a project in Xcode, it automatically makes a separate configuration for running tests.

    Teamwork

    We ensure proper coordination between the developer, customer and tester to ensure effective task management and timely delivery.

  • Android App Development

    Android app is becoming more and more ubiquitous today due to the popularity of the Android phone across the world. Android is the most suitable platform for companies new to mobile apps due to its utility and more importantly, the underlying architecture is open source due to which new releases and updates are introduced quickly and the entire platform is available for customization.

    Unlike other mobile platforms, Android applications can be distributed in a variety of ways like third-party application stores (most notably Google’s Android Market) and you can also create your own distribution channels: for vertical market application purposes, to develop new application stores, and even put it behind corporate walls.

    At Quadrant we have an expert team of Android app developerswho are highly proficient with JAVA, Android API's, Google API's and other programming languages.

    Our approach is client centric and we do due diligence in understanding the business requirements prior to designing the app. We cater to all industries.

  • HTML5 App Development

    HTML5 or web app has created a new revolution in the world of mobile app development and is a good alternative to native apps. The key benefit of HTML5 is that it is platform agnostic meaning you can read an HTML5 webpage on an iPad, iPhone, Android phone, Windows phone, Blackberry etc. Secondly, it is cost effective from a development point of view as you do not have to write separate code for each mobile platform. Finally, you do have to deal with the hassle of downloading and installing apps because the mobile responsive pages are directly accessible from any mobile platform.

    At Quadrant we have an expert team of responsive website (web app) developers who are highly proficient with HTML5.

    Our approach is client centric and we do due diligence in understanding the business requirements prior to designing the web app. We cater to all industries.
