We help you balance cost, development speed, flexibility, risk, performance, scaling, and security to arrive at an efficient solution that meets your needs, budget and provides an amazing experience for your users.

React Native

Develop truly cross-platform mobile applications with JavaScript in a framework that leverages native platform SDKs for optimized compatibility. React Native uses the same design pattern as React, one of the most popular front-end web application frameworks to date. Building with React Native means building a real mobile app, you don’t build a “mobile web app,” an “HTML5 app,” or a “hybrid app.” You build a real mobile app that’s indistinguishable from an app built using platform native languages like Java, Objective-C, or Swift.

iOS development

For some applications native platform mobile development is the best and possibly the only way to go. If the majority of your user base is on iOS and prefers the high-end feel and features offered by Apple, or is designed for a specific device with unique capabilities. We have experience developing and deploying natively for iOS with Xcode using Swift and Objective-C.

Android development

For some applications native platform mobile development is the best and possibly the only way to go. Android users represent over 60% of the market here in the USA so if you want something that caters to this audience then a native android app could be the best choice for you. We have experience developing and deploying natively for Android with Android Studio using Java.

Xamarin development

Xamarin enables you to develop native Android, iOS mobile applications with a single shared C# code base. Not only do you have the power of .NET at your disposal, native platform libraries are also available through the built-in Mono framework with Xamarin. When leveraging Xamarin.Forms you are not just sharing C# business logic across multiple platforms, it is now possible to create one UI that maps to the native controls of Android, and iOS. This is how we create great cross-platform mobile applications regardless of what device your users happen to own.

QA and testing

Quality Assurance and Testing is regularly overlooked as something that is not needed if developers write good code. This is not how it works on our team! We involve QA right from the start all the way to and after launch. Our manual and automated testing make sure your users have a flawless experience each and every time.
