Mobile App Development

Build An App or Mobile Responsive Website?

Mobile apps are great for actual applications...software that collects data, processes transactions, ecommerce, etc. We are not married to one technology. We can build native apps for Android or iOS or use platforms, such as PhoneGap and Appcelerator to speed development on cross-platforms. We pride ourselves in selecting the right technology and approach for the client's needs, budget and timeline. We have also advised clients to not build an app as it was not practical for their situation. For example, we had a company wanting to build a mobile data collection app, but there existing numerous software-as-a-service solutions, which we advised them to implement versus building from scratch.

We Make It Simple

For "brochure" websites, you typically don't also need an app. Our philosophy is to keep it simple. We build you a mobile website that can be downloaded as a mobile app for iPhones, iPads, Android phones or tablets. It can also be viewed as a website on your computer (with modern Internet browsers) or as a website on smartphones/tablets (which all use modern browsers).
