Responsive Web Application Development

Native mobile apps are a perfect fit for many businesses, but they are not the best or most cost-effective solution for every project. That's why Rectangular Software also provides responsive web application development services. Using state-of-the art HTML5 and JavaScript, we build Django-powered web applications that work flawlessly on the full range of web-enabled devices from the smallest phones to the largest desktop computers.
