A website is typically a small collection of content pages intended to disseminate information. In contrast, a web application is a software that is delivered over the web and interacts with users for its needs. Increasingly, it is just not enough that these software be delivered over web alone, but cater to the growing number of smart phone/tablet users as well. Lot of applications are being developed with a 'mobile-first' strategy these days.
5G has designed and developed complex web applications, responsive designs that work well across multiple platforms, cross-platform applications that are 'developed-once', but delivered natively to multiple platforms as well as developing for native iOS and Android platforms.
