With the hardware becoming more advanced, a wide variety of software is now usable on a mobile device. The advanced hardware has allowed developers to create detailed software that was not before achievable due to the simplicity and restricted nature of mobile devices of the past. Development tools were made to make the process of creating software for mobile devices a lot easier because the more that developers want to add, the more complex the software becomes without the tools. These tools have made developing software for mobile devices quicker and easier, and with the more advanced hardware on top, a lot of developers have started creating applications that could not have been possible on mobile before. Lots of organisations have taken advantage of the advanced technologies in mobile devices by creating apps which also allows them to keep...

This can be devastating for an organisation because it would make the job of figh...
