Every now and then we like to survey some of the best mobile apps available, as the software industry is constantly in flux with new products being released and others going extinct. One of the fastest growing areas in the app business is video conferencing, which is quickly becoming as ubiquitous in the business world as staplers and smartphones. We've assembled a list of some of the best products available, which you may want to consider integrating into your company's operations in order to streamline workflows and foster better relationships between coworkers.

• ooVoo -- It has a strange name, but make no mistake: The intuitive, minimalist interface of this app, which allows for group video chatting sessions, will fit naturally into your company's communications procedures, meaning you'll spend less time trying to book a conference room and more time actually working.

• Skype -- Most people associate Skype with students keeping in touch with their family while studying abroad, or employees communicating with family while on a business trip. In other words, it's often thought of as an app for your personal life. But in fact, it is just as useful for business looking to increase collaboration between employees. The latest update to the iOS version of this app includes unlimited, free video messaging, meaning you can send video snippets to coworkers if you simply need to remind them of an upcoming deadline or project.

• Tango -- This service is a little limited in the sense that you can only video chat with other users who have Tango, but it is free and unlimited, meaning that those group sessions that go on for hours won't dent your budget.

PortableOne carries a wide range of mobile iOS devices, including the iPad 4 and iPad mini, which will allow you to take these video conferences wherever you need them.
