Pros:

• This application would be a great help to businesses, no need for skype or any video conference software, you can have an interactive conversation or presentation between you and potential customers/listeners.
• This app can be a great aid especially for manufacturing and engineering teams, wherein for situations of assembly or issues in manufacturing, no need to capture photos, a meeting can be set up for the engineering and the manufacturing, to see the areas in the assembly that have issues, thereby reducing travel costs and reducing lead times. (been working in this type of industry, we use skype and ms outlook for conversation and it's very tedious)
• Free to download application which is available in Android and iOS devices.

Cons:

• None for this application , this is such a very important to have application for those who are into socializing such as in businesses.

Great hunt @rosatravels!
