HipChat let's you bring your office, and your office mates, with you wherever you go. This app is for more than just chat, it allows video calls and screen sharing, all with IT security in mind.

Access your conversations from your desktop, laptop, tablet or smartphone. Create chat rooms based on specific groups of people you need to engage with, or specific projects you're working on.

Using a Twitter-like tagging system, direct questions and comments within a group chat to a specific recipient. Maybe throw in a funny GIF or create a custom emoticon to keep the mood light if you're dealing with an overly challenging project. Try it now for free or upgrade to the $2/month package to access all the awesome features. Once you have finished your chat, you may want to document the results.
