The ability for my team members from different countries with differennt languages or cultures can share their thoughts in our internal chatrooms without any translation issues! It's not free but I think it worth every penny you spend at least once when using this app since we have found so many benefits through its usage as well!! No dislike about anything yet because i haven't encountered problems during implementation stage like some other apps do :( But there were no negative feedback either while doing research before deciding which one would be best fit into organization culture/environment etc..
Just try them out if your looking around :) My Team has been communicating more efficiently internally than ever by sharing each others work status via acceptance mission application within minutes instead spending hours typing messages over email system only.
