This app makes it easy to do multi-person video or audio conference calls on your smartphone. Once you sign-up for a free account, the app offers a simple interface with three tabs: Created Rooms, Joined Rooms and Meeting Logs. The plus sign lets you create a new room or join an existing one.

You invite others to join your room with a link via social media, email, SMS or just tell them the room name. Note that this only creates a meeting room — once you have all members, you can initiate a video or audio conference call. The app then gives you the option to invite all or select some people from the room for the call — you can even control if everyone can speak or only the room owner will speak (others only listen).

It gives you an access code that has to be shared with others to join in for the conference call. Any user can mute audio or switch off the video in the meeting while the admin can even lock the room to prevent anyone else from joining.
