Community helps you find an event in suggested location, get information about local companies, vote, take a part in polls and surveys, and meet people in you area.  Community allows you to chat with your friends, collaborate with your colleagues or clients, publish important messages in channels, schedule events and invite your friends and customers to attend them.  Community supports group chats so you can talk with a group of your friends, family members, colleagues, business partners or any other group of people.  Survey your audience through polls and then share your poll results in group chats and channels.  Community allows your to connect to thousands of people from all over the world.  You can get in touch with event planners and talk to participants in group chat.  Community will remind you about event's date and time.  You can share your text messages, photos, GIFs, video or any other type of files.  Create channels and share them with other people.  With Community, you don't have to pay to stay in touch.  If your smartphone connected to a mobile network (4G/3G/2G/EDGE), the app will use that connection.  Tell the world (or small audience) about your work, research, products and services.  Make Community your own mass media.  Community is completely free.  Find out what your audience wants, get a feedback or do a research.  If your device is connected to the Internet via a wireless network, the app will use that network.
