What is UNATION?
UNATION is an app that makes it very easy to discover and promote events.
What do you mean by discover events?
It’s simple, really. After you download and join UNATION from the iTunes App Store or Google Play Store, or join through our desktop app, when you sign in you will land on the ‘Discover Events’ feed, where you can begin scrolling, filtering or searching for events near you.
What do you mean by promote events?
On the UNATION app you can create public events, add those events to searchable categories, share those events to your favorite social accounts, send those events to your friends or customers over email, and even text those events to the people who are interested in attending.
How can I access UNATION?
Currently, UNATION has an iPhone app, an Android app and a desktop app. To get our mobile app, simply search UNATION in either the iTunes or Google Play Stores, or just go to UNATION.com.
