Roundly

Share what's going on around you to everyone nearby with just a few clicks. You can choose to share on either Facebook or Twitter or both at the same time as well. See what others nearby have posted on a map.

You can use it to draw attention to whatever is going on. Maybe you are hosting a party or some other event which is open for the public, use the app to draw attention. If you are company and are having a sale, make a post about it in the app and people who are nearby and using the app can easily notice you. If an accident has occured nearby, it might be useful to make others nearby aware of it. How you use the app is up to you. Have fun with it.

Everything that's happening might not be relevant for very long. Therefore you can easily set the duration for how long your post should show. If none is set, it will be up for 2 hours. By pressing the minus sign in the top right corner you can remove current posts manually.

Make your post more descriptive by taking a photo of what's going on and include it in your post.
