Ping me is an application that allows you to send messages visible to anyone within five miles of your location. These messages disappear after 15 minutes. Other features include:
Follow user profiles by swiping left on any of their pings. Stop following any user at any time.
Make your profile invisible to hide your profile from other users that follow you.
Delete your activity and profile data permanently at any time.
No registration required.
Remember that every ping you send is visible to everyone in range. So be mindful of any information you share!
