PostRing's timeline isn't just one. A timeline that expands with each location. A world that's not just one is far easier to connect in. PostRing is a minimal social app designed for casual, location-based conversations. Posts, called "Rings," are shared only with people within a 10km radius of the poster and fade away over time, like a friendly chat on the street. *Note: This app is not primarily designed for real-time location sharing. Key Features -Post and view Rings only at your current location or at registered FavoriteLocations -Posts and DMs reset automatically every Wednesday at 0:00 JST, supporting your right to be forgotten -Share everyday thoughts in places you care about, with timelines that naturally disappear after a week How It Works -Post Rings from your current location or any registered FavoriteLocation -View Rings posted within a 10km radius of that location -Spread Rings by “Chaining” them to other locations -See how Rings spread on a map with Chain history -Use privacy options to hide your location or prevent sharing Use PostRing to… -Share your thoughts freely in places you love -Connect casually with nearby people, while traveling, or at events -Discover and share local events or small business info Features List -Save favorite places as FavoriteLocations to post/view from them -Use photos’ metadata to register places as FavoriteLocations -Attach location data to Rings when posting -View Rings within 10km of selected location -Slight location randomization for privacy (enabled by default) -Hide location or disable Chain sharing per post -View a map of where Rings have spread via Chain -Add users to your Friend List (no follow/follower system) -View Rings from friends and replies in dedicated tabs -Send and receive DMs -Attach images to Rings and DMs -Report or block/unblock users -Favorite Rings or browse this week’s posts -Receive announcements from the PostRing team -Premium: View Rings within a 50km radius -Premium: Save up to 50 FavoriteLocations (Free: 5) -Premium: Register up to 5 FavoriteLocations directly from the map Start conversations freely and casually from your location with PostRing.
