Hash#는 지금 우리 도시에서 벌어지는 모든 일을 지도 위에서 실시간으로 만나는 앱이에요. ● 지금 밖에서 뭐가 벌어지는지 한눈에 봐요 - 지도를 열면 지금 일어나는 일들이 점으로 빛나요. - 유동인구를 핫플레이스 별로 실시간으로 알 수 있어요. - 인파, 문화·행사, 긴급·사고, 팬덤까지 카테고리로 골라보세요. ● 오늘 어디 가야 할지 골라드려요 - 동네별로 들어가면 그 안에서 벌어지는 일들이 정리되어 있어요. - 인기 이벤트와 카테고리 추천으로 방황 없이 바로 출발해요. ● 거기 지금 어떤지 미리 확인해요 - 이벤트마다 열려있는 채팅방에서 현장 사람한테 바로 물어보세요. - 웨이팅, 분위기, 사람이 얼마나 모여있는지 까지 출발 전에 확인할 수 있어요. ● 사진 한 장이면 AI가 상황을 정리해드려요 - 눈앞에 뭔가 벌어지는데 뭔지 모를 때, 그냥 찍어서 올리세요. - AI가 사진을 보고 지금 무슨 일인지 한 줄로 알려드려요. - 같은 이벤트가 이미 있으면 자동으로 합쳐지고, 없으면 새로 만들어져요. ● 내가 다닌 곳이 나만의 지도가 돼요 - 올린 순간들이 모여 빛으로 채워지는 나만의 지도가 만들어져요. - 추억을 해시로그로 정리하고 친구의 지도도 자연스럽게 만나요. 문의하실 점이나 제안하고 싶은 게 있으시면 언제든 알려주세요. 열심히 듣고 있어요 :) 사랑합니다 :)

Sometime helps you meet university students in Korea, starting with a simple chat. Browse profiles and send a like. Once you're both interested, start a one-to-one chat. Into Korean culture, K-pop, K-dramas or the Korean language? Where Korea–Japan matching is available, messages show the original text alongside a translation, so you can start talking even if your Korean is still basic. Privacy you control - Block people from your contacts. - Exclude your own school or department if you want. - Profile photos carry a watermark. - Report or block anyone who makes you uncomfortable. Verification - Phone number verification at sign-up. - Profiles that completed university verification show a badge. Good to know - Some features, such as certain likes, starting a chat, rematching and translation, use gems. You can check the cost and conditions before using each feature. - Contact blocking and school or department exclusion reduce the chance of being seen, but can't prevent it in every situation.
