Not a stranger — someone your friend thinks you'd really get along with. NINIGU brings the familiar tradition of being introduced through friends into an app built around the people you already know. [Friends] Add the friends you know in real life. Everything on NINIGU starts from these real connections — there is no browsing of strangers. [Introductions by a trusted friend] Friends can create an Introduction Circle of friends they know well and vouch for. When you'd like to be introduced to someone in a friend's circle, your request goes to that friend first — not to the other person. Your friend decides whether the introduction makes sense, adds a short note, and only then passes it along. A conversation starts only if the other person also says yes. [Be the matchmaker] You don't have to be looking for anyone yourself. Many people use NINIGU simply to introduce two friends who might get along. [Plaza] Join hobby boards, share posts and photos, comment, and plan meetups with people who share your interests. Save meetup posts to your calendar. [Meetings] Friends can arrange small group meetups together and chat in a shared room before meeting. [Profile] Share your interests, values, and a favorite song, so friends can introduce you thoughtfully. [Safety] • Introductions always go through a mutual friend and require both people to agree • Report and block from any profile, chat, post, or comment • Users must be 19 or older Sometimes the people who know us best make the most meaningful introductions. NINIGU — introductions from people you trust.

New in Korea, and everything is in Korean? K&U is built by international students at Kyungpook National University for the ones arriving after them. It started at KNU and now covers five campuses: KNU, Korea University, Korea University Sejong, Yonsei and Pusan National. TODAY'S MENU What the campus cafeterias are serving, in English - ten at KNU, four at Korea University, with the dish each cafeteria recommends marked. Refreshed every morning, so it is today's menu and not last week's. NOTICES THAT MATTER Dormitory payment deadlines, ARC appointments, health insurance, scholarship calls. The announcements that cost you money or a visa if you miss them, without wading through a Korean noticeboard. Turn notifications on and the new ones come to you. THE CAMPUS MAP More than a hundred places across the five campuses - where to eat, where to buy things, where the international office is. Tap any place for directions in Naver Maps, which is what actually works in Korea. Korea University's list runs to fifty buildings and says which cafe, bank or convenience store is inside each one. ASK ANYTHING A board where students answer each other. Which gate is closest to the metro, how to log in to the library, whether you can ship boxes to the dorm before you arrive. It is the same board the K&U websites use, so an answer reaches everyone at once - and a reply to your question comes back as a notification. FIVE CAMPUSES, ONE ACCOUNT Pick your campus and everything follows it: menu, notices, map, board. Sign in once with email, Google or Apple; the same account works on every campus and on the K&U websites. Free, no ads, no advertising ID, and it never asks for your location. Not affiliated with the universities. Built by students who needed it first.
