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.

Making friends in New York shouldn't be this hard. Sally is a members-only social app for New Yorkers (soon to be other cities) who are tired of scrolling and want to actually meet people — built around shared interests, not endless swiping. HOW IT WORKS Open Star Packs — interest-based worlds like Coffee Lovers, Cocktail Connoisseurs, Film Fanatics, and Bookaholics. Pick the ones that are you, and answer one honest question in each. Those answers become your Star Qualities: the truest version of you on your profile. Sally matches you with people who genuinely share your world — then nudges you to actually go do something about it. Grab coffee. Hit a bar. Find a bowling lane. There's a map where you star the spots that make your city yours, and see where your community goes too. WHY SALLY IS DIFFERENT - Members-only — every profile is reviewed by a real person - Interest-first — you match on what you actually love, not just a photo - Built to get you offline — the goal is a real hangout, not a longer chat - No infinite scroll, no performing — just people worth meeting Whether it turns into a friendship or something more is entirely up to you. Sally is free to use. Optional in-app purchases are available but never required. Now go meet someone. Stay whimsy. Met Through Sally LLC · New York, NY
