A-CHA!: Your crew in Korea

Landing in Korea is exciting. It is also a blur of paperwork, empty rooms, and group chats you were never added to. A-CHA (ACHA) is the all-in-one app that gets you past that first month — and into a crew. Built for international and exchange students living in Korea, ACHA makes campus life simple. Everything is in English, with Korean one tap away. MEET YOUR CREW Join your school lounge and your country lounge the moment you sign up. Chat in real time with translation built in, so a language gap never ends a conversation. Find people who landed the same semester you did — the ones still figuring it out too with A-CHA. BUNGAE — SPONTANEOUS MEETUPS Free tonight? Post a bungae. Coffee, tteokbokki, a walk along the Han, karaoke after class. Anyone nearby can join, and the meetup opens its own chat room so plans actually happen instead of dying in a group thread. CAMPUS & CITY EVENTS An official calendar of what is on: campus festivals, city events, seasonal things you would only hear about from a Korean friend. Filter by your school, save what you like, and see who else from the ACHA community is going. FIND A ROOM (HOUSING) Listings from licensed Korean real-estate agents, not scraped guesswork. - Search by campus and see walking time to your university - Map view with price pins - Filters for deposit, monthly rent, one-room, officetel, goshiwon, share house - Foreigner-friendly and one-semester-lease listings marked - A brokerage-fee calculator that shows the legal maximum, so you know what an agent can actually charge you Signing a Korean lease in a language you are still learning is hard. A-CHA makes it easy. SHOP & ESSENTIALS The stuff you need in week one, without hunting through Korean-only sites: bedding, a drying rack, a multi-tap, towels, a kettle. Plus Korean gifts to send home. Checkout in English, delivered straight to your door. SPLIT THE BILL Shared a taxi, a chicken-and-beer night, an Airbnb for a trip? Settle it right inside the chat where it happened. No spreadsheet, no awkward reminder text. LIFE IN KOREA GUIDE Practical guides written for someone who just got here: banking, phone plans, the hospital, trash rules, transport. Plus nearby pharmacies and clinics that are open right now. BUILT ON TRUST, NOT ANONYMITY A-CHA (ACHA) is semi-real-name. You are a nickname, a nationality, and — if you choose to verify — a school. Enough for someone to trust you at a first meetup, not enough to expose you. - Report and block anyone, at any time - Zero tolerance for harassment, hate speech, scams, and impersonation - Reports are reviewed, typically within 24 hours - You control what your profile shows: nationality, school, stay dates, intro - Delete your account, and your content, whenever you want WHO IT IS FOR Exchange and international students at Korean universities — Seoul, Gyeonggi, Incheon and beyond. Whether you are here for a semester, a year, or a degree. Also useful before you arrive: browse rooms and events on ACHA while you are still packing.
