This is ONYU, a GPS recording app for Korea's mountains and trails.
Until now, ONYU was an app for recording your hikes. Now, we are taking a step further—into a trail community where you can read, participate, and walk together.
■ Guidebook — Courses provided by ONYU in your hands
We have organized and included representative trails, such as the Baekdudaegan and the 100 Famous Mountains, by course based on public hiking trail data. If you download a course you like and save it to your personal guidebook, the map and route will open exactly as they are, even in the mountains where there is no signal. We are also adding official courses recorded by the ONYU team while walking them ourselves.
The guidebook is not a book to read alone, but a map to fill together. We share waypoints for each course and provide the latest updates through comments and photos.
■ Features that are truly useful in the mountains
· Follow Course — As you walk along a saved course, the map tells you where you are and where the trail branches off.
· Remaining Distance and Estimated Arrival Time — It calculates how much distance remains to your destination based on your recent pace. · Sectional Elevation Graph — You can see in advance where the uphill sections begin.
· Offline GPS Recording — It is safely saved even without a signal or when the app is turned off.
■ For Those Worried About My Whereabouts
· Check-in — Let your friends know, "I'm starting right here."
· Location Sharing — Send your current coordinates via Kakao Map or Google Maps link. You can also send them via text message or KakaoTalk to family members who do not use Onyu.
· Real-time Track — You can keep your movements visible in real-time while hiking.
Even if you walk alone, someone knows. Safety comes before functionality.
■ A Character That Grows as You Walk
Experience points accumulate and your level rises as you walk. New characters and titles unlock, and your footprints are displayed through six stats: distance, elevation, frequency, and speed. The criteria vary by activity type, ensuring fairness for everyone.
■ Events and Activities
Attend events using a participation code, walk connected courses, and even receive completion certification. The organizers monitor participants' progress via a status board to ensure safety.
■ Magazines, News, and Weather Alerts
Discover reading material categorized by trail, equipment, and course guides. The app automatically displays weather alerts from the Korea Meteorological Administration—allowing you to check in advance whether it is safe to hike today.
■ Show Off Your Walk
Once your hike is over, we create a card containing your route and records. You can upload it directly to Instagram or KakaoTalk, or export it as a GPX file for safekeeping.
