Ollaga (올라가) is a hiking tracker built for Korea's mountains.
It guides you only on official Korea National Park Service and Korea Forest Service trails, and shows mountain weather and trail closures before you go.
Record your hike by GPS to the summit, then replay it on satellite imagery and 3D terrain.

Ratings & Reviews
This app hasn’t received enough ratings or reviews to display an overview.
More accurate records and a cleaner look.
• Me: a 12-week distance chart on the «This week» card
• Notifications: sender photo and name, grouped into Today, This week and Earlier
• Fixed activity dates and week boundaries shifting with the device time zone
• The post-save summary now separates moving time and total time
• Fixed the 100 Mountains list showing only its first row, meetup times shifting by 9 hours, and the meetup Edit button not responding
• Split gain without elevation data shows as unknown, not +0
• Leftover Korean text removed from English and other language screens
