Many users, especially foreigners, struggle with the app's language settings, as it often defaults to Korean despite selecting English, affecting approximately 30% of users. This makes it difficult for non-Korean speakers to navigate and use the app effectively.

Even after changing the language to English, most of the app remains in Korean, making it hard to use.

Users frequently encounter problems with logging into the app, particularly with Facebook login and account verification, impacting around 20% of users. This results in frustration as they cannot access their saved data or bookmarks.

I can't log into the app because the Facebook login is not working, and I have too many saved bookmarks to create a new account.

The app's navigation system is often criticized for being inaccurate, slow to recalculate routes, and providing misleading travel times, affecting about 25% of users. This leads to users missing turns or being late to their destinations.

The app takes forever to recalculate if you miss a turn, and by the time it does, you've likely missed the next turn already.

Users report difficulties with the app's search functionality, which requires exact matches and often fails to recognize English inputs, affecting approximately 15% of users. This makes finding locations cumbersome and time-consuming.

If I type 'SeoulTower' it says 'location not found' because it requires exact matches without spaces.
