KakaoBus is a free Android application that provides real-time bus and bus stop information for 57 Korean cities. With this app, you can get real-time bus arrival information and bus route information with real-time bus location. It also offers a departure alarm that notifies you five minutes, three minutes, or one minute before the bus arrives at your stop. Additionally, you can set an arrival alarm to ensure that you get off at the correct stop.

KakaoBus also offers a bus arrival notification feature, which sends you notifications for buses on specific days and times without having to set them manually every time. Moreover, you can get suggestions based on your current location, including nearby stops, night buses nearby, direct bus to home, and Kakao Taxi. However, it is important to note that continued use of GPS running in the background can dramatically decrease battery life.

KakaoBus requires optional permissions for location to search nearby bus stops and provide arrival alarms using the current location information. It also requires notification permissions to receive alarms with sounds and badges. For customer service, you can contact Kakao Corporation via mail or telephone.

Overall, KakaoBus is an excellent app that provides real-time bus and bus stop information for Korean cities, making it a must-have for anyone who frequently uses public transportation in Korea.
