When planning a trip to Korea, knowing the best apps to install on your smartphone is essential to make your stay as smooth and comfortable as possible. Of course, to use them you will need an Internet connection, either by renting a pocket WiFi or purchasing a SIM card.
Few people know that the same apps widely used in Europe or the US are not as common in Korea.
In this article, you will discover the must-have applications for your smartphone when traveling to Korea in 2025, or even if you are relocating to study or work. From transportation to payments and dining, there is literally an app for everything.
The apps I recommend here are the most useful and practical ones, so you don’t have to spend hours researching like I did on my first trip to Korea.
Some are essential for every traveler (Trazy, GetYourGuide, Naver Maps, Seoul Subway, Uber, Papago, and Revolut), while others may be useful depending on the specific services you need. For each recommended app, you’ll find a short description and download links from the Play Store (for Android users) and the App Store (for iPhone users).
Before moving on to communication apps, let’s answer one of the most common questions: Does WhatsApp work in South Korea? The answer is yes. WhatsApp works perfectly in Korea, you just need a data connection via pocket WiFi or a Korean SIM card, exactly as in Europe.
WhatsApp will probably be the app you use the most to text and call your family and friends back home. Regular international phone calls are very expensive, but with WhatsApp everything is included in the data plan you purchased.
After trying the best and most recommended apps for travel to Korea, you’ll be able to move around, communicate, pay, and enjoy your trip much more smoothly. Make sure to install these apps before your departure so you’ll be ready to experience Korea like a local, without unnecessary stress or wasted time.
