I’m a medical student from South Korea and a heavy traveler who has been exploring the world almost every month since 2024. After a gap year spent visiting 10 countries in 20 days and 18 countries in a single month—including remote places like the Faroe Islands—I realized that for me, traveling had become a "mission" or a "game."

I wanted an app that could track more than just country counts, such as the combined population of visited areas or specific themes like Muslim-majority countries. When I couldn't find one, I built my own. Despite no prior coding experience, I integrated massive databases of 15,000+ cities and global airports. I manually reviewed over 10,000 entries over three months to ensure accuracy for less famous locations. I finally launched the app this March, and the Android version has already surpassed 20,000 downloads.

As a traveler myself, I am always looking for ways to improve the experience. If there’s anything you’ve always wanted from a travel app, I’d genuinely love to hear it.
