Cooljam Tour

Korean Guide of Europe

Cooljam Tour is another one of our interesting projects: it is an audio guide of European cities intended specifically for South Koreans. We have found that South Koreans prefer using travel guide products from home, ignoring Lonely Planet and other guidebooks. Fortunately, our app came in to save the day, and many South Korean travelers have been utilizing it on their journeys!

Our solution

The main requirement of our client was that the app should work seamlessly in offline mode. In addition to making this possible, we also created a backend application that makes it easy to add audio guides for new cities.

Main benefit

At Ackee we are pleased that our application helps South Koreans discover the beauty of European cities.

Our application aims at Asian markets where a different set of game rules are still applied. Ackee faced this challenge without fear and managed to complete the task professionally and at a high level.
