Get Travelling old version APK for Android
Convenient tool for collecting countries you have visited.
The best way to motivate yourself to visit all countries in the world is to make a list of them and cross out one by one until you visit all of them. For the sake of convenience, I have made a simple app for that.
The idea of this app is not unique, but it is special in its simplicity and absence of useless functionality.
Enjoy Travelling.
