The different colors tell you whether I've visited a country.

I haven't visited it.
I've visited it.
I've visited it, and if you click on it, you can see which regions I've visited. If you click again, you will be back to the country view.

There are numerous apps available for tracking the countries someone has visited, but none quite met my needs. That's why I created CountryMappR. Feel free to use it and adapt it for your own needs.

If you have any questions or comments, feel free to reach out to me. My contact details are available on my website.
