Among Apple's iTunes, Google Play, and Amazon apps, there are hundreds of thousands of mobile apps out there. 

But there is only one MCP Mayan Tzolk'in, and only one My Mayan Match.

Only two apps that bring you those aspects of the Mayan Calendar that are most relevant to modern life:
how to live with the sacred cycles of the Tzolk'in, and how to determine your personal compatibility with the people in your life. 

And of course they're available for both the iPhone and Android platforms.
