In June 2011, we launched "MCP Mayan Tzolk'in," the official mobile app of the Mayan Calendar Portal. Compatible with iPhone 3 and 4, iPod Touch and iPad 1 and 2, as well as the Android platform, the MCP Mayan Tzolkin presents the complete set of 260 daily energies of the Tzolk'in calendar, compiled for the first time according to the tradition of the Maya from the highlands of Guatemala.
The app also features updated descriptions of the daysigns, numbers and deities.
