The Classic Maya calendar you can audit.
Long Count, Tzolk’in, and Haab’ on your iPhone. Today’s count meets your birth Day Sign. Not a horoscope show.
MayanChart is a Classic Maya day-keep companion. Home is today’s count meeting the chart from your birth date — check-in, calendar strip, one kin-grounded action, optional reflection, and a reading streak. Chart Facts are the numbers you can read back. Ask stays grounded in that count. Optional Apple Intelligence explains computed facts when available, with an on-device knowledge fallback when it isn’t. AI never invents a Long Count, Day Sign, Haab’ date, or Night Lord that isn’t in the engine.
Birth time and place are optional and never change the count — they only refine optional Sky & Timing context.
DAY-KEEP
• Today’s Tzolk’in meeting your birth Day Sign — glyph, calendar strip, alignment
• Check-in, one kin-grounded action, optional reflection
• A reading streak from completed readings — a rhythm, not a scoreboard
• Home Screen and Lock Screen widgets for today’s sign
CHART & ENGINE
• Birth-date math you can read back: Long Count, Tzolk’in (Day Sign + Tone), Haab’, Calendar Round day name, Night Lord (Lord of the Night), Week Bearer, Year Bearer, and the 819-day Kʼawiil station
• Learn — Calendar Cycles, directions and colors, living returns (260-day Tzolk’in return, Haab’ anniversary, ~52-year Calendar Round return)
• Optional Sky & Timing when you add birth time — day-part; deeper moon and sunrise/sunset with Pro — never an input to the count
ASK & READINGS
• Ask questions grounded in your computed chart — a daily taste included
• Day Sign identity and a reading preview to start
• Pro keeps the rest of the memory: remaining pillars, unlimited Ask, History, compatibility, forecasts, Insights, and Chart PDF
• Optional private iCloud so Pro work can follow you — not a MayanChart server account
PRIVATE BY DESIGN
Chart math stays on your iPhone. Local-first by default.
