About this app

Sigil Grid is a living almanac — a spiral-geometry calendar that turns time into a visual instrument, and a multi-divination canvas where astrology, sacred grids, tarot and the lunar cycle share one fluid workspace.

At its heart is a novel idea of the calendar: instead of a flat list of days, dates spiral outward from a central point so you can see the angular relationships between them at a glance.

— ASTROLOGY —

A full chart wheel and transit dial, rendered in living geometry:

- Natal wheel + bi-wheel for transits and synastry
- 90° Uranian / Hamburg dial with midpoint trees
- Astrocartography map — planetary lines across the globe
- Aspectarian grid, planetary positions, profections
- Arcane or gold dial styles, elemental tints, Cormorant glyphs
- Scrub time forward and back to watch the sky move

— SACRED GRIDS —

The spiral calendar that names the app:

- Hexagon & Square of 9 spirals with adjustable rings (4–12)
- Cardinal (0/90/180/270) and ordinal (45/135/225/315) cross overlays revealing angular date harmonics
- Place any date at the center; dates on the same angular line are harmonically related
- Perfect-square number markers along the spiral

— THE ALMANAC —

- Moon-phase tracking through the current lunation
- Eclipse tracker for upcoming solar and lunar eclipses
- Solar event markers — solstices and equinoxes
- Date tagging — mark and annotate significant days
- Calendar mode with day/month navigation
- Home-screen widget with the daily grid

— MORE WAYS TO READ —

Beyond astrology and grids, the same canvas hosts Tarot spreads, Human Design bodygraphs and I Ching hexagrams — switch modes and the toolbars adapt to each.

Works fully offline — every calculation runs locally on your device. Optional Telegram login syncs your saved charts, events and tags across devices.

Whether you practice esoteric astrology or simply want a more beautiful way to visualize time, Sigil Grid transforms the calendar from a flat grid into a living geometric structure.
