What if you could track your own patterns — and actually start to see them?
Arka is a self-knowledge and journaling app built on Ba Zi, the Chinese Four Pillars system. Ba Zi uses your exact birth date and time to map your personality, your natural rhythms, and the energetic conditions of each day. It's been used for centuries for decision-making and self-understanding. Arka makes it accessible to anyone — no prior knowledge needed.
JOURNAL YOUR DAYS. SEE YOUR PATTERNS.
Every day, Arka gives you a brief insight drawn from your personal chart. At the end of the day, log how it actually landed — how the day felt, what came up, anything worth remembering. Over time your Journal becomes a personal record of how your chart shows up in your real life. The Trends tab shows your energy patterns across the last 30 days and the areas of life that have been most active.
WHAT'S INSIDE
◆ Journal — log how each day felt and what came up. Review your entries and see your energy trends over 30 days.
◆ Insights — daily, weekly, monthly, and annual chart readings. Built from your personal Ba Zi chart, not a generic sun sign.
◆ Day Master — a detailed personality profile based on the dominant element in your birth chart. One of ten distinct types.
◆ Celestial Collection — daily card drops tied to the Chinese solar calendar. Each card is unique to the current solar term.
◆ Oracle — the I Ching. Cast coins, build your hexagram, receive an interpretation grounded in the Wilhelm translation.
◆ Friends — compare charts with people you know. See how your Day Masters interact.
FOUR PILLARS
Ba Zi is a deterministic system — your chart is calculated from your exact birth date and time. Every reading is built from your personal chart and yours alone. This is a tool for people who want to understand their own patterns.
