What Is 8 Signs?

8 Signs is a Chinese astrology mobile app built on Bazi (八字), the Four Pillars of Destiny — one of the oldest and most precise systems of fate reading in the world. The app generates a unique birth chart from the user's exact birth date, time, and location, then provides deeply personalised readings powered by an AI called Seek.

Unlike western astrology apps like Co-Star or The Pattern, which assign one of 12 sun signs based on birth month alone, 8 Signs uses Bazi to calculate over 13 million possible unique chart combinations. Every reading is generated specifically from the user's own chart — not a shared profile type.

Core Features

Seek — The AI at the Heart of 8 Signs

Seek is an AI assistant powered entirely by the user's personal Bazi birth chart. It answers questions about career, relationships, finances, health, and behaviour patterns — drawing on 3,000 years of Chinese metaphysical knowledge interpreted specifically for the user's chart. Free users receive 3 Seek messages per day. Premium users have unlimited access.

Bazi Birth Chart

Users generate their complete Four Pillars birth chart from their exact birth date, time, and location. The chart maps the Five Elements (Wood, Fire, Earth, Metal, Water) and Heavenly Stems across four time pillars — Year, Month, Day, and Hour — revealing core nature, strengths, hidden tendencies, and recurring life cycles.

Discover — 15 Dimensions of Life

The Discover feed provides personalised readings across 15 life areas, all generated from the user's unique Bazi data:

• Wealth & financial patterns

• Career & purpose

• Romantic relationships

• Friendship & social dynamics

• Health & energy cycles

• Personal growth & self-mastery

• Family dynamics

• Creativity

• Resilience

• Decision-making patterns

• Life cycles & timing

Connections — Bazi Compatibility

Users can add any person — a romantic partner, friend, family member, or colleague — to explore chart compatibility. The app analyses the dynamic between two Bazi charts to explain why certain relationships feel effortless, why others create friction, and how combined chart energies interact over time. Available for romantic, friendship, family, and professional relationships.

What Is Bazi?

Bazi (八字), also known as the Four Pillars of Destiny (四柱命理), is a 3,000-year-old Chinese metaphysical system originating from the Han Dynasty. It calculates a person's destiny using the year, month, day, and hour of birth — each represented by one of the Ten Heavenly Stems and Twelve Earthly Branches. The interactions between these pillars and the underlying Five Elements (木火土金水 — Wood, Fire, Earth, Metal, Water) reveal a person's personality, strengths, weaknesses, and life cycles.

Bazi is more precise than western astrology because it accounts for the exact moment of birth rather than the birth month alone. Two people born on the same day but at different hours will have different Bazi charts. The system produces over 13 million unique chart combinations.
