imotionengine · Compatibility
Stress test your chemistry
with others.
Enter birth data and compare compatibility using five ancient systems, modern biorhythm science, and Zumi, the archetype system. Each returns their own verdict. We combine them into one overall score. Nothing softened. No sign-up.
Inside the seven readings
Each one looks at the same charts through a different lens. The overall score is what survives all seven.

The synthesis of the other six
Zumi Archetype
What the other six readings agree on when you crystallise them.
Zumi takes the outputs of the six readings above (planets, Nakshatras, pillars, Tzolkin, life-path, biorhythm) and resolves them into nine cross-engine nodes. Each person lands as one of seven archetypes: Sovereign, Architect, Beacon, Resonator, Navigator, Catalyst, Mirror. That gives 28 unique pair-keys, each with twenty test-audience calibrated paragraphs.

Each birth date opens a chart. Add times, timezones, places, and names if you have them, the readings sharpen with each one. Skip what you do not.
How each reading sees the chemistry
Every other app shows you a single reading. One tradition speaks, nobody fact-checks it, and you walk away hearing whatever flatters or frightens you most. imotionengine runs all seven against the same birth data at the same time. A high Western score that the Vedic side flatly disagrees with shows up as real friction, not a polished 92 percent. The overall fit is the weighted average across all seven. A single-engine misread has nowhere to hide.
Western synastry
True Placidus houses. Sun, Moon, Venus, Mars aspects with orb-tightness weighting. The extension layers most apps skip: Chiron synastry (where one person activates another's wound), Lunar Nodes (karmic axis pulls), Vertex contacts (the relationship's appointment), and full house overlays in every direction (each person's planets in everyone else's houses). Tightest contacts surface as named patterns, not generic placeholders.
Vedic Kundli Milan
The full 36-guna Ashtakoot match across all eight kootas. Sidereal Lahiri ayanamsa. Manglik dosha with the four classical cancellation rules, including the cross-chart check. Nakshatra pada compatibility. Spouse Palace (7th-lord dignity), Dasha Sandhi windows when one person's period is winding down, and the Navamsha D-9 overlay when birth times are present.
Chinese BaZi (Four Pillars)
Full Four-Pillars compute with the Li Chun year boundary, not Chinese New Year. Year, Month, Day, Hour pillar interactions. Day Master compatibility on a 100-pair table with the Wu Xing generating and controlling cycles. Stem Combinations (天干合), Spouse Palace 六冲 clashes, secret friend (六合) and affinity triangles (三合) all surface when they fire.
Mayan Day-signs
The 260-day Tzolkin cycle paired with the 13-tone wavespell. Relationships classified across seven buckets: same sign, analog ally, antipode (polar opposite), guide, occult relation, family color, and neutral. Tone-pair harmonics layer on top: harmonic resonance, polar pair (sum to 14), family seasons (creative, reflective, self-regulating, transcendent), and the rare same-trecena windows.
Numerology Life Paths
Life Path × Life Path on the canonical 45-pair Pythagorean matrix. When everyone's names are entered, the Expression and Soul Urge layers kick in for a full multi-layer composite. Karmic Debt numbers (13, 14, 16, 19) surface as penalties; Karmic Lesson complementarity (where your missing digit shows up as another person's strength) surfaces as a bonus.
Biorhythm Sync
Physical 23-day, emotional 28-day, intellectual 33-day cycles, plus four extended cycles (intuitive, aesthetic, awareness, spiritual). Mutual critical days for the next two weeks surface as concrete dates, not abstractions. This is the one row on the card that updates daily, so the same chart group re-reading next month gets a fresh biorhythm read while the other six stay locked.
Zumi archetype
Zumi is not a seventh tradition sitting alongside the other six. Zumi is the synthesis OF the other six. The Western planets and aspects, the Vedic Nakshatras and Dasha lord, the Chinese Four-Pillars stem and branch, the Mayan Tzolkin sign and Lord of the Night, your numerology Life Path, Expression, Soul Urge, and Karmic Lessons, your biorhythm composite at birth and across the grand cycle, all feed into one place.
That synthesis resolves into a nine-node profile (Crown, Voice, Heart, Will, Path, Receptive Crown, Receptive Voice, Receptive Heart, Receptive Will), and the dominant pattern across those nine nodes places each person as one of seven archetypes: Sovereign, Architect, Beacon, Resonator, Navigator, Catalyst, Mirror. Compatibility runs across the 28 unique archetype interactions, with twenty test-audience calibrated paragraphs per interaction, surfaced one at a time via a deterministic rotation so everyone reading the same chart group always sees the same paragraph. The score is modulated by shared lit circuits and node bridges across the blueprints. When the other six readings disagree on what the dynamic is, Zumi is the row that tells you what they collectively settle on.
The headline here is free. The paragraph-depth read on each engine, plus the live calibration system that shows which traditions actually predict outcomes for you, sit inside the app. Open the dashboard after running this to go deeper on any single reading.
