Most matching apps hand you a number with nothing behind it. Kaal scores the same classical systems an astrologer uses, then shows the reason for every point so you can read it yourself.
Both birth charts are computed on Swiss Ephemeris with the True Pushya Paksha ayanamsha — the identical engine behind every Kaal reading. Signs, nakshatras and ascendants are sidereal and consistent across the whole product. A birth time sharpens the Moon and ascendant layer; leaving it blank assumes noon, which we mark on the report.
The eight kootas are the recognised Guna Milan, scored from each person's Moon sign and nakshatra, out of 36:
We show each koota's points and the reason, not just the total — including the Nadi exception when it applies.
The Ashtakoota 36 is necessary but not sufficient — low-score couples are often happy and high-score ones are not. So on top of it we score four chart-grounded layers, out of 64, for a 100-point read:
The card does not lead with a bare number. The same 100 points are re-expressed as the five areas a relationship is actually lived in, so each one is the classical score read back in plain terms:
The five sum back to the same 100, so nothing is added or hidden between the score and the areas. Romance and the closing read are grounded further in the classical houses of love, the fifth for romance and the eighth for depth and intimacy, translated to plain feeling.
Mars is checked from three reference points — the ascendant, the Moon and Venus — with the classical cancellations (Mars in its own or exalted sign, the sign exceptions, a Jupiter aspect). When both charts carry the factor it is mutually neutralised. We frame a Mangal factor as an area to handle with awareness, never as a barrier to marriage.
Beyond the score, the report surfaces the chart-grounded specifics most apps never compute: the likely temperament and rising sign of the partner, the direction they tend to come from, the Darakaraka (the chart's own spouse-significator), the Upapada that grades the marriage's durability, and the relationship yoga between the two charts.
The match-making model follows the classical texts and modern research that codify them: Basistha Tiwari's 100-point system, KN Rao on marriage timing, C.S. Patel on the navamsa, the Stree Jataka compilation on the seventh house, and Prabhakara Murthy on the Jaimini karakas. Every rule traces to a source rather than a house style.
A score is guidance, not a verdict. We lead with the strengths and name the lower areas as places to navigate with care, never as "do not marry". Every point traces to a classical rule and a chart fact, so the reading can be checked rather than taken on faith.
