A clear guide to choosing a kundli matching app: what Guna Milan checks, which features matter, and honest limits of the score.
A practical guide to what kundli matching actually measures, how apps differ, and what the score can't tell you.
There is no single 'best' kundli matching app for everyone — it depends on whether you want a free instant Ashtakoot Guna Milan score, a live astrologer's interpretation, or a tool that discloses its calculation method so you can check it. This guide lays out the selection criteria, what each app category actually offers, and where the score's real limits are — so you can judge apps on facts rather than star ratings.

Kundli matching, also called Guna Milan, is a traditional Vedic astrology method that compares two people's birth charts — mainly the Moon's position — across eight categories (kootas) to produce a compatibility score out of 36. It is a cultural and astrological practice used before marriage in many Indian households, not a scientific test of relationship success.
Apps calculate Guna Milan by first building each person's birth chart from date, time and place of birth, then locating the Moon's sidereal position (its nakshatra and sign) for both people, and finally comparing those positions against fixed Ashtakoot rules to award points in each of the eight kootas. The sidereal calculation requires an ayanamsa — a correction that adjusts the tropical zodiac to the star-based one. Lahiri is a commonly used ayanamsa in Indian astrology and is associated with India's national calendar tradition, but apps may use different settings, and results can shift slightly depending on which ayanamsa and ephemeris an app applies. When comparing apps, check whether the ayanamsa and ephemeris source are disclosed anywhere in their documentation — a listing alone may not explain every calculation setting.
The Ashtakoot system scores eight categories that together add up to 36 points. This scheme, and the specific weight given to each koota, is described in classical Vedic astrology texts, though exact rules and emphasis can vary between regional traditions and individual astrologers.
This example uses AskSoma's implemented scoring rules with supplied Moon placements: person A has Ashwini in Aries (nakshatra 1, sign 1), and person B has Mrigashira in Gemini (nakshatra 5, sign 3). The rule entries and arithmetic are shown below. These are synthetic inputs, not positions derived from birth records. No Mars position or ascendant is supplied, so the example makes no Manglik assessment.
A transparent kundli matching tool should return more than a single number. At minimum, look for: the individual koota-by-koota breakdown (not just a total), the total out of 36, which ayanamsa and ephemeris were used, and whether dosha checks (like Mangal or Nadi dosha) were run and on what basis. If an app only shows a final score with no breakdown or method disclosure, you cannot fully reproduce or assess the result.

Choose the feature you need before comparing brands. Someone who wants to inspect chart settings has a different requirement from someone who wants to discuss a report with an astrologer. The official-source comparison later in this guide explains what AstroSage and Astroyogi advertise, along with the limits of those descriptions.
A star rating is a broad impression of an app, not a test of its matching calculation. Read recent reviews for specific issues that affect your use, such as unreadable reports or difficulty cancelling a purchase. If a review concerns a different phone platform or an old release, check whether it still applies.
A Guna Milan score, no matter how it's calculated, is not a certainty of marital happiness or compatibility. It is a traditional screening tool, and a high score does not guarantee a good relationship, nor does a lower score guarantee a bad one. It also cannot substitute for actual conversations about values, consent, finances, or life goals between two people.
Exact birth time matters most when the Moon is near the boundary between two nakshatras or two signs at the time of birth — in that case, a few minutes' difference can shift which nakshatra or sign is used, which affects Tara, Yoni, Gana, and Nadi. Bhakoot is based on the relationship between the two Moon signs rather than a finer time-based subdivision, so it is less sensitive to small time errors than nakshatra-based kootas, but it can still change if the birth time error is large enough to shift the Moon into a different sign entirely. If your birth time is unknown or approximate, ask any tool you use to flag which kootas are uncertain rather than presenting a single confident number.
Start with the [kundli matching tool](/kundli-matching) to see the score breakdown. If you choose an additional report or consultation on any service, check what the displayed price covers before continuing: one report, a timed conversation or recurring access. The official product descriptions linked below distinguish free chart/report offers from additional services without treating one offer as a promise that everything is free.
Matching two charts on AskSoma takes three steps: enter both people's birth details, review the koota-by-koota breakdown, and optionally continue into a deeper reading.
For chart settings and language choices, AstroSage is worth shortlisting; for a matching report followed by an astrologer conversation, consider Astroyogi. These recommendations are based on documented features, not an accuracy ranking or a hands-on test. AskSoma publishes this guide, so its own calculator is an interested-party option rather than an independent winner.
Method: this comparison uses the linked vendors' product descriptions and AskSoma's scoring implementation. Features and prices may change. It is not a hands-on test of the mobile apps, their accuracy or their privacy controls.
The right choice depends on whether you want chart settings, a free report, a practitioner conversation or particular privacy controls. The source-based comparison above explains those tradeoffs. Ratings and download figures are platform-specific and can change; check their source and date rather than treating them as proof of quality.
No — kundli matching is a traditional astrological practice, not a scientifically validated method. The score should not be used as proof that a marriage will succeed, so treat any score as a cultural and traditional reference point, not a scientific prediction.
18 out of 36 is a commonly used modern rule of thumb, but thresholds and the importance assigned to individual kootas vary among practitioners and traditions. It is not a scientifically validated cutoff, and some astrologers weigh specific doshas (like Nadi) more heavily than the raw total.
No single score can predict a happy marriage. Kundli matching is a traditional screening step that many families use alongside — not instead of — direct conversation, shared values, and mutual consent.
Some apps offer a free score; AstroSage states it offers free kundli creation on its own site, and Astroyogi states it offers a free matching report alongside paid astrologer consultations, per their own pages. On AskSoma, the koota-by-koota Guna Milan score is free through the [kundli-calculator](/kundli-calculator) tool; we have not independently verified other vendors' current pricing.
Some results may be estimated if the Moon remains in the same relevant sign or nakshatra throughout the possible time window, but a good tool should clearly flag this uncertainty rather than presenting an estimated score as fully reliable. If birth time is completely unknown, treat any Nadi or Tara result with caution.
Nadi dosha is a traditional astrological classification based on both partners sharing the same Nadi group; it is not evidence of genetic or medical compatibility. Cancellation rules for Nadi dosha differ between astrological schools, so whether it's considered 'cancelled' in a given chart depends on which tradition or astrologer's rules are applied.
Date, time and place help calculate each person's Moon sign and nakshatra accurately. Exact time matters especially near a sign or nakshatra boundary. If time is unknown, a tool should check the possible range and explain any uncertainty instead of treating one assumed time as confirmed. Broader chart interpretation may require information beyond the Moon sign and nakshatra.
