Swiss-ephemeris precision·Free plan, no card·Cancel anytime
Most people know their Sun sign and nothing else. Your chart holds ten planets, twelve houses and dozens of aspects - a precise picture of your strengths, your recurring tensions and the direction they’ve always pointed. Seeing it drawn is the first step to trusting it.
A hard year is easier to carry when you know what it’s for and when it lifts. Transits show which planet is pressing on which part of your chart, what that season tends to teach, and the dates it eases. Pressure becomes a passage instead of a verdict.
Attraction is easy to feel and hard to explain. Partner Astro lays one chart over the other: where your Moons understand each other, where Venus and Mars pull, where Saturn asks for patience, and which of your houses the other person lights up. The partnership analysis names what draws you together, where friction comes from, and what the two of you are built for.
Move your birth chart across the map and the angles shift - a different planet rises, a different one culminates. Astrocartography draws those lines over the world so you can see where the Sun steadies you, where Venus warms relationships, where Jupiter opens doors. Choosing a city, a move or a second home stops being a guess and becomes a reading.
Insight becomes potential when it changes what you do on Tuesday. Time a launch, a conversation, a move or a rest with the transits ahead. Return to the chart when you drift. Living to your fullest isn’t a mood - it’s a practice, and natalGPS is the instrument.
Planets, houses, and aspects computed from your exact birth time and place. Written reports on identity, relationships, career, money and health translate the geometry into plain language you can act on.
A bi-wheel puts the moving planets around your natal chart for any date you pick. A transit window lists every exact contact ahead, to the minute, and a written forecast turns the season into themes and timing.
Planetary lines drawn on a detailed world map show where each planet rose, set or culminated at your birth. Click any place for its relocated chart and the local-space directions from where you stand.
Synastry lays one chart around the other: the cross-aspects between you, whose planets fall in whose houses, and a partnership analysis for the topics you choose.
Every position comes from the Swiss Ephemeris, the engine professional astrology software relies on, with historical time-zone rules applied to your birth time and the exact UTC instant shown beside each chart.
Natal chart, transits, astrocartography and synastry all read the same birth data, so the map, the forecast and the partner comparison agree with each other to the minute.
Reports and forecasts are generated from your actual placements and dated transits, framed as reflection rather than prediction, and available as PDF on the Astrologer plan.
Every function reads the same birth data, so nothing has to be entered twice and every reading builds on the last.
Ten planets, angles, houses in six systems and every major aspect, calculated with the Swiss Ephemeris and historical time zones.
Written readings of your own chart for General, Relationship, Career, Money and Health - not sun-sign boilerplate.
The sky over your chart for any date, plus written forecasts for today, this week, this month, this quarter or the year.
Every exact contact, sign change, station and lunation in the period you choose, timed to the minute.
Your transit report written and sent to you as a PDF - daily, weekly, monthly, quarterly or yearly.
Your planetary lines, aspect lines and parans on a real world map; click any place to read its relocated chart.
Cities ranked for love, career, money, health or home by how your lines run through them.
A written reading of any city: which lines shape it, what the relocated angles say, which directions to face.
Two charts laid over each other: cross-aspects, house overlays and a written partnership analysis by topic.
The chart of each birthday year, cast for any place, plus secondary progressions and solar arc directions.
27 asteroids on every wheel, and a plain-language explanation for every planet, sign, house and aspect on hover.

It uses the same ephemeris. Planetary positions are precise to fractions of an arc second, six house systems are available, and exact transit times are refined on the ephemeris to the minute.
For houses, the Ascendant and astrocartography lines, yes; four minutes shift the Ascendant by about a degree. Without a time, natalGPS still calculates the planets for noon and leaves houses out rather than guessing.
Yes. Each chart is a profile in your account, and Partner Astro compares any two of them. Enter other people’s birth data only with their agreement.
