Free birth chart app: the best free options in 2026

What a free birth chart should include

A complete natal chart places the Sun, Moon and planets in signs and houses, shows your rising sign and midheaven, and lists the aspects between planets. If a free tool only gives you three signs, it is a teaser, not a chart.

The birth time is what makes it personal. Your rising sign changes roughly every two hours, and house placements depend on it. If you do not know your time, a good tool will tell you which parts of the chart are uncertain rather than guessing quietly.

Check the calculation source. Astro.com uses the Swiss Ephemeris, the industry-standard engine. Co-Star uses NASA JPL data. Most apps do not state their ephemeris or house system publicly, which is not necessarily a problem but is worth knowing.

Finally, check what free means. Some tools are free with no account. Some are free inside an app that later asks you to subscribe. Some show the chart free but put the interpretation behind a paywall.

The best free birth chart options, ranked

1. Astro.com — best free deep chart tool. It offers a full natal chart, an extended chart selection with many house systems including Placidus, Koch and Equal, current transits and synastry tools, all free, in 12 languages. The interface is dated and built for practitioners, and the free tier shows ads unless you pay for the 12.90-a-year Plus tier.

2. Cafe Astrology — best free reading library. It has a free natal chart calculator and report with no account needed, free numerology reports, compatibility tools and a deep library of articles on aspects, houses and transits, free since 2002. It is English only, web only and text heavy, and the house system used by the calculator is not stated.

3. Co-Star — best free chart inside a popular app. The free tier includes your full natal chart, daily notifications and basic friend compatibility. It is English only, and 2026 reviews report more features moving behind the Pro-Star paywall.

4. TimePassages — best free chart for technical users. The free mobile account includes one full chart, current transits, a personal dashboard and saved profiles, with six house systems available. Extra charts cost $0.99 each, or upgrade to Mobile Pro.

How to read your free chart once you have it

Start with three placements: your Sun sign, your Moon sign and your rising sign. The Sun describes your core identity, the Moon your emotional needs and the rising sign the way you meet the world. Most people find the Moon and rising more surprising than the Sun sign they already knew.

Next, look at houses. Each house is an area of life — the second for money and resources, the seventh for partnerships, the tenth for career and reputation. A planet's house tells you where its energy shows up. Your house system affects these placements, which is why tools that state theirs are easier to trust.

Then look at aspects, the angles between planets. Conjunctions, trines and sextiles tend to describe ease or blending; squares and oppositions describe tension that pushes you to act. A free chart from Astro.com lists these in a grid; Cafe Astrology explains each one in plain language.

Finally, compare it with today's sky. Transits are the current positions of the planets measured against your chart, and they are what daily chart-based apps read. Astro.com shows current transits for free. If you find yourself checking them every day, that is the point at which a paid daily app starts to earn its price — and not before.

Other free tiers worth trying

5. Sanctuary — its free app tier includes full birth chart details, daily transits, moon cycles and an article library. The web version is limited to daily horoscopes. Its paid side is live readings by the minute.

6. The Pattern — its free personality profile and basic compatibility are substantial and built from your chart, though the app deliberately avoids traditional astrology terms. If you want to see degrees and aspects, it is not the right tool.

7. Nebula — offers a free natal chart analysis and daily horoscope, with tarot, numerology and palmistry at a basic level. Its paid tiers and live advisors are where reviewers report an aggressive funnel.

Free tiers that are thinner: CHANI's free tier gives a basic chart overview and works more like a trial, Moonly charges $14.99 to unlock the birth chart on top of a subscription, and Hint gates most features behind a $1 trial that converts to $29.99 a month.

Where Nuvastro fits, honestly

Nuvastro is not a free birth chart app. It offers a 7-day free trial without a card, and after that a subscription is needed. If you only want to see your chart once, Astro.com or Cafe Astrology will serve you better at no cost.

What Nuvastro adds is ongoing use of the chart. It calculates your natal chart with Placidus houses and aspects from an astronomical ephemeris, falls back to whole-sign houses when your birth time is unknown, and turns that chart into a daily personal reading, alongside a numerology profile and a moon calendar.

It runs as a web app that works on phones and is available in nine languages. It has no live readers and no AI chat, and it does not offer the long list of house systems Astro.com and TimePassages do.

If you want to try it, the trial costs nothing and does not take a card, so there is nothing to cancel if you walk away. If you decide it is not for you, Astro.com remains the free tool we would recommend, with Cafe Astrology alongside it for interpretation.

What upgrades cost, as of October 2026

Astro.com Plus is 12.90 USD or EUR a year and mainly removes ads. Cafe Astrology sells optional one-time reports, with prices not stated publicly on the pages we reviewed.

Co-Star Pro-Star is $8.99 to $9.99 a month. TimePassages Mobile Pro is $7.99 a month or $59.99 a year. The Pattern Go Deeper+ is $14.99 a month.

Nuvastro is $9.99 a month, $39.99 for six months or $74.99 a year after the 7-day free trial, with local prices in 11 currencies. Moonly's birth chart add-on is $14.99 on top of its subscription.

Nebula and Sanctuary charge separately for live readings, from $2.99 to $19.99 a minute depending on the reader. None of these upgrades is needed simply to see your chart; they pay for interpretation, daily use or a person to talk to.

Which free option suits you

Use Astro.com if you want the most accurate free chart and the option to change house systems. Use Cafe Astrology if you want to read clear, free interpretations of each placement.

Use Co-Star if you want a free chart in a phone app that friends already use. Use TimePassages if you want a free chart app with serious technical settings, with whole-sign and Placidus among its selectable house systems.

Use The Pattern if astrology vocabulary puts you off and you want the chart translated into personality language. Its free tier is generous enough that many people never upgrade.

Use a paid app, including Nuvastro, only if you want the chart turned into something you return to daily. Before paying for anything, generate your chart on two free tools and compare them. If the rising sign or house placements differ, the cause is almost always the birth time or time zone, and it is worth fixing before you build any habit on top of the chart.

Common questions

Where can I get my full birth chart for free?

Astro.com and Cafe Astrology both give a full natal chart for free on the web. Co-Star, Sanctuary and TimePassages include a full chart in their free app tiers.

Is Astro.com really free?

Yes. Chart calculation, many house systems and transit tools are free. The optional Astrodienst Plus tier, 12.90 USD or EUR a year, mainly removes ads.

Can I get a birth chart without my birth time?

Which free birth chart app is most accurate?

Astro.com uses the Swiss Ephemeris, the standard engine for astrology software. For any tool, the biggest accuracy factor is an exact birth time and correct birth place.
