Nuvastro vs Astro.com: an honest comparison

Quick verdict: who each one is for

Astro.com, run by Astrodienst, is for people who want to calculate charts accurately and study them. It is free, it uses the Swiss Ephemeris, and it lets you choose between many house systems, draw relationship charts and look at transits. Practising astrologers around the world rely on it, and nothing in the consumer app market matches the breadth of its toolset.

Nuvastro is for people who want to know what their chart means for today, without building the interpretation themselves. It turns your natal chart and the current transits into a daily written reading, adds a numerology profile and a moon calendar, and sends the reading by email. It is a paid product with a 7-day trial that needs no card.

These are not really competitors. Astro.com is the best free place to check your chart; Nuvastro is a place to read about your day. If you only need the chart, Astro.com is the obvious choice and costs nothing.

If you want daily interpretation and are happy to pay for it, Nuvastro does work that Astro.com deliberately does not try to do.

How the readings are made

Astro.com calculates. It shows you positions, houses, aspects and transits, along with horoscope content and interpretive text for some chart types. It has no app or push notifications; you visit the site and look up what you need. Paid horoscope subscriptions exist, but the free site does not send a daily personal reading. That suits people who enjoy reading charts directly.

Nuvastro calculates and then writes. It computes planetary positions from an astronomical ephemeris, compares the day's transits with your natal chart, and produces a daily reading that names the house and aspect behind each point. Simple mode gives a short plain-language version; advanced mode shows placements and degrees.

So the choice is about where the interpretation happens. With Astro.com, you do most of it, which is ideal if you are learning or already know astrology. With Nuvastro, the reading arrives already interpreted, which is faster but leaves fewer choices in your hands.

Neither product has an AI chat or live readers. If you want to ask a question about your chart and get an answer, you will need a human astrologer outside both products. Neither one is set up for conversation, and that is by design rather than an oversight.

Natal chart, houses and accuracy

Astro.com has the strongest accuracy credentials of any product in our comparison set. It uses the Swiss Ephemeris, the industry-standard calculation engine, covers a range of thousands of years, and supports Placidus, Koch, Equal, Carter poli-equatorial and other house systems through its Extended Chart Selection. If you want to compare house systems, it is the place to do it.

Nuvastro uses Placidus houses with a known birth time and whole-sign houses when the time is unknown. You cannot switch house systems, which is a real limitation for experienced astrologers. If you prefer Koch, Equal or whole-sign houses with a known birth time, Nuvastro will not accommodate that. In return, the reading is always consistent with one clearly stated method.

For your planets' signs and degrees, Nuvastro and Astro.com should agree closely, because both work from astronomical ephemeris data. If you see a difference in houses, check that you have selected Placidus on Astro.com and that you entered the same birth time and place in both.

If you are serious about technique, Astro.com is the better calculation tool, full stop. Nuvastro's case is not more precision but less effort.

Numerology and the moon calendar

Astro.com does not offer numerology. Nuvastro includes a full numerology profile: life path, expression, soul urge, personality and birthday numbers, plus personal year, month and day numbers that sit beside the daily reading.

A dedicated moon calendar is not confirmed as a distinct Astro.com feature, although its ephemeris and horoscope tools show lunar positions, and an experienced user can work out the moon's sign and aspects for any date.

Nuvastro's moon calendar does that work for you: it shows the moon sign for each day, void-of-course periods and days that suit particular kinds of tasks, all at a glance. For people who plan around the moon but do not want to read an ephemeris, that is the clearest practical difference.

If you enjoy reading an ephemeris yourself, you may not need Nuvastro's calendar at all. But if you want a quick answer to whether today is a good day to sign something or start a project, a calendar you can scan in seconds is easier than reading positions and timing ingresses by hand.

Price and trial, as of October 2026

Astro.com's core service is free: full natal charts, extended chart options, transits, an ephemeris spanning thousands of years and horoscope content. The free site shows ads. Astrodienst Plus costs USD/EUR 12.90 per year, about $1.08 per month, and mainly removes ads. No trial applies because the core is already free.

Nuvastro costs $9.99 per month, $39.99 for six months or $74.99 per year, with local prices in 11 currencies. The 7-day trial includes everything and needs no card.

On price alone, Astro.com wins easily. You are paying Nuvastro for interpretation, daily delivery, numerology and the moon calendar, not for the chart itself. If those do not matter to you, there is no reason to pay.

Trustpilot reviewers have complained about ads on the free tier, which the Plus plan addresses for a small yearly fee. Nuvastro shows no ads at all, but it is a paid product after the trial, with only guides and tools on the site free beyond that.

Where each one clearly wins

Astro.com wins on calculation depth, choice of house systems, synastry and relationship charts, reference tools such as Astrodatabank, price and track record. It is also available in 12 languages, including German, French, Italian, Russian, Dutch, Danish and Portuguese, which Nuvastro does not support.

Nuvastro wins on daily interpretation, a modern interface built for phones, a daily reading email, numerology and a moon calendar with void-of-course periods. It also supports Korean, Georgian, Arabic, Hebrew and Traditional Chinese, which are not among Astro.com's confirmed languages.

Reviewers describe Astro.com's interface as dated and built for practitioners rather than casual daily users. That is fair, but it is also why practitioners trust it. Nuvastro is easier to read on a phone, but it offers far fewer options.

Daily habit is where Nuvastro is most different. Astro.com has no app or push notifications and no simple mode. It is built for looking things up, not for a daily habit. Nuvastro was built around that habit: one reading each morning, in your inbox or in the web app, with the moon and your personal day number next to it.

Switching, using both, and the verdict

Most people do not need to switch. Keep Astro.com bookmarked for chart calculation, house-system comparisons and relationship charts. Use Nuvastro for the daily reading, numerology and moon calendar. Entering your birth data in both takes a minute. Because Nuvastro uses Placidus by default, set Astro.com to Placidus too when you compare, and the houses should line up.

If the two ever disagree, treat Astro.com as the calculation reference and check your settings. The usual causes are a different house system, a different birth time or a different birthplace.

The verdict: Astro.com is the best free tool for anyone who wants to calculate and study charts. Nuvastro is for people who want their chart read for them every day, with numbers and moon timing alongside. If you already love Astro.com, try the Nuvastro trial to see whether daily interpretation is worth paying for.

If you never want to pay for astrology, stay with Astro.com. That is a perfectly good choice.

Common questions

Is Astro.com accurate?

Yes. Astro.com uses the Swiss Ephemeris, the industry-standard calculation engine, and is widely used by practising astrologers.

Is Astro.com free?

The core service is free with ads. As of October 2026, Astrodienst Plus costs USD/EUR 12.90 per year and mainly removes ads.

Does Astro.com give daily horoscopes for my chart?

Astro.com shows your transits and offers horoscope content, but it is a calculation and reference tool rather than a daily-reading product. Nuvastro writes a daily reading from your chart and sends it by email.

Can I change the house system in Nuvastro?

No. Nuvastro uses Placidus with a known birth time and whole-sign houses without one. Astro.com lets you choose from many house systems.

Why do my houses differ between Astro.com and Nuvastro?

Check that Astro.com is set to Placidus and that you entered the same birth time and place. If your birth time is unknown, Nuvastro uses whole-sign houses.
