AstroPal vs Co-Star: which is better?

Sidereal depth and dasha timing a tropical app cannot reach.

Try AstroPal freePro is ₹501 / month

The short answer

Why AstroPal beats Co-Star.

  • Sidereal Jyotisha, the tradition Co-Star does not work in
  • Dated Vimshottari dasha timing, where Western astrology has none
  • 12 divisional charts and computed planetary strength
  • 11 reports, 4 free forever, saved and exportable, not a daily one-liner

Where Co-Star falls short

  • Tropical zodiac, so it is answering a different question than Vedic astrology
  • No dasha system, so it cannot tell you when anything happens
  • Daily one-liners, with no long-form analysis you can keep

In fairness, what Co-Star does well

  • Genuinely excellent planetary data sourced from NASA
  • Distinctive design and voice that nothing else has matched
  • Friend and partner compatibility handled elegantly

Co-Star is the app that made astrology culturally unavoidable again: stark black-and-white design, NASA-sourced planetary data, blunt daily push notifications, and friend compatibility built into the core. It is free, with paid add-on readings.

The four pillars

AstroPal vs Co-Star, one question at a time.

Accuracy: what actually computes the chart

AstroPal

AstroPal computes every chart with the Swiss Ephemeris in the sidereal zodiac. Lahiri is the default ayanamsa, with Raman, KP and Krishnamurti selectable. Twelve divisional charts from D1 to D30, planetary strength and the full Vimshottari mahadasha and antardasha tree are calculated for every birth, not just the D1.

Co-Star

Co-Star gets more credit than it is usually given: the underlying planetary data is sound. The divergence is the reference frame. Co-Star works in the tropical zodiac, AstroPal in the sidereal, and the two are roughly 24 degrees apart, which is why most people land in a different sign under each. Neither is a calculation error, they are different traditions. But if you want Jyotisha, tropical will not give it to you, and Co-Star has no divisional charts, no planetary strength and no dasha tree because Western astrology does not use them.

Price: what it costs when you actually use it

AstroPal

One flat monthly price, and then nothing further. No per-minute meter, no per-report checkout, no charge for a follow-up question. The Kundali, Kundali Milan, Varshphal and baby name reports are free for everyone, PDF export included, and the entire Academy is open without an account.

Co-Star

Co-Star is free with paid add-ons, which is hard to beat on price alone. What the free tier gives you is a daily notification. AstroPal free gives you a fully computed Kundali, Kundali Milan compatibility, your Varshphal annual chart and the baby name report, all exportable to PDF, plus the entire Academy.

Reports: what you get in writing, and get to keep

AstroPal

Eleven full-length Vedic reports covering career, wealth, health, marriage, relationships, muhurat, numerology and Varshphal. Four are free forever. Every one is saved to your account, reopenable months later, and exports to PDF straight from the browser, with unlimited follow-up questions included.

Co-Star

Co-Star is built around the daily push. There is nothing to keep, nothing to export, nothing to reread in a year. AstroPal ships 11 long-form reports on career, wealth, health, marriage, relationships, muhurat, numerology and Varshphal, four of them free forever, each saved and PDF-exportable.

Academy: whether anyone will teach you the method

AstroPal

Eight structured courses with ordered modules, lessons and quizzes, free and open without an account. They run from reading a first birth chart through yogas, Saade Sati, the Vimshottari dasha tree, nakshatras and planetary strength, so you can check the reasoning behind any answer rather than trusting it.

Co-Star

Co-Star publishes short explainers. AstroPal runs 8 structured courses with ordered modules, lessons and quizzes, free and open without an account, covering the machinery Western apps simply do not have: yogas, the Vimshottari dasha tree, nakshatras, Saade Sati and planetary strength.

Choose AstroPal if

  • You want the chart computed with a named ephemeris you can check
  • You want one flat price that does not move with how much you ask
  • You want reports you keep, reopen and export to PDF
  • You want to learn the method rather than take an answer on trust

Choose Co-Star only if

  • You want Western astrology specifically, not Vedic
  • The social and friend-compatibility layer is the main appeal
  • You want a free daily notification habit and nothing heavier

The verdict

AstroPal answers the questions Co-Star has no method for: a sidereal chart with 12 divisional charts, computed planetary strength, dated Vimshottari periods, and 11 reports with 4 free that you actually keep. Co-Star is a very good Western app with sound planetary data, built around a daily push rather than a chart reading.

AstroPal vs Co-Star: common questions

Why is my sign different on AstroPal than on Co-Star?

Co-Star uses the tropical zodiac and AstroPal uses the sidereal, which tracks the visible constellations. The two have drifted about 24 degrees apart over the centuries, so many people are one sign earlier in Vedic astrology. Neither is a mistake; they are different traditions with different reference points.

Can Co-Star tell me when something will happen?

Not in the way Vedic astrology does. Western astrology has transits but no dasha system. AstroPal computes the full Vimshottari mahadasha and antardasha tree with dated timing charts, which is the classical method for timing events.

Co-Star is free. Is AstroPal?

There is a free tier, and it is substantial: a full computed Kundali, Kundali Milan compatibility, the Varshphal annual chart and the baby name report, all exportable to PDF, plus 8 free Academy courses that do not even require an account.
