Free to apply in your browser. A person reads your application and decides within 2 days.

Short answer

Astrologers cast charts with a handful of programs. Jagannatha Hora is free for Windows ¹, and Parashara's Light 9.0 costs $299 for Windows or Mac ³. Shri Jyoti Star 10 is a free Microsoft Store download with paid options ⁵, Future Point's LeoStar-I is a free PC download ⁸, and AstroSage Kundli runs on Android ⁹. All of them calculate positions, divisional charts and dashas; none of them reads the chart for you. To apply to Kismo you need no software at all: the client card in the test reading already shows the birth details and the chart.

Free on Windows: Jagannatha Hora 8.0, by P. V. R. Narasimha Rao ¹
One-time price: Parashara's Light 9.0: $299, Windows or Mac ³
Subscription model: Shri Jyoti Star 10: free download, paid in-app options ⁵
Indian languages: LeoStar: more than 12 languages, including Hindi and Tamil ⁷
On a phone: AstroSage Kundli: free, with ads and in-app purchases ⁹
Check first: Ayanamsa, chart style and time zone ^2,9

The job

What does astrology software do for an astrologer?

Astrology software turns a date, time and place of birth into planetary positions, divisional charts and dasha periods in seconds. Jagannatha Hora, for example, draws 23 divisional charts and checks a chart for 184 kinds of yoga ².

What software cannot do is decide what matters for the person asking. It lists every yoga it finds; you choose which two or three answer the question.

Price list

Which astrology software do astrologers use, and what does each cost?

Five programs cover most needs, from free to a few hundred dollars. Each price below is the one stated on the maker's own page or store listing on 5 November 2026.

Strengths

What does each astrology program do best, by its maker's account?

Program	What the maker highlights	Worth knowing
Jagannatha Hora	23 divisional charts, custom ayanamsa, Prasna Marga's sphutas ²	Will not run on Mac, iPhone or Android, though some use Windows simulators ¹
Parashara's Light	Over 120 pages of tutorial, a world atlas that fills in time zone and daylight saving ¹⁰	Software is refunded only within 2 weeks, if never activated, and for technical reasons ³
Shri Jyoti Star	Prashna for KP and Prasna Marga, muhurta, rectification ⁴	V10 removed the three-level limit on dasha display ⁵

Parashara's Light sells a version 7.0 demo for $15 ³, and Shri Jyoti Star offers a free trial of V10 ⁴. Use them before you pay full price.

Settings

Which settings should you check before you trust a chart from software?

Three settings change the chart itself: the ayanamsa, the chart style and the place data. Check them once, then keep them the same for every chart.

Ayanamsa: Jagannatha Hora offers Lahiri, Raman, Krishnamoorthy and others, plus your own custom value ²; AstroSage offers Lahiri, Raman, KP and Sayan ⁹.
Chart style: AstroSage draws North and South Indian charts ⁹; pick the one your clients know.
Time zone and daylight saving: Parashara's Light's atlas fills these in ¹⁰, and AstroSage corrects daylight saving automatically ⁹.
Date range: Jagannatha Hora's short install has accurate ephemeris only for 1800 to 2400 AD; the 102 MB full install covers far more ¹.
Atlas size: the full Jagannatha Hora install carries 2.5 million cities ¹, which helps with small towns.

Cast your own chart in two programs and compare the lagna degree. If they differ, one of these settings differs.

Free or paid

Is free astrology software good enough for paid client work?

Free astrology software is good enough for calculation, which is what the chart needs. Jagannatha Hora's maker describes it as built for serious Vedic astrologers and researchers ¹.

Paid programs add tutorials, printed reports and support. Parashara's Light, for example, lets you track who you printed reports for and when ¹⁰. Pay for those extras only if you will use them.

If you are still learning, start free. Our page on free astrology courses pairs the free software with free texts.

Special work

Which astrology software suits KP and prashna work?

For KP and prashna, choose software that names those methods in its own feature list. LeoStar lists a KP module with the 249-number system and a horary module ⁷, and Shri Jyoti Star lists prashna for KP and Prasna Marga ⁴.

On a phone, AstroSage offers KP tables and GPS support for prashna kundli ⁹. Jagannatha Hora computes the deha, prana and trisphuta values of Prasna Marga ². The methods themselves are on prashna kundli and KP astrology.

On Kismo

Do you need astrology software to read on Kismo?

You do not need any software to apply to Kismo: you apply in a browser, and the test reading's client card already shows the client's birth details and chart.

Situation	What applies
Applying	In a browser at kismo.app/astrologers; free
The test reading	Chart on the client card; answers typed by you, pasted answers sent back
Reading online after approval	Stay on screen: 15 minutes in the background sets you offline
Devices	Browser, the Android app, or Safari on iPhone added to the Home Screen

If you cast extra charts while online, do it on a second device, so Kismo stays open and you do not miss a 30-second request.
