Choosing software

Free vs paid astrology software — what you actually get

The right question is not whether software is free but what the paid tier changes. A free tier that computes the same charts as the paid one and limits convenience — devices, sync, exports, advanced modules — is honest. A free tier that computes a less accurate chart, and sells accuracy as an upgrade, is not.

Key takeaways

The line that matters: paying should unlock modules and convenience, never a better calculation.
Reasonable paid features: cloud sync, multi-device use, printable exports, advanced analysis modules, priority support.
Unreasonable: charging for the ephemeris quality, the ayanamsha choice, or the computation method.
Free tiers funded by advertising have a cost too — attention, and often the birth data.
In Jyotish Sarathi the siddhanta and ayanamsha settings are in the free tier: the calculation basis is not paywalled.

What a free tier can honestly cover

Chart generation is not expensive to run once the software is written, especially when the computation happens on the user's own device. So there is no technical reason a free tier cannot produce a complete, correct chart. A defensible free tier looks like this:

Full chart generation, including the divisional charts.
The dasha timeline in at least one system.
Panchanga and, for Nepal, the patro and date conversion.
The calculation settings — siddhanta and ayanamsha — because these determine whether the chart is right at all.
Use on one device, without an account.

What paying should change

Paid feature	Why it is a fair upgrade
Cloud sync and multi-device	Real server cost, and a genuine convenience rather than a capability the free user is denied
Printable cheena / PDF export	A professional deliverable; the people who need it are the people earning from it
Advanced analysis modules	Faladesh, matching, Ashtakavarga, Shadbala, KP — depth that a casual user does not open
Larger saved-profile storage	Storage has a cost
Ongoing feature updates	Funds continued development

What paying should never change

One line separates a fair pricing model from a dishonest one:

1The ephemeris. A free user should get the same planetary positions as a paying one. Selling "more accurate positions" means admitting the free chart is wrong.
2The ayanamsha choice. If a free user is locked to one ayanamsha, they cannot cast a chart that agrees with their own tradition. That is not a convenience limit; it is a correctness limit. See what is ayanamsha.
3The computation method. Same argument. Restricting the siddhanta to paying users makes the free chart unable to match a traditional panchanga.
4Chart completeness. A chart that silently omits planets or houses is not a limited version, it is a misleading one.

The hidden cost of "free"

Free software is funded somehow. The three common models are worth recognising, because their costs land in different places:

Advertising. You pay in attention, and often in data — an ad-supported astrology app has a commercial reason to know your birth details.
Data collection. Birth date, exact time and place is a precise identifier. If the calculation happens on a server, ask what is retained. See offline vs online.
A paid tier (freemium). The free users are subsidised by the paying ones. This is the model with the least conflict of interest, provided the line above is respected.

How to judge whether a paid tier is worth it for you

1Use the free tier for a week on real work. Not a demo chart — actual cases.
2Note what you actually reached for and could not use. If it is the export and the matching module, the upgrade is worth it. If it was nothing, it is not.
3Check that the paid tier does not change the calculation. If it does, that is a reason to be cautious about the whole product, not a reason to upgrade.
4Check the price in your own currency, and whether it is a subscription or a one-time purchase. Both are legitimate; know which you are buying.
5Ask for a trial for anything expensive. A vendor confident in the product will offer one.

In Jyotish Sarathi

The Free plan covers one device with chart generation, the divisional charts, dasha, panchanga, Nepali patro, transits and date conversion, plus both siddhantas and the full ayanamsha list. Paid plans — 3-month, yearly and lifetime, priced per platform and per region — add cloud sync, multi-device use, and the advanced modules: faladesh, kundali matching, Ashtakavarga, planet strength, KP astrology and the printable cheena. Full prices are on the pricing page.

Frequently asked questions

Is free astrology software accurate?

It can be exactly as accurate as paid software, because accuracy comes from the ephemeris and the settings rather than from the price. What matters is whether the free tier uses the same ephemeris and lets you choose the ayanamsha and computation method. If a program sells accuracy as an upgrade, treat that as a warning.

What should a paid astrology app add?

Convenience and depth: cloud sync, multi-device use, printable exports, and advanced analysis modules such as faladesh, matching, Ashtakavarga, Shadbala and KP. It should not add a better calculation.

What is included free in Jyotish Sarathi?

On one device: chart generation including divisional charts, dasha, panchanga, Nepali patro, transits, date conversion, and both the Surya and Drik Siddhanta settings with the full ayanamsha list. Paid plans add sync, multi-device use and the advanced modules.

Is a subscription better than a one-time purchase?

Neither is inherently better; they suit different situations. A subscription costs less up front and includes ongoing updates; a lifetime purchase costs more once and does not recur. Decide based on how long you expect to use the software and whether you want continued updates.
