3. Comprehensive Astrological Tools

Explore detailed planetary positions, vargas, chakras, and upcoming transits calculations to deepen your astrological insights.
Seekers and students of Jyotish have been given a dedicated Learner's corner with learning aids and tools for analysis/predictions. The focus here is mostly on practical application of theoretical concepts.
Built-in interpretation guides and reference tables assist beginners while offering advanced tools like customised lucky weekday/direction selection and planets in chakras, directional (RG Rao nadi) chart, numerological turning points in life for seasoned practitioners and seekers.
Focus of LagnaOne is not just to be another available option amongst Jyotish softwares - there are many good ones available for free as well as paid. LagnaOne is about adding practical value at every step of the way. It goes beyond displaying the calculation, tables and charts. The vision of LagnaOne's author is to free Jyotish from the usual bureaucracy by means of having conclusive practical actions points as outcome of Jyotish application. Using Jyotish to enrich lives and better understand our karmic progression is the vision that drives it. It's far from being perfect but it's designed to grow with the community.

4. Flexible for All Users

Students: Learn Vedic astrology with students corner that help in honing application skills at earlier stages of learning Jyotish, making complex artifacts and abstract concepts more comprehensible while reading charts.

Why LagnaOne Stands Out

LagnaOne astrology software isn’t just an astrology tool—it’s a bridge between traditional wisdom and modern technology to maximise the value of that wisdom to enrich our lives today. Whether you’re casting your first chart or conducting advanced research, its blend of precision, accessibility, and modern design empowers you to explore the cosmos with confidence. By being forever free and fully offline, it removes barriers, making the profound wisdom of Jyotish available to all.

Future version for which development is going-on in full swing will integrate Ayurveda fundamentals and more dasha systems - that's a promise. LagnaOne is designed to widen the tunnel-narrow view of modern (and popular) Jyotish practice to something more profound and "cosmic", that Jyotish was originally devised to be. However, this will be done whilst fully utilising the insights provided by technology.

About the Author

Partho Banerjee is a Jyotishi or Vedic astrologer as popularly called these days, as well as passionate applications software expert dedicated to making actionable Jyotish tools accessible to all.

This Astrology software is created, owned, managed and maintained by Partho Banerjee, that’s me. LagnaOne is designed to grow for and with the Jyotish community.

My journey in IT: I have been a full time IT and software professional for 14 years and have done Master's in Computer Applications. I am certified corporate IT trainer by Indian Institute of Technology (IIT) Kanpur, India and IBM Corporation. I have worked with leading IT companies in banking and financial services domain at global cities including London, Singapore, Mumbai, Copenhagen, Hong Kong etc.

Astrology: My journey in Jyotish or Vedic astrology as popularly called, numerology and spiritual sciences began in the year 1999 and I started informal horoscope analysis in the year 2001. All through that decade, I was pursuing my full time job in the IT along-side my quest in astrology in parallel.

In my eventful journey of more than a decade and half as practicing astrologer, I have done consultations for people from different walks of life across various cultures and countries (thanks to the internet).

In my view, Astrology is all about understanding root cause analysis and karmic healing required to handle/help in major obstacles in life - child birth issues, delayed marriage or serious relationship/marriage issues, career counseling and opportunities/challenge analysis, legal disputes, debts and loans, or other long/short term planning and decisions in life.

If you wish to know more about my astrology journey or want to connect with the astrologer in me, here is my astrology page☞ AstrologyOfBharat.org

I welcome you to make full use of LagnaOne software that I have passionately crafted for every Jyotish seeker like you. In coming months I will release newer versions with more feature and changes based on feedback from the community. This is a "forever free" and offline software.

Warm regards
Partho Banerjee
