# Supastro compared to other apps

Head-to-head comparisons between Supastro and other Vedic and AI astrology apps, covering the calculation stack, what each computes, how each handles uncertainty, and what is free versus paid. Comparisons are written against verifiable feature differences rather than marketing claims.

## How is Supastro different from other AI astrology apps?

Most AI astrology products are a language model prompted with a chart summary — the astrology is generated prose. Supastro computes the astrology first and constrains the AI to those computed values. Concretely that means divisional charts to D60 and higher vargas to D150, Ashtakavarga to the full 337-point system, Shadbala across six sources, and Vimshottari nested five levels deep, all derived from NASA JPL ephemeris data. It also declines to answer where the input data cannot support a conclusion, which a prose generator has no mechanism to do.

## What should you compare when choosing a Vedic astrology app?

Four things are worth checking. What astronomical source the positions come from, since everything is downstream of that. How deep the divisional charts go, because D9 alone is common and D60 is not. Whether dasha timing is nested beyond mahadasha and antardasha. And whether the app tells you when it cannot answer — an app that always has a confident answer is generating prose, not reading a chart.
