A free app for Android, by Srujan Jha.

This app contains the complete text of Siddhanta Kaumudi, a famous Sanskrit commentary written by Bhaṭṭoji Dīkṣita.

The app is a tool for studying the text and is intended to be used by students, teachers, and anyone interested in learning more about the Indian commentaries on the Aṣṭādhyāyī.

Siddhanta Kaumudi is divided into two parts. The first part contains the rules of interpretation, sandhis, declensions, formation of feminines, case endings, compounds, secondary derivations, and the second part with conjugation, primary suffixes, Vedic grammar, and accents.

The app contains all the sutras and is arranged in the same order as in the original text.
