Core Features

Built with astronomical precision.

Designed to solve the real confusion of fasting dates across timezones while providing a calm, devotional space.

Location-Based Astronomy

Uses high-precision solar and lunar astronomical algorithms to calculate exact sunrise, sunset, Arunodaya (pre-dawn), and Tithi start/end times for your exact GPS coordinates or preset pilgrimage hubs (Vrindavan, Mayapur, Delhi, Bengaluru, London, New York).

Dual Tradition Support

Complete support for Gaudiya Vaishnava (ISKCON) rules — including Viddha Ekadashi avoidance, Mahadvadashi conditions, and Hari Vasara — alongside independent Smarta calculation rules.

Parana Fast-Breaking Engine

Calculates the exact morning time window for breaking your fast (Parana), taking into account Dwadashi tithi duration, sunrise timing, and Hari Vasara completion so you never break fast at an improper hour.

Interactive Calendar & Stories

Browse upcoming Ekadashis in interactive monthly and yearly calendar views. Each event includes its spiritual significance (Mahatmya), historical story, and practical fasting food guidelines.

Android Glance Widgets

Keep your devotion close at hand with native home screen widgets. View days remaining until the next Ekadashi and your exact morning Parana window directly on your home screen without opening the app.

100% Offline & Private

All astronomical ephemeris and calendar calculations execute entirely on-device via local Room persistence. No internet connection is needed, no account is required, and zero telemetry is sent anywhere.
