A Hindu vrat & tithi tracker
A calm companion for the rhythm of your day.
Know when to fast, when to break, and why the date falls where it does — for your city, your tradition and your family.
Dates for your own sky
Sunrise, moonrise and tithi times computed for your city. Family in another time zone? See both skies side by side.
Every tradition, clearly
Smarta, Vaishnava and ISKCON Ekadashi. Purnimanta, Amanta and solar calendars. Niyam shows where they agree and explains where they don't.
The "why" behind every date
Tap any observance to see the rule, the numbers and a plain-words explanation: "Sankashti is kept on the day Chaturthi is running at moonrise."
Gentle reminders
Preparation the evening before, sankalp at sunrise, moonrise, parana window open and closing. You choose which ones, and when.
Live Activity & widgets
On fasting days, a Live Activity shows the next anchor and a countdown on your Lock Screen. Home Screen and Lock Screen widgets keep the tithi and the next vrat visible.
