Your fast deserves more than a stopwatch. Fasten is a calm, private fasting companion for every tradition. Choose your faith or protocol and Fasten works out each fast's real start and end time from your location and the tradition's own calendar, counts it down, reminds you on time and keeps an honest record of your practice. 12 TRADITIONS, PLUS INTERMITTENT FASTING • Ramadan, Fajr to Maghrib with local prayer times • Sunnah fasts on Mondays and Thursdays • Orthodox Christian: Wednesdays and Fridays, Great Lent, the Apostles', Dormition and Nativity fasts • Coptic Orthodox and Ethiopian Orthodox fasting seasons • Catholic: Ash Wednesday, Fridays of Lent and Good Friday • Jewish: Yom Kippur, Tisha B'Av and the minor fasts • Hindu vrats and Navratri • Buddhist Uposatha, Jain Paryushana and Das Lakshana • LDS Fast Sunday and the Bahá'í Fast • Intermittent fasting: 16:8, 18:6, 20:4, OMAD or custom • Personal challenges with your own schedule Every plan shows its real rules, so you always know what the fast asks of you. DATES CALCULATED, NOT GUESSED Movable fasts come from built-in astronomical calendars: Hijri months from the new moon, the Hebrew calendar, Hindu lunar days, Western and Orthodox Easter, and Naw-Rúz from the equinox. Prayer and sun times use 13 recognised calculation methods with Standard or Hanafi Asr, matched to your country automatically. It all works offline. A TIMER YOU CAN READ AT A GLANCE A live countdown ring shows how far you are, what remains and the exact window of today's fast. Start, end or skip in a tap. REMINDERS THAT ARRIVE ON TIME Get a reminder before each fast, plus alerts at the start, halfway and the end, all scheduled on your device so they fire even with the app closed. WIDGETS AND LIVE ACTIVITY Keep the countdown on your home screen. On iPhone, a Live Activity follows a running fast on the Lock Screen and in the Dynamic Island. On Android, an ongoing notification does the same. SEE YOUR DISCIPLINE GROW • Calendar with completed, missed and upcoming fasts, plus the Hijri month • Log a past fast with your own times • Streaks, total hours, completion rate and personal bests • Weekly hours and monthly activity charts • A private weekly reflection journal SPEAKS YOUR LANGUAGE English, Arabic, Amharic and Hindi, with a full right-to-left layout for Arabic. PRIVATE BY DESIGN No account. No cloud. No ads. No tracking. Your location, if you share it, is used only to calculate sun and prayer times and never leaves your phone. Export a backup file whenever you like and restore it on a new device. Fasten is free, with no subscriptions or in-app purchases. Start every fast with purpose.
