Rayyan: Islamic Fasting

Track your Sunnah fasts and Ramadan — day-before reminders, a Hijri calendar of recommended days, streaks, and make-up (qada) tracking. 100% offline and private.

Rayyan is the focused fasting companion made just for Muslims — track your Sunnah fasts, Ramadan, and make-up (qada) days, and never miss a recommended day again.

Most fasting apps are built for intermittent dieting. Rayyan is different: it knows the Hijri calendar and every recommended fasting day — Mondays and Thursdays, the White Days (Ayyam al-Bidh), the Day of Arafah, Ashura, the six days of Shawwal, and Ramadan — and gently reminds you the day before, so you can plan ahead.

THE DAY BEFORE, NOT AFTER Get a warm reminder the evening before each recommended day: "Tomorrow is Monday — planning to fast?" No more missing the White Days because you lost track of the Hijri month.

ONE TAP, NO CLOCKS The Today screen shows exactly what today is and lets you log your fast with a single tap — start and finish, on your own terms. Rayyan deliberately does not show prayer times: it tracks days, not minutes, so you keep your own adhan app for timings.

A CALENDAR THAT TEACHES See your whole fasting month at a glance. Recommended days are highlighted; tap any day to learn what it is and why it matters, from authentic sources. Forbidden days (the two Eids) are clearly marked.

STREAKS & MAKE-UP TRACKING Build a lasting streak, see your fasts by type, and keep an exact count of your Ramadan make-up (qada) days — with a gentle monthly reminder until your count reaches zero.

THE IFTAR DU'A, ALWAYS THERE The du'a for breaking your fast — Arabic, transliteration, and translation — right on your home screen.

100% OFFLINE & PRIVATE Everything is calculated on your device. No account, no server, no internet needed — your data never leaves your phone. Works on a plane, on a mountain, anywhere.

EVERYTHING IS FREE Every feature is free for everyone: full fasting history with filters, weight tracking, CSV backup, and light & dark themes. Rayyan is supported by light, family-friendly ads — an optional one-time purchase removes them forever.

May Allah accept your fasts.
