Rayyan: Islamic Fasting

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.
