Zarrah is a daily planner for Muslims, built around your five daily prayers. Plan your day, build habits around salah, track your fasts, and block distracting apps when you need to focus. HABIT STACKING AROUND SALAH Read two pages of Quran after Fajr. Take a walk after Asr. Journal after Isha. Attach a new habit to a prayer you already observe, then set its schedule and check it off in your daily plan. PLAN YOUR DAY BETWEEN PRAYERS See tasks, habits and prayer times together. Schedule something at a fixed time or before or after salah, so you can plan work, study and family time around prayer. FASTING THROUGHOUT THE YEAR Plan Ramadan, Monday and Thursday fasts, the White Days, and make-up fasts. See Fajr and Maghrib times, set suhoor and iftar reminders, and look back at the fasts you completed. FOCUS AND APP BLOCKING Start a focus timer for study, work or worship. Choose distracting apps to block during your session on supported devices. Review your focus activity over time. SISTER MODE Record periods on your calendar and keep track of Ramadan fasts you need to make up. Protect habit streaks on days you mark as exempt from worship. You choose which prayers and fasts are affected. WATCH YOUR HABIT GARDEN GROW Check off your habits and see your effort take shape in a garden. Look back through your history to see what you completed and where to pick up again. PRAYER TIMES AND ALARMS See the next prayer and set a reminder before, at or after each prayer time. Adjust calculation settings to match the method you follow. HIJRI AND GREGORIAN CALENDARS Switch between both calendars to plan daily life and Islamic dates. View moon phases and browse past days to review your activity. Privacy Policy: https://zarrah.app/privacy Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
