What Sawm does, screen by screen
Sawm is built around one question each day: are you fasting today? Everything else — the calendar, the Qada balance, the suggestions and the statistics — follows from your answer.
Imsak and iftar times
Your fast, at a glance
The home screen counts down to imsak before dawn and to iftar during the day, for the city you choose. Times are calculated by the method your country follows — Umm al-Qura in Saudi Arabia, Diyanet in Turkey, the Muslim World League where no national method is listed — and told in that city's own time zone.
- One tap records today as fasted or not fasted.
- Your streak and your best streak, on the same card.
- The Hijri date and the Gregorian date, side by side.

Hijri calendar
Every fast on the Hijri calendar
Every month in Hijri or Gregorian, with each fast you kept, missed or planned in its own colour, and the Sunnah days marked before they arrive: Mondays and Thursdays, the White Days, Arafah, Ashura and Shawwal. Ramadan, the two Eids and the days of Tashreeq are never offered as Sunnah fasts.
- The Hijri date follows the date announced for your country, or an offset of up to two days that you set.
- Plan a fast for a day ahead and get a reminder the evening before.

Qada tracker
Make up missed fasts
Missed fasts from Ramadan are kept as a balance for each year, and every make-up fast you record brings it down. The balance shows how many days are left before the next Ramadan and how many fasts a week will finish it in time.
- Fidya, for days that cannot be made up, has its own tab.
- A Qada reminder you can set for the days that suit you.

Smart suggestions
Smart suggestions
Sawm looks at the coming days and suggests the ones that suit you best: Sunnah days first, scored by the weekdays you prefer, how long the fast lasts in your city and, if you turn weather on, the forecast — a shorter or cooler day is easier to fast.
- Each suggestion shows why it was chosen.
- The free app looks 7 days ahead; Sawm Pro looks 14.

Statistics
Watch your record grow
Totals for every kind of fast, your longest streak, a month-by-month chart of the year and your Ramadan performance, all worked out on your phone from your own record.
- The free app shows your latest Ramadan; Sawm Pro shows every year.

Insights
Small steps add up
A short insight each day, the patterns in how you fast, and milestones along the way — your first fast, seven days in a row, fifty Sunnah fasts and more.

And the rest of it
Reminders
The evening before each Sunnah fast you keep, before a fast you planned, ahead of Ramadan, and at the times you choose for suhoor, your daily intention and your Qada.
