Dates you can check, and adjust
Months can begin a day apart from one country to the next. Ibdar is honest about that.
Calculated on your phone
Ibdar follows the Umm al-Qura calendar (Saudi Arabia). It needs no internet and no location.
Confirm each new month
When a month begins, Ibdar asks whether it started as calculated, a day earlier or a day later where you live.
Reminders follow your answer
Up to three reminders, at the times you pick, with a short voice reminder in English or Arabic. Home-screen widgets show the next fast.
Private by design
Everything stays on your phone. Ibdar makes no internet request of its own.

Questions
Does Ibdar need the internet?
No. Every date and reminder is worked out on your phone.

Answer the monthly check with "a day earlier" or "a day later". Ibdar moves that month's fasts and reminders.
Which calendar does Ibdar use?
Umm al-Qura (Saudi Arabia) for now, with your monthly answers on top.
