Why there are two Asr times. The Hanafi school holds that Asr begins when an object's shadow is twice its own length; the Shafi'i, Maliki and Hanbali schools say once its own length. That is a real difference of an hour or more, and both are the practice of enormous numbers of Muslims. Pick whichever your masjid follows. The calculation method above does the same job for Fajr and Isha, where scholars differ over how far the sun sits below the horizon. If you are unsure, use whatever your local masjid prints.
These are calculated, not observed. Every method here is astronomy applied to a ruling, and your local masjid may differ by a few minutes for good reasons. Where they disagree, follow your masjid. In very high latitudes, where the sun may not set or rise properly for weeks, the calculations get genuinely difficult and scholars differ on what to do - ask locally rather than trusting any app, including this one.
Fasting today
Suhur endsالسحورStop eating and drinking at Fajr
IftarالإفطارBreak the fast at Maghrib
The fast runs from the first light of Fajr until sunset (Quran 2:187). Some timetables print an "Imsak" time a few minutes before Fajr as a precaution - that is caution, not obligation; eating is allowed until Fajr itself.
The night - qiyam, tahajjud and witr
Qiyam windowقيام الليلAny time between Isha and Fajr
The last third beginsالثلث الأخيرThe most beloved part of it
Qiyam al-layl is voluntary prayer in the night; prayed after some sleep it is called tahajjud. The Prophet ﷺ said our Lord descends in the last third of every night, asking: who calls on Me, that I may answer him? (Sahih al-Bukhari 1145). And: "The best prayer after the obligatory is the night prayer" (Sahih Muslim 1163). Close it with witr - "make the last of your prayer at night witr" (Sahih al-Bukhari 998). Nothing here is owed: even two quiet rakats count.
The qibla from where you are
NESW
You are facing the qibla
The needle shows the qibla as a bearing from true north. Face north, then turn by that angle.
On a phone, the dial can turn as you turn so the needle keeps pointing at Makkah. It needs your phone's compass, so it asks permission first.
The direction is worked out on your device from your coordinates. Nothing is sent anywhere to point you at Makkah.
If you are a little off, your prayer still counts. The Prophet ﷺ said "what is between the east and the west is qibla" for those praying away from the Kaaba itself (narrated by Abu Hurayrah in Jami' at-Tirmidhi). Do your best to face it and pray with a settled heart. A phone compass indoors can be pulled off by metal and electronics, so if the reading looks strange, step outside and check again.
