Everything around the five daily prayers, explained clearly: how to perform salah and wudu, how to find the Qibla anywhere, how to set adhan notifications that actually work, and how prayer times are calculated — including why two apps can show different times for the same city. Articles covering religious rulings are reviewed for accuracy before publication.
The adhan arrives on time, at a volume you can hear, and you carry on with what you were doing. That is not a delivery fault. It is a documented property of repeated signals, and it has two research-backed levers.
The figure-of-eight motion fixes one kind of compass error and does nothing for the other. Knowing which fault you have is what decides whether waving the phone helps or wastes your time.
When the adhan does not sound, the app is rarely the problem. The phone is silencing or delaying it, through Focus on iPhone and battery optimisation on Android. Here are the exact settings that stop it.
The qibla is an angle measured from true north, and from almost every US city it runs northeast. Four methods can give it to you, they fail for unrelated reasons, and the sun's widely quoted dates are not the ones that work here.
Most apps list "works offline" as a feature and leave it there. The more useful question is why: prayer times are astronomy computed on the device, the qibla is a bearing between two coordinates, and the parts that stop are the ones that were always a search.
A prayer time is not a clock time. It is a position of the sun, converted for your exact coordinates on one exact date. The astronomy is settled; the disagreements between honest timetables come from the two numbers people had to choose.
Seventeen minutes between two phones in the same city, and neither app is at fault. Prayer timetables are built from conventions; which prayers disagree tells you which setting differs, and your mosque's schedule tells you which one to match.
After a flight, a prayer app usually shows the wrong times because its location is stale, not because its clock is. Which prayers are wrong tells you which setting to fix.
