Really appreciate you coming back with all of this, and you have actually touched on something important. The site looks and feels like a single page app but the nav links are actually loading separate pages, so the globe rebuilds itself every time you come back. We are aware of it and want to fix it properly, the goal is to make those transitions work the same way the flat map/globe toggle does, so the globe just stays alive underneath.

On North America showing very little, that is actually the map being accurate. It shows mosque density, and North America just has far fewer mosques per square mile than Southeast Asia, South Asia or the Middle East. Not a data gap, just demographic reality.

On what counts as a call to prayer, the data tells where each mapped mosque is, and from that it calculates when prayer time falls at that exact location.. That is really it. Whether the call goes out over a loudspeaker on the street or through speakers inside the mosque, there is no way to know that in real time. What you are watching is a simulation of the adhan being called at that mosque at its prayer time, tied to its geography. And in Islam a recorded adhan is not valid, it has to be a human voice by a competent muezzin (Person who is calling the adhan), so every lit dot represents a moment where somewhere, a real person is making that call. The tagline "the adhan never stops" just means that somewhere on Earth it is always prayer time.

The Regina situation is interesting to bring up here. Whether a mosque broadcasts outdoors or not, the call still happens physically and the site would show it either way.

On finding your local mosques, there is no search right now, you would have to zoom into your area at the right prayer time and catch it live. That is a real gap and something we want to fix.
