Description:
Mecca Finder is a simple tool for finding the direction of Mecca (Makkah al-Mukarrama), the holiest meeting site of the Islamic religion. The application is designed to work regardless of where you are in the world. The display points an arrow in the direction of The Kaaba (al-Ka’bah). The arrow indicates the Qibla (Kiblah), or direction that should be faced when a Muslim prays during Salah.

Operation:
In keeping with the KLR Applications philosophy of deploying the simplest possible user interface, the Mecca Finder application requires only that you start up the program. The software does the rest. No configuration required.

If you are using the iPhone 3GS, the arrow will point in the direction of Mecca, regardless of which way you are facing. It will continue to point in the proper direction as you turn. Other devices (the iPod Touch, the original iPhone, and the iPhone 3G) do not have a built-in compass and must be manually pointed toward true north in order for the arrow to point in the right direction.

Notes:
The iPod Touch is only able to determine direction by wi-fi triangulation. Therefore, the application will generally only work in certain urban areas.
The original iPhone goes not have GPS capability. It therefore relies on cell tower triangulation to determine your location. If you do not have a good signal, it may not be able to figure out where you are. The same is true when using the iPhone 3G and iPhone 3GS indoors, where GPS signals do not reach.
When using this, or any compass-based application with the iPhone 3GS, it is important to stay away from artificial magnetic fields. These include music speakers, motors, refrigerator magnets, computers, electric and hybrid cars, etc.
