Did you know that we have another iMekka App called iMekka - Genie Edition? A new, magical and revolutionary App in the world of Muslims. It comes with augmented reality, hourglass, magiclamp, prayer times and much more...
iMekka 2 is the ultimate Mekka app on the iPhone AppStore. It is now available for free to the ones that bought the first version of it. (Updates should be free, even if there is a 2 attached to its popular name.)
Its a very simple and well-designed app to help you find your direction towards Mekka. Additionally it provides you with the prayer times and calendar dates of your current location, so that you will never miss a prayer.
Its predecessor iMekka was #86 in Navigation at the iPhone AppStore worldwide and still is the most popular of all Mekka apps.
Furthermore I want to say that the successor of iMekka is, again, an iPhone 3GS only application! You wont be able to see the beautiful compass rotate when you dont have the magnetometer inside your device.
Besides if you dont have the newest iPhone you can still see the prayer times of your current location.
