the apps is working well in my Motorola milestone android 2.1 Namaz Vakitleri is Turkish which means prayer time. You can choose where you are or where you want to be, and it will calculate the 5 Muslims prayer time plus Imsak and sunrise time. It can be updated based on your gps location or you can pick and choose from the thousands of cities listed in the apps. I am in Malaysia (Kuala Lumpur) and I have detected 2-4 minutes differences between the apps prayer time and local prayer time. The method of calculation used was not mentioned, but I believed they used the Imam Malik method, whereas we in Malaysia uses the Imam Syafie method. Nothing wrong from the differences though. This might be the first effort from the Muslims world to join the android bandwagon, and I applaud the simplicity and ease of use.
