Did you forget which rakaat you are on while praying? You are not alone in this!
Now you never need to keep count of your rakaat - Top Namazi will count your rukus automatically and you can focus entirely on your prayer!
Simple place the phone in portrait with camera on and cover your head to feet in view. The app will automatically detect that you have started prayer and count each ruku. The total counts are shown in large text on the screen which you can see with a simple glance - the app also speaks the total as it is updated.
