It’s a common problem – praying and forgetting which rakat you are on – but the Smart Rakat Counter seeks to help with it!
The smart little portable device, created by SmartDeen is an aid for concentration in your prayers. It helps to count the number of Rakats while in Salat. Simple to use, you just place the device at the top-left corner of your prayer mat and it will automatically displace the number of times you have done your sajda.
While you focus on your prayer, the device displays the count!
