Assalamu Alaikum!! This is a tasbih tool. When you click on the backdrop your dhikr increases by one. When you click on reset, Your count is reset and goes to Zero. If you clicked on the backdrop and forgot to say Dhikr, click on Back which minuses the extra. Best Dhikrs : ~ Astaghfirullah ~ La illaha illallah ~ Subhan Allah ~ Alhamdulillah ~ Allahu Akbar
