Digital tasbih counter

Tap anywhere on the counting area once for each repetition, saying the phrase silently or aloud as you tap. Set a target such as 33 or 100 and the counter tells you when the number is reached; undo corrects a stray tap. The count is still there when you close the tab and come back, because it is stored in your own browser.

Neither is required, and both are permitted as tools for keeping track. A digital tasbih counter is easier for large numbers, does not need to be carried, and can run a fixed sequence such as Tasbih Fatimah for you. Beads give a tactile rhythm many people prefer. A fuller comparison is at digital versus physical tasbih.

The majority of contemporary scholars permit it, because the counting tool is a means of keeping track and not part of the worship itself. Counting on the fingers of the right hand is the practice reported from the Prophet ﷺ (Sunan Abi Dawud 1501) and is considered the most virtuous method, so many people reach for a counter only when the number is large.

The best known is Tasbih Fatimah after each obligatory prayer: SubhanAllah 33 times, Alhamdulillah 33 times, Allahu Akbar 34 times, recorded in Sahih Muslim 596. Others set 100 for salawat or istighfar, 99 for the names of Allah, or a personal daily wird of 300 or 1000.
