Why we make dhikr
Dhikr is the remembrance of Allah - keeping the heart and tongue busy with His praise. The Quran commands it directly: 'O you who have believed, remember Allah with much remembrance' (Surah al-Ahzab 33:41), and promises its fruit: 'in the remembrance of Allah do hearts find rest' (Surah ar-Ra'd 13:28). A tasbeeh simply helps you keep count as you remember Him, so your tongue can stay with the words while your heart stays present.
The tasbeeh after every prayer
A beloved sunnah is to glorify Allah after each obligatory prayer. The Prophet (peace be upon him) taught that whoever says SubhanAllah thirty-three times, Alhamdulillah thirty-three times, and Allahu Akbar thirty-three times after every prayer - that is ninety-nine - and completes the hundred with 'La ilaha illa Allah, alone with no partner', his sins are forgiven though they be like the foam of the sea (Sahih Muslim 597a). This counter uses a well-known thirty-three / thirty-three / thirty-four pattern to reach one hundred (Sahih Muslim 596a).
Beads, fingers, or a screen
Counting dhikr on the fingers is the way of the Prophet (peace be upon him), who told us to count on them, 'for they will be questioned and made to speak' (Sunan Abi Dawud 1501). Many scholars also allow aids such as prayer beads or a digital counter, while others prefer the fingers - so treat this tool as a convenience, not a ruling. What matters most is the presence of the heart. Your count stays on your device and is never sent anywhere.
Salatul Tasbeeh
Beyond the daily adhkar there is a special voluntary prayer built entirely around tasbeeh. In it, the worshipper recites 'Subhan Allah, walhamdu lillah, wa la ilaha illallah, wallahu akbar' seventy-five times in each of four rakahs - three hundred times in all - woven through the standing, bowing, and prostration. It is reported that the Prophet (peace be upon him) taught it to his uncle al-Abbas with the words that it would forgive sins 'the first of them and the last' (Abu Dawud 1297). Scholars have differed over the narration's strength, and many through history have prayed it occasionally - some on Fridays, some in Ramadan, some once in a lifetime - so learn it, and pray it as an extra act of devotion if you wish, without treating it as obligatory.
Using this counter
Tap anywhere on the big counter - or press the space bar - to count; the ring fills toward your target and glows when you reach it. The after-salah preset advances by itself through 33, 33, 34, with a distinct vibration at each transition on phones that support it, so you never lose your place between the three phrases. You can set any custom target for other adhkar, keep a daily streak with a seven-day view of your consistency, and turn on a soft tick sound if you like feedback you can hear. Everything is saved only on your device: no account, no cloud, no tracking - your dhikr is between you and Allah.
