Here’s the number that tends to surprise people: a smart tasbih ring weighs about 6-7g. That’s lighter than most wedding bands. And a ring that light still carries a real battery, an OLED face, water resistance you can take through wudu, and a dhikr tally that runs into the tens of thousands.
So what are the full smart tasbih ring specifications, and what does each one mean once the ring is on your finger? This page gathers them and, more usefully, translates them: battery days into weeks between charges, an IP rating into safe-for-wudu, millimeters into a fit that stays put. Most single-product listings print the numbers and stop there.
Key Takeaways
Near 6-7g, with a 40mAh battery lasting about 15 days, up to 33 with a charging case (WESLAMIC product data, 2026).
IP67 is safe for wudu, handwashing and rain, not swimming or hot soaks.
Bluetooth 5.1 syncs dhikr to the app; the ring keeps your running count in its own memory.
Inner rings fit 16 to 24mm; only the FIT adds health sensors.
Battery Life & Charging: How Long It Lasts and How to Power It
Both the entry Salam and everyday Faith run a roughly 40mAh battery, per WESLAMIC product data. Worn bare, that runs about 15 days and idles far longer on standby. Entry models recharge via a magnetic contact cable in about 1.5 hours, while the premium Relation adds a 300mAh charging case that lifts combined runtime to around 33 days.
One figure gets muddled everywhere, so let’s be plain about it. That headline “33 days” is runtime with the charging case doing its job, not what a single ring holds on its own.
Worn bare, our product data rates the classic iTasbih-Faith at up to 15 days of use at about 500 counts a day, with standby stretching to roughly 30. The entry iTasbih-Salam is rated in the same range, roughly 10 to 20 days at that same pace.
How you top it back up depends on the tier. The iTasbih-Salam charges through a small magnetic contact cable, the kind you line up against the ring and leave for an hour or so. The premium iTasbih-Relation instead comes with a 300mAh charging case: the ring sips from it between wears, so you rarely count down to empty. Either way, topping up from empty runs about an hour and a half.
What does two-to-four weeks between charges actually buy you? Mostly, it keeps the ring out of your way. You’re not slipping it off mid-wird to hunt for a cable, and a forgotten charge doesn’t cost you the day’s remembrance. For a piece you mean to wear from Fajr onward, that steady reliability counts for more than any single figure on a sheet.
Water Resistance: What IP67 Means for Wudu and Daily Wear
Most smart tasbih rings carry IP67 water resistance, which in plain terms means you can keep one on through wudu, handwashing, rain and everyday sweat, but not swimming, bathing or long soaks in hot water. Brief and cool is fine; hot, deep or salty is not. Across our line, the entry iTasbih-Salam carries the one formally published IP67 figure, an IEC 60529 classification¹, while the rest are built for that same brief, cool contact rather than immersion.
Two practical points a bare rating won’t tell you. First, for valid wudu the water has to reach your skin, so a snug ring gets a small twist as you rinse; if you’d rather keep one on around the clock, the full-ring iTasbih-Peace1 is made for all-day, wudu-to-wudu wear. Second, IP67 does not clear the ring for showers or swimming, since hot water, steam, soap and salt strain seals in ways a depth rating never describes. For the full picture, including how IP67 differs from IP68 and what actually wears a seal down, see is a zikr ring waterproof. Wearing a ring through worship raises a fair question of its own, and are zikr rings halal takes that up properly.
Display, Counter & Count Capacity
A smart tasbih ring shows your tally on a small OLED screen and keeps the running total in its own memory. Our screens run from 0.42 inch on the entry Salam to 0.49 inch (72 x 35 px) on the classic Faith, and the tally holds on the ring itself, not only in the app.
Screen size is where the line splits by design, not just by price. The entry iTasbih-Salam reads on a 0.42-inch OLED; the everyday iTasbih-Faith gives you a slightly larger 0.49-inch panel at 72 by 35 pixels. The full-ring iTasbih-Peace1 goes the other way and carries no visible screen at all, keeping the count for the app. We don’t publish a display spec for the iTasbih-Relation, so we won’t guess at one.
Because the running total lives in the ring’s own memory rather than only in the app, a long tasbih session, or several days between glances, adds up without resetting on you. It also means your count holds even when your phone is nowhere nearby.
Sizes & Fit: The Interchangeable Ring System
Most smart tasbih rings solve fit with interchangeable inner rings rather than one fixed band. The classic Faith and premium Relation each ship with five swappable inner rings covering 16 to 24mm, while the entry Salam includes three, spanning 18 to 22mm. So one model fits most fingers straight out of the box.
This part is worth understanding, because it’s easy to picture wrong. The outer ring is the piece that reads your dhikr; the inner ring is a smaller sleeve that sets the diameter. Those swappable inner rings on our 2.0 line are ABS resin, not machined metal, which keeps them light and easy to change. Slot in the size that seats snugly, and you’re set.
Sizing systems differ across the line, so match to the model. The Faith and Relation use that 16-to-24mm set of five; the Salam keeps three. The health-focused iTasbih-FIT follows US ring sizes #8 to #13, roughly 18.2 to 22.3mm. The full-ring iTasbih-Peace1 runs its own numbering from #16 to #22, skipping #21. None of that is hard once you know the model, though it does mean a size in one system won’t read across to another.
Why fuss over a snug fit? Two reasons. A ring that seats properly won’t spin or slip while you count, and for valid wudu it still needs the small twist noted under water resistance above. If you are a brother still unsure a ring is even yours to wear, can men wear rings in Islam settles that question first.
Connectivity, App & Smart Features
A smart tasbih ring pairs to its app over Bluetooth 5.1, and that app is where your history, settings and prayer-time features live. WESLAMIC retail pages list Bluetooth 5.1 across the line, so you pair the ring once and your daily count moves to the phone on its own, no cable in sight.
Pair the ring one time, and the app keeps a running history of your dhikr, holds your preferences, and manages the prayer-time features you switch on. The everyday routine of counting, resetting and syncing sits in how to use zikr ring if you want the hands-on version.
Set your prayer times once in the app, and on any model with a motor the ring can stir gently at the hour, no sound needed. Which models carry that motor, and which trade it away, is the split we untangle next.
Vibration and Health Sensors: What Do the Higher Tiers Add?
Beyond the shared specs, two features separate the tiers: prayer-time vibration and health sensors. Gentle vibration reminders sit on the everyday Faith, the premium Relation and the full-ring Peace1, while the health-focused iTasbih-FIT adds heart-rate, blood-oxygen, sleep and step tracking. No model carries both a vibration motor and the full sensor suite.
First, a correction most spec sheets get wrong. Prayer-time vibration isn’t a premium-only feature. It’s on the everyday iTasbih-Faith just as it is on the pricier iTasbih-Relation and the full-ring iTasbih-Peace1. The entry iTasbih-Salam doesn’t list it. And the Peace1 goes one step further: it’s the only model that lets you customize the vibration pattern itself.
Now the trade nobody spells out. The iTasbih-FIT is the 3.5 health model, and to make room for its health sensors plus a Fajr check-in, it leaves out the vibration motor entirely. Read that carefully, because it has a real consequence: the FIT can track your morning prayer, but it can’t buzz your finger to remind you of one. So which model actually nudges you toward prayer? Any of the three with a motor, just not the FIT.
For someone who wants faith and fitness in one piece, the FIT still earns its place: it logs your health metrics alongside your dhikr, and quietly notes whether you caught Fajr. That’s a different promise from the rest of the line, which leans toward faith jewelry you keep on for its own sake, counting or not.
Specifications by Generation & Model (Comparison Table)
As of mid-2026, one line covers the essentials before the full grid: a smart tasbih ring weighs about 6-7g, runs a roughly 40mAh battery for around 15 days (up to 33 with a charging case), shows a 0.42 to 0.49-inch OLED screen, holds IP67 water resistance safe for wudu, syncs over Bluetooth 5.1, and fits interchangeable 16 to 24mm sizes.
Higher tiers layer on gentle vibration prayer reminders or health sensors, and the numbers shift a little from model to model, which is exactly what a single-product spec sheet can’t show you. Below is the current line, five series across three generations, lined up so you can read across instead of one at a time. One naming note before you do: a generation like 2.0 or 3.0 is a family label, not a model name, so there’s no product literally called “iTasbih 3.0.”
Model | Generation | Battery and charging | Sizes | Prayer-time vibration | Screen |
|---|---|---|---|---|---|
iTasbih-Salam | Smart Tasbih 2.0, entry | 40mAh, about 10-20 days; magnetic contact cable | 3 swappable inner rings (18-22mm) | Not listed | 0.42-inch OLED |
iTasbih-Faith | Smart Tasbih 2.0, classic everyday | 40mAh, up to 15 days; recharges in about 1.5 hours | 5 swappable inner rings (16-24mm) | Yes | 0.49-inch OLED (72 x 35 px) |
iTasbih-Relation | Smart Tasbih 2.0, premium | 300mAh charging case, about 33 days combined | 5 swappable inner rings (16-24mm) | Yes | Not published |
iTasbih-Peace1 | Smart Tasbih 3.0, full-ring | All-day, everyday wear | Own numbering (#16-#22) | Yes, customizable | No visible screen |
iTasbih-FIT | Smart Tasbih 3.5, faith + health | Health sensors on-ring | US ring sizes #8-#13 | None (no motor) | Screen and touch (size not published) |
A word on that last column, since it’s where the specs get misread: see the vibration section above for which models buzz and how the FIT differs. Our lineup runs five series across three generations; to compare how each sits on the hand, See all smart tasbih ring.
Smart Tasbih Ring Specifications FAQ
Which smart tasbih ring in the line lasts longest between charges?
The premium iTasbih-Relation, thanks to its 300mAh charging case: WESLAMIC product data puts combined runtime near 33 days. Worn bare without a case the ratings run closer together, with the entry Salam rated up to 20 days and the classic Faith up to 15, both at about 500 counts a day. See the battery section above for how bare-versus-case runtime works.
Can a smart tasbih ring remind me of prayer times without my phone?
On models with a vibration motor, yes. Once you set prayer-time reminders in the app, the ring can buzz gently on its own, even with your phone in another room. That on-ring nudge is available on the Faith, Relation and Peace1. It runs on a quiet vibration rather than a sound, so it stays private.
Can I wear one in the shower or while swimming?
Better not. IP67 water resistance is built for brief, cool, fresh water: wudu, handwashing, rain and sweat. A hot shower adds heat, steam and soap that wear seals over time, and swimming adds pressure and salt beyond the rating. So once water turns hot, deep or salty, that is the cue to slip the ring off.
I mainly want prayer reminders. Is the health-focused FIT the right pick?
Probably not. The iTasbih-FIT trades the vibration motor for its health-sensor suite, so it can track your Fajr but can’t buzz a reminder. If a gentle prayer-time nudge is your priority, the everyday Faith or the full-ring Peace1 fits better. Choose the FIT for fitness, not for alerts.
