Sleep tracking worn on the wrist works reasonably well. Sleep tracking on the finger is generally considered more accurate because the optical sensors sit closer to blood vessels and the signal is cleaner.

The R6 monitors heart rate, blood oxygen (SpO2), blood pressure, heart rate variability (HRV), sleep stages, sleep body temperature, and daily step count. It connects via Bluetooth to a companion app for trend data and analysis.

Battery capacity is 18mAh. The ring charges in a case, similar to a wireless earbud case. The ring itself is waterproof.

Available in three colors (black, silver, gold) and five sizes (No. 8 through No. 12). Sizing matters for both comfort and sensor accuracy.

1. Select the correct ring size. The ring should sit snugly but not tightly, with the sensor panel on the inside of the finger.
2. Charge fully before first use using the provided charging case.
3. Download the companion app and complete Bluetooth pairing.
4. Wear on whichever finger you find most comfortable. Many people use the index or middle finger of their non-dominant hand.
5. For sleep tracking, wear the ring to bed. Sleep stage data will appear in the app the next morning.
6. Charge in the case when the app shows a low battery indicator.

Sizes No. 8 through No. 12. Measure ring size carefully before ordering. Sizing affects comfort and sensor accuracy.

Changed how I think about recovery

The recovery score feature is what I use most. It tells me if I should push hard or rest. My training has been more efficient since listening to this data.

M
Melissa
Heart rate monitoring is on point

I checked my heart rate against a chest strap during a run. The ring was within 2-3 bpm the whole way. That's accurate enough for my needs.

S
Simone
Accurate step counting

Compared to my phone pedometer and another fitness tracker — the step count on this ring is consistently accurate. Impressed by the hardware.

B
Beverly
Didn't expect to love it this much

Bought on a whim during a sale. It's now an essential item — I feel off if I forget to wear it. Tracks everything I care about and does it reliably.

A
Alice
Works perfectly in the gym

Tracks sets and reps? No. Tracks heart rate zones and recovery? Yes. That's what I need from a gym wearable and this delivers it without bulk.

G
Georgia
Great concept, good execution

Smart ring technology is still maturing but this one does it well. Good sensors, reasonable app, comfortable fit. A few software bugs but nothing major.

D
Denise
Replaced my smartwatch

I hated wearing a bulky watch to bed. This ring tracks all the same things and I don't even notice it on my finger. Sleep data is accurate.

E
Elena
Lightweight and elegant

It's so light I forget I'm wearing it. The design is clean and minimal. No one guesses it's a smart device unless I tell them.

K
Keiko
Good sleep tracking

The sleep stage breakdown in the app is detailed and feels accurate — I've cross-referenced it with a medical sleep study and it was fairly close.

S
Sabrina
Solid product, minor app issue

The ring itself is excellent. The app crashed a few times in the first week but has been stable since an update. Hardware quality is great.

P
Patricia
Perfect for health-conscious professionals

I'm a physician and recommend wearables to patients. This ring is one I'd actually wear myself — non-intrusive, accurate, and doesn't scream medical device.

O
Olga
The camera function surprised me

The camera remote trigger feature is actually really useful. Takes photos with a small tap on the ring. Sounds gimmicky but I use it regularly.

I
Iris
Good ring, slight learning curve

Takes a few days to understand all the features and what the data means. Once past that it's very useful. Would benefit from better onboarding in the app.

L
Leonard
Battery life is impressive

Charged it Monday, it's now Saturday and still at 40%. For a ring with multiple sensors that's genuinely impressive battery management.

B
Bernard
Size guide is accurate

The sizing tool on the product page is accurate. I measured with a ring sizer and the recommended size fits perfectly. Good to know before ordering.

G
Gregory
Best wearable purchase

I've owned a smartwatch, fitness band, and now this ring. The ring wins for everyday comfort and I don't have to charge it every night.

S
Stuart
Wore it swimming, works fine

Waterproof as advertised. I swim 3x a week and it's survived every session. No issues with the touch functionality after water exposure either.

F
Frank
Solid health tracker

Step count, heart rate, sleep stages — all working well. The app is basic but functional. Battery lasts about 5-6 days for me.

R
Rodney
Great gift for health enthusiasts

Got this for my brother who is into biohacking. He's obsessed with it. Said it's one of the most interesting gadgets he's ever received.

W
Wayne
Sleep data changed my habits

Seeing how little deep sleep I was getting motivated me to change habits. Alcohol reduction and earlier bedtimes showed up immediately in my sleep scores.

S
Samuel
Husband and wife both got one

We both track sleep now and compare data in the app. Oddly motivating to have friendly competition on sleep scores. Both of us sleep better now.

B
Brad
Finally a discreet wearable

No one knows I'm tracking health data. It looks like a regular ring. For people who find smartwatches visually overwhelming, this is perfect.

G
Gary
Good but app needs work

The ring hardware is excellent — comfortable, accurate, good battery. The companion app is functional but could use a design overhaul. Still very happy.

K
Kurt
Good value for smart ring tech

Smart rings from big brands cost 3x this price. This one performs at 90% of the functionality. For the casual health tracker it's an easy recommendation.

R
Ronald
Works for my use case

I just wanted sleep and step tracking — this ring does both well. I don't use all the features but what I do use is reliable and accurate.

FAQs

Category

Ring-based optical sensors are generally considered more accurate than wrist-based ones due to closer proximity to blood vessels. All consumer-grade sleep trackers provide estimates, not clinical measurements. The data is most useful for identifying patterns over time rather than precise nightly readings.

Battery capacity is 18mAh. Exact runtime depends on usage and feature settings, particularly how often real-time monitoring is active. Charge in the case when the app indicates a low battery.

The ring collects data passively. Viewing and analyzing that data requires the companion app and a Bluetooth-connected smartphone.

Measure the circumference of your finger in millimeters and compare to a standard ring size chart. Fit matters for both comfort and sensor performance. When in doubt, size up rather than down.
