Didn’t expect it to be this accurate honestly, especially compared to larger fitness devices. It’s really comfortable to wear, especially for sleep, and the app is easy to understand. I’ve already started improving my sleep because of it.

I bought this mainly for my sleep and it’s honestly been eye opening. I didn’t realize how broken my sleep actually was until I started tracking it. After a few days of adjusting my routine, I’m already feeling more rested.

I’ve tried other trackers before but I could never sleep with them on. This is the first one I actually forget I’m wearing. Way more comfortable and the data still feels just as accurate.

Super easy to use and the app makes everything really clear. I like that I can just wear it all day and not think about it. Definitely helped me start paying attention to my sleep more.

How to Find Your Perfect Fit

Our rings are true to size with US ring sizes!

Getting the right size is quick and easy no special tools needed!

METHOD 1: Measure Your Finger (Perimeter Method)

STEP ①
Cut a thin strip of paper or tape and wrap it snugly around the base of your finger. Mark the point where it overlaps with a pen or pencil.

STEP ②
Straighten the strip and measure its length with a ruler. Match your measurement to the sizing below.

Size 5 → 54-56 mm
Size 6 → 57-59 mm
Size 7 → 60-62 mm
Size 8 → 63-64 mm
Size 9 → 65-67 mm
Size 10 → 68-70 mm
Size 11 → 71-73 mm
Size 12 → 74-76 mm:
Size 13 → 76-78 mm:

NOTE: The measurements shown are finger perimeters, taken by wrapping paper or tape around the base of your finger. These numbers may be slightly different from official US ring circumferences because they reflect the practical way your finger is measured, not the exact inner circumference of the metal ring.

Pro Tip: If you're between sizes, choose the size which is closest to your measurement especially if you plan to wear your smart ring all day.

METHOD 2: Match with an Existing Ring (Diameter Method)

Step 1:
Find a ring that already fits the finger you’ll wear your smart ring on.

Step 2:
Use a ruler or measuring tape to measure the inner diameter of that ring in millimeters straight across the center.

Match it to the sizing below:

Size 5 → 15.7 mm
Size 6 → 16.5 mm
Size 7 → 17.3 mm
Size 8 → 18.2 mm
Size 9 → 18.9 mm
Size 10 → 19.8 mm
Size 11 → 20.6 mm
Size 12 → 21.3 mm
Size 13 → 22.2 mm

Tip:
Measuring a flat ring on a hard surface gives the most accurate results.
