HOW IT FITS
Halo Ring 3 fits more snug due to raised sensors on the inside. Consider swelling and knuckle width when choosing your fit.
→ Our recommendation: go one size up
For the best fit, we recommend sizing up by one size from your usual ring size, based on the finger you plan to wear your Halo Ring on.
Halo Ring is best worn on the index finger, which typically requires a slightly larger size than other fingers. Sizing up helps ensure comfort, accurate tracking, and all-day wear.
Yes, HALO Ring comes with a USB charging cable included with every order.
We also offer an optional wireless fast charging case, which is recommended for quicker charging and convenient on-the-go use.

Lifetime Warranty (Optional Upgrade)

See Why It’s Rated 4.7★
I honestly didn’t think I’d wear this every day but I do. It’s super light and doesn’t look like tech, which I love. My sleep score actually helped me fix my bedtime routine.
I love how minimal it looks. I do wish battery life was maybe a little longer, but it still lasts several days and charges fast.
Cycle tracking + sleep tracking in one place is exactly what I wanted. It’s been super helpful for understanding my energy throughout the month.
I forget I’m even wearing it. It doesn’t feel bulky at all and it’s cute enough to match my jewelry
Really impressed so far. It tracks everything I need and I like that there’s no subscription. The app took me a day to get used to but after that it’s been great.
Super lightweight and doesn’t scream “fitness tracker.” That was important to me. It just looks like a normal ring.
Love it so far. The app is clean and easy to read. Took a few nights to fully start tracking sleep but now it works consistently.
It’s cute AND useful which is rare for tech. I wear it to work, to the gym, everywhere.
Great value for what it tracks. I mainly use it for sleep and steps and it’s been very accurate.
Love it so far. The app is clean and easy to read. Took a few nights to fully start tracking sleep but now it works consistently.
I stopped wearing my Apple Watch after a week of having this. It’s way more comfortable and I don’t feel like I’m constantly being notified.
The stress tracking lines up perfectly with my work schedule 😅 I didn’t realize how tense I was until I saw the data.
Great ring overall. It’s comfortable and accurate. I sized up like recommended and it fits perfectly.
My boyfriend got this for me and now I’m obsessed. I check my sleep score before I check Instagram.
very impressed with the data. I just wish there were a few more color options, but performance-wise it’s solid.
This helped me realize why I was crashing every afternoon. Now I actually plan my workouts around my recovery score
Love it so far. The app is clean and easy to read. Took a few nights to fully start tracking sleep but now it works consistently.
I didn’t realize how much my sleep affected my mood until I started tracking it. Definitely one of those purchases I’m glad I made
the HRV and stress insights are actually useful. I’ve started taking recovery more seriously because of it.
Overall really happy with it. It does everything advertised. Just make sure you size correctly and you’ll love it.
