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.
Does it come with a charger?
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.

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.

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.
