What's New in Halo Sense?

Halo Sense is our slimmest and most comfortable smart ring so far. It's 40% lighter and slimmer than Halo Sense 3, so it feels even more like everyday jewelry.

We've also upgraded the internal sensors and tracking technology to deliver improved accuracy for sleep, heart rate, stress, and overall wellness insights—while maintaining the same long-lasting comfort you expect from Halo.

Halo Sense 3 remains part of our lineup and is still available for purchase in select styles, including our Flat Top and Concave designs. While Halo Sense introduces a lighter, slimmer profile with upgraded internal tracking technology, Halo Sense 3 continues to offer the same core wellness tracking experience in the signature styles many of our customers already love.

Whether you like the newest Halo Sense or the distinctive look of Halo Sense 3, pick the design that suits your style.

Getting the right size is one of the most important parts of owning Halo Sense.

Unlike traditional jewelry, Halo Sense contains advanced sensors that require a secure fit to provide accurate wellness tracking. Your ring should feel snug, but comfortable—tight enough that it won't rotate freely, but loose enough to remove without discomfort.

Should I Size Up?

In most cases, no.

Halo Sense is manufactured using standard US ring sizes, so if you already know your US ring size, we recommend ordering your normal size.

However, because Halo Sense is wider than a traditional ring (approximately 7–8.5mm depending on the model), it may feel slightly tighter than a thin jewelry band.

We recommend sizing up only if:

• You're between two ring sizes.
• You prefer a looser fit.
• Your fingers tend to swell throughout the day.

If your normal ring already fits snugly, stick with your usual US size.

Best Finger Placement

For the most accurate readings, we recommend wearing Halo Sense on your:

✅ Index Finger (Recommended)

You can also wear it on your:

• Middle Finger
• Ring Finger
• Thumb (if comfortable)

Avoid wearing Halo Sense on your pinky finger whenever possible, as sensor accuracy may be reduced.

Between Two Sizes?

✔️ Choose the smaller size if:

• You want the most accurate tracking.
• Your fingers rarely swell.
• You prefer a secure fit.

✔️ Choose the larger size if:

• Your fingers swell often.
• You plan to wear Halo Sense all day and overnight.
• You're between sizes.

Standard 30-Day Warranty (Included)

Every Halo Sense comes with a 30-day warranty that covers manufacturing defects and hardware issues under normal use.

Lifetime Warranty (Optional Upgrade)

Our Lifetime Warranty provides extended peace of mind and covers your Halo Sense beyond the initial 30 days, including protection against defects and functional issues for as long as you own the ring. This option is recommended for long-term wear and daily use.

The SenseCare+ Lifetime Warranty provides extended protection beyond the standard 30-day warranty and includes:

• Coverage for manufacturing defects for the lifetime of the product
• Hardware malfunctions under normal, intended use
• Functional failures related to internal components
• Replacement support if the ring stops functioning due to covered issues
• Priority warranty assistance through our support team
