Halo Ring 4
Every metric. No subscription.
BEFORE YOU BUY
Looking us up first? Here's the straight version.
You should be skeptical of a $59 smart ring. These are the questions people ask before they buy, answered plainly.
Why is Halo cheaper when other smart rings cost $300 or more?
No subscription and no retail markup. We sell direct, and the app stays free for as long as you own the ring. You are paying for the ring, not a monthly fee or a marketing budget.
Is the tracking accurate?
Halo reads your sleep, heart rate, HRV, stress and activity overnight and through the day, and turns them into wellness insights, not medical readings. Like every smart ring, it reads best when it fits snugly, so use the AI size finder or the sizing guide before you order.
Is there a subscription for HALO Ring?
No — HALO Ring does not require a subscription.
All features are included with your purchase, and the HALO app is completely free to use. You’ll have full access to health insights, tracking, and updates with no monthly fees or hidden costs.
You pay once for just the ring and enjoy lifetime access.
How long does shipping really take?
Processing: 1 to 2 working days. Shipping: 7 to 10 working days. You get a tracking number by email the moment it ships.
Not happy with it? You have 30 days to return it.
What if it doesn't fit, or I don't love it?
Wear it for 30 nights. If it isn't right for you, send it back for a full refund. Wrong size? Message support and we will help you swap it.
What comes with HaloCare+ Lifetime Warranty
Standard 30-Day Warranty (Included)
Every HALO Ring 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 Ring 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 HALO 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
What's covered if something goes wrong?
Every ring includes a 30-day warranty against manufacturing defects and hardware issues. HaloCare+ extends that to lifetime coverage. If your ring ever stops charging or syncing, open a warranty claim and our team takes it from there.
Sizing Guide
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.
Halo Ring 4 vs Halo Ring 3
What's New in Halo 4?
Halo 4 is our thinnest and most comfortable smart ring yet. It's 40% lighter and slimmer than Halo 3, making it feel 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 3 remains part of our lineup and is still available for purchase in select styles, including our Flat Top and Concave designs. While Halo 4 introduces a lighter, slimmer profile with upgraded internal tracking technology, Halo 3 continues to offer the same core wellness tracking experience in the signature styles many of our customers already love.
Whether you prefer the latest Halo 4 or the distinctive look of Halo 3, you can choose the design that best fits your style.
