Halo Ring — Smart Health Tracker for Sleep, Heart Rate & Activity

Wellness that doesn't shout

Most fitness trackers demand your attention. The Halo Ring just quietly does its job.

Slip it on and it tracks your heart rate, sleep stages, and daily movement around the clock — no notifications buzzing your wrist, no screen pulling you back into your phone. You check in when you want to, not when a device decides you should.

What it tracks

• Heart rate — continuous monitoring, day and night
• Sleep — total duration plus light, deep, and REM breakdown
• Activity — steps, distance, and calories burned
• Recovery trends — see how well you're bouncing back over time

Built to disappear

Machined from durable alloy with a smooth interior finish, the Halo Ring weighs less than most wedding bands. IP68 water resistance means showers, dishes, and rain are non-issues. Bluetooth syncs to the free companion app in seconds.

Not sure on size?

Most men wear a 10–12; most women wear a 7–9. If you already know your ring size, order that. If you don't, measure the finger you plan to wear it on at the end of the day, when fingers run slightly larger.
