prxxhri Smart Health Ring Silver Size 7 — Waterproof Fitness Tracker for Women & Men, Sleep & Stress Monitoring

The prxxhri Smart Health Ring is a small, wearable tracker that records sleep patterns, stress indicators, heart rate, and daily activity without a subscription.

Compact and designed for all-day wear, this silver size 7 ring combines motion and optical sensors to deliver continuous health and fitness insights to iOS and Android devices. It pairs with a free app to display sleep stages, step counts, calorie estimates, and regular heart-rate checks, and it’s built to withstand water exposure for exercise or swim sessions. The ring’s short charging interval and optional charging case extend usage so you can monitor trends without frequent stops for power.

How does the ring track sleep and help me understand my rest?

The prxxhri ring uses onboard sensors to detect movement and heart-rate variability, translating that data into sleep stages and duration. It presents easy-to-read summaries in the companion app so you can spot patterns and make small changes to improve nightly recovery. It does not provide medical diagnoses but gives consistent, comparable measurements night to night.

• Automatic detection of sleep start and end times
• Breakdown of light, deep, and REM periods
• Nightly score and trends over time for comparison

Will it survive workouts, showers, and swimming?

Yes — the ring is rated to 80 meters of water resistance, so it tolerates showers, pool swims, and sweat-heavy gym sessions. The durable casing and skin-friendly materials are intended for continuous wear, so you can leave it on during most daily activities. Rinse and dry after exposure to chlorine or saltwater to maintain the finish.

• 80-meter waterproof rating suitable for swimming and showering
• Corrosion-resistant finish for regular wear
• Comfortable fit for prolonged use, including exercise

How long does the battery last, and what about charging?

On a single charge, expect roughly 2–3 days of continuous monitoring depending on usage intensity and sampling intervals. The included charging case can extend total runtime past 10 days, making multi-day trips and weekend getaways simpler. Charging is straightforward and the ring quickly returns to active tracking so you won’t miss many hours of data.

• 2–3 days typical battery life per charge
• Optional smart charging case extends use beyond 10 days
• Fast recharge cycles to minimize downtime

What health metrics does it record and is there any ongoing cost?

The device measures heart rate regularly (automatic checks every 30 minutes while worn), step count, calories burned, and sleep metrics, along with a stress-related indicator derived from heart-rate patterns. All features are available without app-subscription fees; you get full access to collected data at no extra cost. Data stays viewable in the app and can be reviewed over days and weeks to reveal trends.

• Automatic heart-rate sampling every 30 minutes
• Step, calorie, and activity tracking throughout the day
• No subscription required for app features or data access

Who is this for: The prxxhri Smart Health Ring is aimed at people who want discreet, continuous tracking in a jewelry-style device — active swimmers, gym users, shift workers, and anyone curious about sleep and daily activity trends without paying subscription fees. Check the size chart before purchasing to ensure a comfortable fit; the ring is particularly suited to buyers who prefer minimal interruption from charging and value waterproof durability and straightforward, private data access.
