prxxhri Smart Health Ring waterproof fitness tracker for men & women — Dull Silver, size 11, sleep & stress monitoring

prxxhri Smart Health Ring is a compact, waterproof wearable that monitors sleep, stress indicators, heart rate and daily activity without any subscription fees.

The prxxhri Smart Health Ring combines discreet design with continuous biometric tracking so you can review sleep stages, heart rate trends, and activity metrics on iOS or Android. Lightweight and water-resistant to 80 meters, this ring is designed for everyday wear and athletic use. It uses built-in sensors to capture data automatically and stores or transmits results to the companion app for review—no ongoing subscription required.

How accurate is the prxxhri ring for sleep and fitness tracking?

The ring uses advanced optical sensors to measure heart rate and motion patterns, then interprets those signals into sleep stages and activity summaries. While it's optimized for consistent wrist-adjacent wear on a finger, results are best used as personal trends rather than clinical measurements.

• Continuous heart-rate sampling every 30 minutes while worn
• Automatic sleep stage detection (light, deep, REM) from motion and pulse
• Step, calorie and basic activity recognition with daily summaries
• Data viewable in the prxxhri app on iOS and Android

How long does the battery last and what charging options are available?

Typical on-device battery life runs 2–3 days on a full charge, depending on tracking intensity and sensor use. Pairing the ring with its smart charging case extends total usage beyond 10 days, making it convenient for travel or periods when recharging is less frequent.

• 2–3 days per single ring charge under normal use
• Smart charging case provides over 10 days of combined runtime
• Easy dock-style charging—no subscription or cloud fees needed
• Battery indicators available in the companion app

Is the prxxhri ring durable enough for swimming and active lifestyles?

The ring is rated to 80 meters waterproof, so it handles showers, swimming, and most water-based workouts with confidence. Its metal finish and smooth profile also reduce snagging during exercise, and the hypoallergenic fit is intended for comfortable long-term wear.

• 80-meter waterproof rating suitable for swimming and diving
• Dull silver finish resists everyday wear and sweat
• Designed to be lightweight and low-profile for sports
• Comfortable for all-day and overnight use, including sensitive skin

What setup and compatibility should I expect with my phone?

Setup involves installing the prxxhri companion app on iOS or Android and pairing the ring via Bluetooth. The app displays historical trends, live stats while worn, and settings—without requiring any paid subscriptions or in-app fees.

• Compatible with most modern iOS and Android devices via Bluetooth
• No subscription: all features unlocked after pairing
• In-app dashboards for sleep, heart rate, steps and calories
• Firmware updates and battery status delivered through the app

Who is this for? The prxxhri Smart Health Ring suits people who want a low-profile, always-on tracker that focuses on daily wellness and sleep trends rather than clinical diagnostics. It's a good match for athletes and casual exercisers who need waterproof durability, travelers who value extended battery life with a charging case, and anyone who prefers a subscription-free device for continuous monitoring. Before ordering, consult the size chart and measure finger circumference carefully to ensure a comfortable fit and secure data tracking.
