ELENVA Smart Ring Health Tracker – 5ATM Waterproof, Sleep, SpO2, HRV, Cycle Prediction

Elevate your daily wellbeing with the ELENVA Smart Ring Health Tracker

Designed to be worn like a sleek ring, the ELENVA Health Tracker blends discreet style with serious sensing technology. It supports 24/7 monitoring of heart rate, SpO2, and body temperature, delivering data that can help you understand everyday patterns and how your body responds to activity, rest, and stress.

What it tracks and how you can use it

High-precision optical sensors measure heart rate, blood oxygen saturation (SpO2), and skin temperature with consistent results. Advanced HRV analysis provides daily mood insights, stress indicators, and fatigue signals. The sleep algorithm breaks the night into four stages—light, deep, REM, and awake—so you can spot trends in rest quality.

• Gentle ring vibrations plus phone alerts notify you if your heart rate crosses thresholds during workouts or rest.
• Exclusive vibration motor enables silent call alerts and discreet health warnings, with fingertip wake-ups and customizable reminders.
• Our tactile pulse alerts deliver vibrations for calls, health notes, schedules, medications, and daily reminders—without pulling you away from tasks.

Durability, comfort, and practicality

Crafted from marine-grade 316L stainless steel, the ring is built to handle 50m water pressure and wide temperature ranges (-20°C to 60°C). The 2.5mm sweat-resistant band is tested across diverse skin pH types, aiming for comfortable all-day wear.

• Water resistance supports active lifestyles and weather-ready wear.
• Robust materials ensure durability without sacrificing comfort.

Power, privacy, and data control

The energy-efficient ARM processor provides 2–5 days of use on a 90-minute magnetic charge. You can export RAW biometric data (CSV/JSON) to Strava or Apple Health via the iOS 14+ / Android 8+ app with Bluetooth 5.1. All ring data can stay stored locally on your device, with step counts able to sync to Apple Health and Google Fit.

• Local data storage helps you control your information while keeping insights at hand.
• Multi-platform compatibility supports your existing health and activity apps.

Activity awareness and cycle insights

An AI algorithm tracks basal body temperature (BBT) to predict cycles and ovulation with 95% accuracy. The ring automatically detects and records 10+ activities—running, yoga, swimming, and more—while measuring calories, steps, and distance. Post-activity HRV analysis can suggest optimal rest periods.

All this combines into a thoughtfully designed wearable that aims to support your routines with data-driven prompts, without overpromising results. Use it to explore patterns, plan workouts, and stay connected in a quiet, unobtrusive way.
