TYUIOL Smart Ring Fitness Tracker — Heart Rate & SpO2

The TYUIOL Smart Ring is a compact, waterproof fitness and health tracker ring that monitors heart rate, blood oxygen, sleep, steps and activity without any subscription fees.

This slim silver ring (size 9) blends everyday wearability with continuous biometric and activity tracking for iOS and Android phones. It records heart-rate trends, blood oxygen levels, sleep stages and movement metrics, syncs to a companion app, and is built for regular use with an IP68 rating so you can wear it through handwashing and light swimming.

How does the TYUIOL ring track daily activity?

The ring uses built-in motion sensors and step counting algorithms to log steps, distance, calories and active minutes throughout your day. It auto-detects many types of movement and stores session summaries that sync to your phone for review.

• Accurate step counting and distance estimates for walking or running
• Calorie and activity time calculations to monitor daily energy use
• Automatic activity detection for common exercises like cycling and yoga

What health metrics does it measure and how often?

TYUIOL continuously records heart rate and can take on-demand readings for blood oxygen and blood pressure indicators through optical sensors. Sleep is automatically tracked each night, breaking down deep, light and awake periods so you can spot patterns over time.

• Continuous heart-rate monitoring with trend graphs in the app
• SpO2 (blood oxygen) and blood pressure readings available on demand
• Automatic sleep-stage detection with nightly summaries and duration details

Will it work with my phone and do I need a subscription?

The ring pairs with both iOS and Android via its companion app for setup, data sync and viewing historical metrics. There is no recurring subscription required to use the core tracking features or to access your activity and health history.

• Compatible with modern iOS and Android devices through Bluetooth
• No subscription fees for core functionality and data access
• Simple app interface for reviewing trends, exporting data, and configuring alerts

Is the ring durable enough for everyday life?

Designed for daily wear, the TYUIOL ring is IP68-rated, meaning it tolerates handwashing, showers and brief shallow swimming sessions. Its metal finish resists everyday wear, while the device remains lightweight and unobtrusive for all-day comfort.

• IP68 waterproof rating for water exposure and sweat resistance
• Lightweight metal construction for durability and comfort
• Discrete silver finish suitable for work, gym, and social settings

Who is this for: The TYUIOL Smart Ring is a good fit for anyone who wants a low-profile wearable for continuous health and activity insights without phone‑dependent charging or subscription costs. It suits busy professionals, active hobbyists, and those starting to track sleep and biometric trends who prefer a ring over a wrist wearable. Choose the silver size 9 if that matches your finger size and you want a waterproof, everyday tracker that syncs with iOS or Android.
