Wellue O2Ring Oxygen Monitor 24/7 📟

This slim wearable ring monitors blood oxygen saturation and pulse rate throughout the day, helping athletes and frequent flyers track their oxygen levels during activity or altitude exposure. It records continuous SpO2 and pulse data and sends vibration alerts when readings cross preset thresholds, making it useful for overnight or extended monitoring.

Key Points

The device runs automatically when worn and uses a soft silicone sensor that fits adult fingers with a perimeter of about 2.17 to 3.15 inches. According to the manufacturer, it supports continuous tracking for long periods and includes motion detection to correlate activity with oxygen and pulse trends. The unit stores data locally and uploads it to the app when connected, so you can review sessions without having to stay paired the whole time. Note that the product is intended for sports and aviation use and is not a medical device, which may matter if you need clinical-grade readings. 🏃♂️📈

Benefits

Battery life allows extended use between charges, so you can monitor sleep or multi-hour activities without frequent recharging. The vibration reminder is adjustable and helps flag low oxygen or out-of-range heart rate events immediately. App and PC reports provide visual trends and exportable PDF or CSV files for sharing or personal records. Consider that the ring stores up to four groups of 10-hour data internally, which reduces the risk of losing short-term recordings if your phone is unavailable. Also keep in mind that accuracy can vary with movement and fit, so a snug positioning is important for consistent readings. 🔋
