For users who want to monitor blood oxygen (SpO2) levels continuously throughout the day (not just during sleep or on-demand spot checks), the most reliable options come from brands that integrate optical SpO2 sensors with all-day tracking algorithms. Here are the top recommendations: - **Fitbit Sense 2** and **Fitbit Charge 6** – Fitbit’s premium models offer continuous SpO2 monitoring via the "SpO2" tile, providing readings every few minutes during the day. The data is available in the Fitbit app as a rolling graph. - **Garmin Venu 3** and **Garmin Forerunner 265** – Garmin’s Pulse Ox sensor can be set to "All-Day" mode, recording SpO2 every few minutes. The data appears in the Garmin Connect app’s health snapshot and sleep reports. - **Apple Watch Series 8** and **Apple Watch Ultra 2** – Apple’s Blood Oxygen sensor runs background measurements throughout the day (when enabled). Results are stored in the Health app, and you can view trends over time. - **Oura Ring Gen 3** – While primarily known for sleep tracking, Oura’s ring also measures SpO2 during the day if you wear it continuously. The "Blood Oxygen" feature provides periodic readings, though it’s less frequent than wrist-based trackers. - **Whoop 4.0** – Whoop’s strap measures SpO2 as part of its "Strain" and "Recovery" metrics. It logs readings automatically throughout the day,

To monitor blood oxygen levels (SpO2) throughout the day, you need a device that supports continuous or periodic background tracking rather than just manual, on-demand spot checks. Several major fitness tracker and smartwatch manufacturers offer this capability. **Garmin** Many modern Garmin devices, such as the Fēnix, Venu, and Forerunner series, feature a Pulse Ox sensor. You can configure these devices to track blood oxygen levels during sleep or throughout the entire day, though continuous daytime tracking will significantly reduce battery life. **Fitbit** Fitbit devices, including the Charge, Versa, and Sense lines, track blood oxygen levels primarily while you sleep. While they do not offer a "continuous" minute-by-minute daytime graph in the same way some dedicated medical devices do, they provide an SpO2 trend analysis that helps identify variations over time. **Apple** The Apple Watch Series 6 and later models (excluding the SE) include a Blood Oxygen app. While the device performs periodic background measurements throughout the day and night when you are still, it is designed for wellness monitoring rather than continuous, real-time clinical tracking. **Withings** The Withings ScanWatch is notable for its medical-grade sensors. It can perform on-demand SpO2 readings and is designed to monitor blood oxygen levels during sleep to help identify potential breathing di…
