***Special Notice for Apple Watch Models Sold in the United States: This App operates strictly as a standalone watch application. Due to recent patent litigation and subsequent Apple official firmware adjustments, certain Apple Watch models (such as Series 9, 10, Ultra 2, and subsequent models) sold in the United States after January 2024 have system-level restrictions that disable the generation and synchronization of local blood oxygen data. Consequently, users with these US-region models will not be able to read or display blood oxygen data on the watch after downloading the app. Please note that this is not a software defect. Users who own the aforementioned restricted US-model devices are strongly advised to exercise caution before downloading or purchasing. We sincerely apologize for any inconvenience caused. ***For US Apple Watch users, you can download the iPhone companion app version to sync blood oxygen information from your phone. Please uninstall this standalone watch app before using the iPhone companion app version. Core Highlights Two Metrics in One, At a Glance - Dual Display: Seamless integration of Heart Rate and SpO₂.
