This lightweight and comfortable pulse oximeter ring is designed to fit most adult fingers (1.57–2.36 inches) and can be worn continuously during sleep, exercise, or daily activities. Equipped with newly upgraded chips for up to 1% improved accuracy, it tracks blood oxygen levels, pulse rate, and body movement in real time, displaying data directly on the ring and syncing seamlessly with the mobile app. Made from soft, low-sensitivity silicone, the ergonomic design ensures a breathable, barely noticeable fit that won’t disturb your rest. For best results, wear it on the fingertip rather than over the bone.
Featuring convenient USB-C charging, the device provides up to 10 hours of continuous use on a full charge. Simply turn on Bluetooth and open the app for automatic connection—its rotatable display supports both left- and right-handed wear. The feature-rich app allows multi-user storage, detailed data tracking, downloadable reports, and customizable alerts for abnormal readings. It also works offline, keeps your personal data private, and offers unlimited in-app storage. During Bluetooth disconnection, the ring can store up to 21 hours of data and automatically sync once reconnected. Designed for sports and aviation use only, not intended for medical purposes.
