CIRCUL is a free iPhone application developed by Bodimetrics LLC. It falls under the category of Utilities & Tools and is designed to work in conjunction with the circul+ device. This app aims to help users monitor peripheral oxygen saturation, heart rate, and other health metrics, while also generating detailed health reports and analysis.

With CIRCUL, users can easily connect their circul+ device to their iPhone via Bluetooth. The app offers three types of monitoring: daily monitoring, operation monitoring, and sleep monitoring. The latest circul+ ring even has the ability to monitor blood pressure. Users can simply tap to turn monitoring on or off and the app will automatically generate reports based on the collected data.

This comprehensive health monitoring app tracks various health metrics including oxygen saturation, sleep patterns, body temperature, heart rate variability (SDNN), diastolic and systolic blood pressure, resting heart rate, and heart rate data from the circul+ ring. All this data is seamlessly saved to Apple Health in real-time. Additionally, the app supports daily step counting and can access data from Apple Health, allowing users to switch between the circul+ ring and Apple Health as the source of steps.

It is important to note that while CIRCUL provides valuable health information, it should not be used as the sole basis for making medical decisions. Users are advised to consult their doctor for professional advice in addition to using this application.
