The Diesel Ultrahuman Ring employs an array of sensors, including a temperature sensor, a PPG (photoplethysmography) sensor, and a motion-sensing IMU (inertial measurement unit). By capturing signals from your finger, these sensors enable the ring to collect vital data. These signals are then processed using advanced algorithms, developed by Ultrahuman, to provide you with profound metabolic insights and a comprehensive understanding of your body's dynamics.

Heart Rate Variability, commonly abbreviated as HRV, refers to the extent of fluctuation or variation in your heart rate over a specific timeframe. HRV serves as a valuable metric for assessing physical well-being, including heart conditions, as well as mental health factors such as anxiety and stress levels. Generally, a higher HRV is regarded as an indication of better overall health.

The Diesel Ultrahuman Ring operates seamlessly with the existing functionalities within the ring section of the app. Should there be the introduction of new features, rest assured they will be made available for the Diesel Ultrahuman Ring, Ultrahuman Ring AIR, and the Ultrahuman Ring (R1).

The Diesel Ultrahuman Ring is capable of tracking a comprehensive range of metrics associated with Sleep, Movement, and Recovery. This includes Heart Rate, HRV, Body Temperature, SPO2, Sleep Stages, Movement Frequency, and Recovery patterns, among others. Additionally, it offers real-time insights designed to guide you towards making healthier daily decisions. These metrics are also seamlessly integrated with the broader Ultrahuman ecosystem of products, such as the Ultrahuman M1.

The Diesel Ultrahuman Ring and Ultrahuman M1 work in synergy to provide valuable insights into your metabolic health. By combining glucose data from the M1 with data on movement, sleep, and body metrics collected by the ring, deep correlations can be established. This helps us identify how certain foods impact glucose levels, allowing for proactive recommendations on activities or interventions to counter or assist these effects. The integration of M1 and Ring data empowers us to offer personalized and precise insights tailored to your unique metabolic health needs.

By leveraging the combined data on Sleep and Glucose, we can analyze in real-time how glucose spikes impact your sleep. For example, if higher-than-usual glucose spikes occur after a meal, it may be correlated with poor sleep quality. Real-time nudges will help you take appropriate actions to assist the situation.
