IOS operating system

When fully charged, the ring is designed to operate for approximately up to 6 days under standard usage conditions. However, specific factors such as battery lifespan, environmental temperature, and frequency of use can influence this duration. You can anticipate approximately 500 charging cycles before there is any significant decline in battery performance. As is common with all battery-powered devices, a gradual reduction in battery life can be expected after 1 to 2 years.

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 Ultrahuman Ring predicts your ovulation and fertile window by analysing key biometrics: skin temperature, heart rate variability (HRV), and resting heart rate (RHR). It uses historical data from your previous cycles to identify patterns and combines this with real-time biomarker tracking to adjust predictions as your cycle progresses. To use this feature, you must activate PowerPlugs.

To activate PowerPlugs on the Ultrahuman App, you can tap the "Activate more PowerPlugs" icon on the ring homepage. You can then browse the available options and tap "Get" next to the PowerPlug you want. You will then be redirected to the app store to make your purchase in case it is a premium PowerPlug.
