Our NEXTRING is available in three colours: Raw Titanium, Matt Black, & Rose Gold.

Our NEXTRING works with iPhones running iOS 15 or later and with Android devices running Android 6 or later.

The ring is carefully crafted from durable titanium and reinforced with a tungsten carbide coating that increases its resistance to daily activities.

The NEXTRING has a range of sensors, including a temperature sensor, a PPG sensor (photoplethysmography) and an IMU (Inertial Measurement Unit) for measuring movement. These sensors detect the signals from your finger and enable the ring to collect vital data. These signals are then processed using advanced algorithms developed by NEXTRING to give you deep insights into your metabolism and a comprehensive understanding of your body's dynamics.

The Ring AIR is able to capture a comprehensive range of measurements related to sleep, movement and recovery. These include heart rate, HRV, body temperature, SPO2, sleep stages, movement frequency and recovery patterns. It also provides real-time insights to help you make healthier choices every day.

Heart rate variability, commonly abbreviated as HRV, refers to the amount of fluctuation or variation in your heart rate over a period of time. HRV is a valuable measure for assessing physical well-being, including heart disease, as well as mental health factors such as anxiety and stress levels. In general, a higher HRV is considered an indication of better overall health.

Unlike many other wearables, the NEXTRING focuses specifically on providing insights into factors that influence our body's metabolism. It goes beyond traditional tracking by measuring key aspects such as sleep quality, sleep zones, stress levels (through HRV) and activity distribution. What makes it special is its ability to not only collect data, but also correlate it with real-time prompts and insights so that users can make informed decisions to improve their metabolic health.

The measurements derived from the ring are carefully compared with industry-leading fitness wearables available worldwide.

Your data is hosted on our secure servers in EUROPE, which means that no health or profile data leaves the European zone or reaches ASIA!

Without a doubt! Our ring is made from hypoallergenic materials and is therefore suitable for constant wear around the clock.

Yes, of course! The NEXTRING is waterproof to a depth of 50 metres and can therefore be worn during activities such as swimming, showering, diving and more. To maintain its optimal performance, we do not recommend wearing the ring underwater for more than 12 hours continuously.

The NEXTRING takes about 2 hours to fully charge.

It should be noted that the size of your fingers and the ring may fluctuate throughout the day and under certain conditions, making the ring feel tight and possibly difficult to remove.
If you find that your ring is stuck, consider these strategies:

• Moisten your finger with cold water and a little soap and then try to carefully twist off the ring.
• If you put your hand up, the blood pressure in this area can be lowered, which may make it easier to remove the ring.
• If your finger has enlarged due to strenuous exercise or the intake of food and drink, it may be helpful to give it some time to return to its normal size
