The Ultrahuman Ring AIR is fortified with a robust Tungsten carbide coating, affording it a high degree of resilience against daily wear and tear. Despite this, we advise against wearing your ring during intense weight training sessions or while handling heavy metal objects. Even repeated contact with relatively less hard substances can potentially leave a mark on the ring.

Indeed! The Ultrahuman Ring AIR boasts a water resistance rating that extends up to 100 meters, permitting wear during activities like swimming, showering, scuba diving and more. To maintain its optimal performance, we advise against keeping the ring submerged for periods exceeding 12 hours continuously.

With comprehensive fitness, movement, and wellbeing tracking, the Ultrahuman ring is absolutely worth it! The Ultrahuman team are always adding new features and upgrading firmware, and are available 24/7 for support queries.

The Ultrahuman Ring is meant for providing accurate insights into sleep, recovery, and movement, but it’s important to note that it is not a medical device and shouldn’t replace clinical-grade equipment for critical monitoring.

The Ultrahuman Ring AIR typically requires a one-time calibration period of up to 7 days. Subsequent calibrations will only be necessary if the ring undergoes a hard reset.

The Ultrahuman Ring AIR operates as a low-power device that communicates with your smartphone using Bluetooth Low Energy (BLE) technology. It establishes a connection with the smartphone only when you open the Ultrahuman App or at regular time intervals, unlike Bluetooth headsets, earbuds, or smartwatches that maintain constant connectivity and data transmission/reception. It's important to note that Bluetooth activity for the Ultrahuman Ring AIR remains below 1% throughout the day, resulting in significantly lower EMF radiation compared to other Bluetooth wearables. Consequently, the Ultrahuman Ring AIR can be regarded as one of the safest wearable devices for fitness tracking in terms of EMF exposure.

Absolutely! The Ultrahuman Ring AIR is designed to be ESD-safe, ensuring that you will not experience any electrostatic shocks from the ring.
