The Diesel Ultrahuman Ring offers a range of health-tracking features, including sleep tracking, heart rate monitoring, step counting, calorie tracking, and real-time stress and recovery insights. Ultrahuman also says the ring can monitor blood caffeine levels, giving users an idea of when they should stop consuming caffeine during the day. In addition, the wearable supports ovulation cycle tracking for female users.
For sensors, the smart ring includes an infrared photoplethysmography (PPG) sensor, a medical-grade skin temperature sensor, six-axis motion sensors, red LEDs for heart rate and oxygen saturation tracking, and green and infrared LEDs for heart rate monitoring.
The ring supports Bluetooth Low Energy 5 and is compatible with iPhones running iOS 15 or later, as well as Android devices running Android 6 or newer. Ultrahuman claims the ring can deliver between four to six days of battery life. It packs a 24mAh battery and takes around 180 minutes to charge from zero to full using the included base charger, which connects via a USB Type-C cable.
In terms of size and weight, the smart ring measures 8.2mm in width and up to 4.2mm in thickness, while weighing up to 4.1 grams.
