Now you can access your most important information at your fingertips. The Colmi R03 smart ring provides convenient access to health and workout reports from the QRing app. What's more, it is resistant to water (5ATM), corrosion and wear and tear, so you can use it comfortably on a daily basis. The included case will allow you to safely store the ring and renew its energy. In addition, the lightweight (4.7g) design translates into comfort.
Monitor your health status
Colmi R03 will allow you to take care of your health. Smartring monitors sleep, its phases and quality, so you can eliminate bad habits. In addition, it measures your heart rate before 24 hours, which will allow you to understand the state of your body both at rest and during exercise. You can also measure your blood oxygen levels, and check all your health information in the dedicated QRing app.
Increase the effectiveness of your workouts
Exercise more efficiently with the Colmi R03. The smart ring accurately records data on the number of steps, calories burned and distance traveled. In addition, you can choose from 21 sports modes. What's more, the smartring is 5ATM water resistant, which means you can use it during intense workouts and swimming without worrying about damage.
Dedicated app
Download the Android- and iOS-compatible QRing app and use the Colmi R03 to its full potential. From its level you can keep an eye on all parameters and physical activity. It generates daily, weekly and monthly reports of your measurements, so you can quickly respond to any irregularities.
Long working time
Use the Colmi R03 for several days without worrying about discharge. The smart ring works for about 5-7 days, and it will take about 1 h to charge. In turn, the included case not only makes it easy to store, but also allows you to charge the device. Its powerful battery allows the ring to renew its energy up to 13 times on a single charge.
