R04 Smart Ring: Heart rate variability monitoring
Designed for the health-conscious individual who wants continuous wellness insights without the bulk of a wristband, the R04 Smart Ring fits seamlessly into your daily routine. Wear it while working, sleeping, or exercising to monitor key metrics like heart rate variability, body temperature, and sleep stages.
Unlike bulky fitness trackers, this ring stays out of the way. You’ll forget it’s there until the subtle vibration reminds you to stand up after a long meeting. The sensor picks up your pulse while you’re typing an email, giving you real-time stress readings. By tracking body temperature trends, it can alert you to early signs of illness before you feel symptoms.
With multi-sport modes and stainless steel durability, the R04 supports your active lifestyle. The accompanying app turns raw data into actionable insights, like adjusting your bedtime when HRV dips. It’s a personal health companion that works quietly in the background—so you can focus on living.
