Who We Are
HRV Zone is an independent resource dedicated to helping people understand and use heart rate variability for better health and performance.
We're not affiliated with any device manufacturer or app developer. Our reviews and recommendations are based on hands-on testing and real-world experience, not sponsorship deals.
Our Mission
Heart rate variability is one of the most powerful biomarkers available, yet it remains confusing and inaccessible for most people. We're here to change that.
Our goal is to provide: - Clear explanations of HRV science without the jargon - Honest reviews of devices and apps based on actual use - Practical guides for using HRV to improve your health - Unbiased comparisons to help you choose the right tools
Our Approach
Every device and app we review goes through real-world testing. We don't rely on spec sheets or press releases—we use these products ourselves before making recommendations.
We believe in transparency. When we include affiliate links, we clearly disclose them. Our recommendations are never influenced by potential commissions.
