As a health expert with years of experience evaluating wearable fitness technology, I am always searching for devices that seamlessly integrate into daily life while delivering actionable health insights. When I first heard about the Herz P1 Smart Ring, I was intrigued by its promise of advanced health tracking in a discreet, jewelry-like form.
Over the past month, I have worn the Herz P1 continuously—during work, workouts, sleep, and even in the shower—to test its capabilities, comfort, and real-world usefulness.
Here, I share my detailed experience with the Herz P1 Smart Ring, highlighting its features, accuracy, and overall value.

Unboxing and First Impressions
The Herz P1 arrived in a compact, elegant box, reminiscent of premium jewelry packaging. Inside, I found the ring itself, a magnetic charging dock, a USB charging cable, and a quick-start guide. The ring’s construction immediately impressed me: crafted from military-grade stainless steel, it felt both sturdy and lightweight. I opted for the Midnight Black finish, which looked sleek and understated—perfect for both professional and casual settings.
Design and Comfort
One of the most critical aspects of any wearable is comfort, especially for a device intended for 24/7 use. The Herz P1 excels here. Its minimalist, ergonomic design ensures that it sits snugly on the finger without pinching or causing discomfort, even during sleep or intense physical activity. Unlike bulkier smartwatches, the ring never caught on clothing or felt intrusive. I often forgot I was wearing it, which is the highest compliment I can give a wearable.
The ring is available in several finishes, including Silver Spark, Rose Gold, and Sunrise Gold, allowing users to match their personal style. Its IP68 water resistance rating meant I could wear it while washing hands, showering, and even during a swim, without worry.
Setup and App Experience
Setting up the Herz P1 was straightforward. After downloading the Herz Health app—available for both iOS and Android—I paired the ring via Bluetooth. The app guided me through calibration, including inputting basic health information and selecting my dominant hand. Within minutes, the ring began collecting and displaying data.
The Herz Health app is visually appealing and intuitive. The dashboard presents a comprehensive overview of daily metrics, including heart rate, steps, calories burned, sleep stages, and stress levels. Data syncs automatically when the ring is near my phone, and I appreciated that all features were available without a subscription—something increasingly rare in the wearables market.
Health Tracking Features
Heart Rate and HRV
The Herz P1’s optical sensors continuously monitor heart rate and heart rate variability (HRV). I compared its readings to those from a medical-grade chest strap and found the ring’s data to be impressively accurate, with only minor deviations during high-intensity exercise. The HRV tracking provided valuable insights into my recovery and stress levels, helping me optimize my training and rest days.
Blood Oxygen (SpO2)
Blood oxygen measurement is a feature I consider essential, especially for those interested in respiratory health or high-altitude activities. The Herz P1’s SpO2 readings were consistent with my fingertip pulse oximeter, and the app flagged any unusual drops, which could be useful for early detection of health issues.
Sleep Analysis
Sleep tracking is where the Herz P1 truly shines. The ring automatically detects when I fall asleep, tracking total sleep time, sleep efficiency, and detailed stages (REM, deep, light). The app’s sleep reports are easy to interpret, highlighting trends and offering tips to improve sleep hygiene. Over several weeks, I used this data to adjust my bedtime routine and saw measurable improvements in sleep quality.
Stress and Readiness Scores
Using a combination of HRV, heart rate, and temperature data, the Herz P1 calculates daily stress and readiness scores. These metrics helped me identify days when I was more susceptible to fatigue or illness, prompting me to adjust my workload or prioritize recovery. The readiness score, in particular, became a valuable tool for planning workouts and managing stress.
Activity Tracking
The ring tracks steps, calories burned, and distance traveled with reasonable accuracy. While it may not match the precision of GPS-enabled devices for running or cycling, it excels at monitoring general activity levels throughout the day. I found the inactivity reminders—delivered via subtle colored light signals—helpful for breaking up long periods of sitting.
Body Temperature and Menstrual Cycle
Continuous skin temperature monitoring is a unique feature that sets the Herz P1 apart from many competitors. It provided early warning of potential illness and helped me correlate temperature fluctuations with sleep and recovery. For users tracking menstrual cycles, the app offers additional insights, making it a well-rounded tool for holistic health management.
Battery Life and Charging
Battery life is a crucial consideration for any wearable. The Herz P1 consistently delivered 6–7 days of use per charge, even with all sensors active. The magnetic charging dock is compact and easy to use, fully recharging the ring in under two hours. This longevity meant I rarely had to worry about running out of power, even during travel or busy weeks.
Notifications and Smart Features
While the Herz P1 is primarily a health tracker, it offers basic smart features, including call, message, and reminder notifications via colored light signals. These are subtle and non-intrusive, ensuring that the ring remains focused on health rather than becoming a distraction. I appreciated this minimalist approach, which aligns with the ring’s discreet design philosophy.
Data Privacy and Offline Storage
A significant advantage of the Herz P1 is its approach to data privacy. All health data is stored offline on the ring and only synced to the app when connected. This feature, combined with the absence of a subscription model, reassured me that my personal health information was not being monetized or shared without consent.
Durability and Daily Use
Over a month of continuous wear, the Herz P1 showed no signs of wear or scratching. Its robust construction and water resistance made it suitable for all activities, from weightlifting to swimming. The ring’s durability and comfort make it a practical choice for anyone seeking a long-term health companion.
Limitations and Considerations
No device is perfect, and the Herz P1 is no exception. While its health metrics are generally accurate, it is not a medical device and should not replace professional medical advice. Some online discussions have noted that the Herz P1 is similar to other rebranded smart rings, such as the Colmi R02, and there have been criticisms of marketing claims. However, in my experience, the ring delivered on its core promises and provided reliable, actionable health data.
Final Verdict: Is the Herz P1 Smart Ring Worth Buying?
After a month of rigorous testing, I can confidently say that the Herz P1 Smart Ring exceeded my expectations. Its combination of advanced health tracking, stylish design, and comfort make it a standout in the crowded wearables market. The absence of subscription fees, robust battery life, and commitment to data privacy further enhance its appeal.
For anyone seeking a discreet, comprehensive health tracker that fits seamlessly into daily life, the Herz P1 is an excellent choice. Whether you are a fitness enthusiast, a busy professional, or simply someone interested in optimizing your well-being, this smart ring offers genuine value. Based on my experience as a health expert, I believe the Herz P1 Smart Ring is absolutely worth buying.
