Yes — the Herz P1 tracks the same core health metrics as the Oura Ring 4: sleep stages, HRV, resting heart rate, blood oxygen (SpO2), activity, stress, and menstrual cycles, all 24/7 from your finger. The key difference is the price: the Oura Ring 4 costs $349 upfront plus a $5.99/month subscription required for full app access. The Herz P1 starts at $59.99 with no monthly subscription — ever. Both are IP68 waterproof. The Herz P1 adds a 90-day money-back guarantee and a 2-year warranty, which the Oura Ring 4 does not offer at the same terms. If you want comprehensive health tracking without the ongoing subscription cost, the Herz P1 is a compelling alternative.

Both rings use optical PPG sensors positioned on the finger — the same measurement location that produces cleaner pulse signals than wrist-based wearables. For the core metrics most users care about — resting heart rate, sleep stage detection, and HRV trends — the Herz P1 performs reliably in everyday use. In our 30-day test, heart rate readings stayed within ±3 bpm of a chest strap reference on 10 of 12 sessions. That said, the Oura Ring 4 has years of proprietary algorithm development and a larger validation dataset behind its scores. For general wellness monitoring, the Herz P1 delivers solid tracking at a fraction of the cost. For clinical-adjacent use or elite athletic performance tracking, the Oura Ring 4's more mature software gives it an edge.

Exceptional Accuracy: The pulse signal from your finger is easily detectable, and with advanced sensors, the Herz P1 Smart Ring provides highly accurate heart rate tracking, making it an excellent choice for precise health monitoring.

Comprehensive Health Monitoring: Track your heart rate, sleep patterns, blood oxygen levels, activity, and stress index, gaining valuable insights into your overall wellness.

Personalization Options: Customize your smart ring with different colors and sizes to match your personal taste and lifestyle.

Compact and Stylish: With its small, lightweight design, the Herz P1 Smart Ring is more discreet and comfortable than larger wearables like smartwatches.

For optimal detection, wear the Herz P1 Smart Ring on the index, middle, or ring finger of either hand. Ensure the ring fits snugly and comfortably at the base of the finger to guarantee accurate readings.

For the best results, position the ring so its sensors sit securely at the base of your finger. The ring can tolerate up to 30 degrees of rotation without affecting data accuracy. To minimize movement, choose a ring size that fits well and doesn't rotate frequently during wear.

Yes, the Herz P1 Smart Ring is IP68 rated, making it waterproof up to 164 feet (50 meters). You can wear it while swimming, showering, washing hands, or sweating without interrupting your health monitoring.

Yes, the Herz P1 Smart Ring can store data offline for up to 7 days if Bluetooth is disconnected. Once Bluetooth is re-enabled, the ring will sync the stored data with your phone. To avoid data loss, we recommend syncing the ring with the app within the 7-day window.

The Herz P1 Smart Ring uses advanced sensors, including optical heart rate monitors and accelerometers, to collect data on your heart rate, sleep, activity, and more. This data is then transmitted to the Herz companion app, where you can view and analyze your health metrics in simple, user-friendly reports.

The Herz P1 Smart Ring features an upgraded battery that lasts up to 6 days on a single charge, giving you more time for health tracking and less time worrying about recharging.

Yes, the Herz P1 Smart Ring works with both Apple iOS and Android devices. Simply install the accompanying app to view your health data, set fitness goals, and track your progress with ease.

The Oura Ring 4 requires a $5.99/month subscription for full access to your health data — that's $71.88 per year, every year, on top of the $349 hardware cost. Over two years, the total cost reaches $493. For users who rely on Oura's advanced Readiness Scores, trend analysis, and deep Apple Health integration, that subscription delivers real value. For users whose primary goals are sleep tracking and heart rate monitoring — the majority of smart ring users — a subscription-free alternative like the Herz P1 covers those needs at a fraction of the total cost.

Several smart rings offer subscription-free health tracking in 2026. The Herz P1 is among the most accessible options, starting at $59.99 with no monthly fees — full access to sleep, HRV, heart rate, SpO2, activity, stress, and menstrual cycle data is included at purchase. Other subscription-free options include the RingConn Gen 2 and the Ultrahuman Ring Air, though both carry higher upfront costs than the Herz P1. The Oura Ring 4, Samsung Galaxy Ring, and Circular Ring all require monthly or annual subscriptions for full feature access.
