HRV Tracker for Watch is a lifestyle application developed by Sydvesti Oy that allows you to monitor your Heart Rate Variability (HRV) using an HRV capable Apple Watch with watchOS 6 or later. By tracking short-term measurements and long-term trends, you can gain insights into your body's readiness, recovery, and stress level. The application integrates with the Health app and uses data stored in the Health app. You can compare HRV to other key metrics such as sleep hours, activity, and daily resting heart rate.

The application makes it easy to spot changes in your HRV by monitoring your HRV measurements in the background and showing notifications after your HRV drops under or rises above your desired levels. You can browse through last seven days of HRV measurements by using the digital crown on your Apple Watch, and see how measurements compare to your seven-day period and individual days. Besides the automatically recorded HRV measurements, you can use the Breathe app on your Apple Watch to record new HRV measurements. Follow your long-term HRV trend on your iPhone and compare your short term measurements to all-time data. HRV Tracker for Watch is a useful tool for anyone looking to monitor their body's stress level and improve their overall health.
