HRV Tracker for Watch vs BreathTuner HRV Usage & Stats

Heart Rate Variability measurements recorded by your Apple Watch can give you insight on the stress level your body is under. By using HRV Tracker to track short-term measurements and long-term trends, you can see how your workload during the day, workout sessions or sleeping etc affect your body's readiness, recovery and stress level. Simply put, the higher your HRV is, the better. ***Requires an HRV capable Apple Watch with watchOS 6 or later*** HRV Tracker for Watch integrates with the Health app and uses data stored in the Health app. To make sure your Apple Watch is capable of recording HRV measurements, please open the Health app on your iPhone to see if any HRV measurements exists. Go to > Health app > Browse > Heart > Hear Rate Variability. ***Get Notified*** HRV Tracker makes spotting changes in your HRV easy by monitoring your HRV measurements in the background and showing notifications after your HRV drops under or rises above your desired levels. HRV Tracker will monitor changes in individual measurements and also your 24 hour HRV average. You can change the default notification levels directly in your Apple Watch app. Please note that notifications can get postponed for example because of a low battery level. ***Apple Watch for daily tracking*** Browse through last seven days of HRV measurements by using the digital crown. See how measurements compare to your seven day period and individual days. By tapping the graph you can toggle through the first values of each day. Use complications on your Apple Watch to stay informed on changes in your HRV. Besides the automatically recorded HRV measurements you can use the Breathe app on your Apple Watch to record new HRV measurements. Start a Breathe session in the Breathe app and after the session ends a new HRV measurement will be available in HRV Tracker. ***Compare HRV to other key metrics*** Find possible causes for changes in HRV by using the comparison graphs available on your Apple Watch: -Sleep hours: By default HRV Tracker will use sleep data provided by sleep apps that add sleep data to HealthKit. If no sleep data is available HRV Tracker will calculate estimated sleep hours per night (estimated sleep time will only be available in the Apple Watch app) -Activity: By default HRV Tracker will use your Active Energy (calories) as the activity metric. In the HRV Tracker Apple Watch app you can choose to use a custom activity score that emphasizes the intensity of daily activity. -Daily resting heart rate (RHR). Toggle between comparison graphs by tapping the upper part of the screen. ***Follow Long-term HRV trend*** Follow your long-term HRV trend on your iPhone and compare your short term measurements to all-time data. -Select week from weekly graph to see daily HRV values of the selected week. -Browse through all daily HRV values of the selected day -Compare daily HRV averages to other relevant daily metrics: Activity, Sleep (if available in the Health app) and Resting Heart Rate ***Widgets on iPhone*** -Medium sized widget with chart showing all daily hrv values -Multiple small widgets to choose from ***Privacy*** Data read from the Apple HealthKit database is only used to show information related to your Heart Rate Variability. Information read by HRV Tracker is only stored and used locally on your iPhone and Apple Watch. ***How is it measured*** Heart rate variability measurements used by HRV Tracker are calculated by measuring the variation between individual heartbeats. Your Apple Watch automatically measures your HRV in the background and stores the outcome into HealthKit. HealthKit uses SDNN heart rate variability, which is calculated using the standard deviation of the inter-beat (RR) intervals between normal heartbeats (measured in milliseconds). Besides background measurements generated automatically by your Apple Watch you can use the Breathe app on your Apple Watch to generate new measurements.

BreathTuner HRV

Already breathed today? Probably! We are always breathing, but mostly unconsciously. What a pity! Because we can achieve so many positive things for ourselves through breathing: When you breathe at your optimal breathing rate, your heartbeat synchronizes with your breathing and beneficial, balancing and healing processes are set in motion that bring both your psyche and your body into optimal balance. BreathTuner is the first and only app that allows you to find your personal and optimal breathing frequency. It is also called resonance frequency and is determined by analyzing breathing and heart rate variability (HRV) simultaneously. Take the basic test and you'll know how to set your Apple Watch for Breathe (Meditation) to get the most benefit for you! Or do you use one of the many Breath-Pacers or do daily exercises to improve heart rate variability? Even then, you should use BreathTuner to find out at what breathing rate your HRV is optimal. No other app can currently give you this fully automated functionality. Did we mention that the basic functionality costs next to nothing? BreathTuner uses scientifically proven algorithms, is based on the latest research and uses high quality and proven HRV technology from our HeartBreath app. BreathTuner guides you through a series of simple exercises while being paced by the soothing breath sounds of the VaYou Biofeedback app. The BreathTuner measurement is at once a relaxing and even meditative exercise that enjoyably centers your mind on the flow of your breath. In doing so, the app measures your abdominal breathing and heart activity, and it does it all using only your iPhone! For this, we went to the technical limits. You don't need an extra sensor, but you can use a chest strap like the Polar H10 as an alternative for pulse detection. This captures a real ECG and we analyze it for the HRV calculation. But BreathTuner works just as well with the finger pulse measured via the iPhone camera. And if you want to become a BreathTuner Pro-User, even more detailed analysis is available via an In-App Purchase. You can then determine your individual breathing resonance frequency with very high accuracy! BreathTuner was developed with the utmost care by the makers of the apps HeartBreath HRV and VaYou Breath Biofeedback. You get a quality product at the cutting edge of scientific research with the most beneficial breathing sounds available in the world today. BreathTuner integrates with the Apple Health app (Mindful Minutes). To breathe costs nothing, also air is fortunately still free and BreathTuner is at your disposal - almost free!
