By analyzing HRV and Stress along with additional data, SweetBeat HRV provides a deeper dive into health and provides insight into what activities you engage in that effect the health metrics you care about.

IMPORTANT: SweetBeat requires external hardware:
A tested Bluetooth Low Energy Heart Rate Monitor, Wellue DuoEK hand held heart rate monitor or a Wellue VisualBeat heart rate monitor patch. While other manufacturers wrist worn devices work well for heart rate, their wrist worn heart rate monitors are not accurate enough for HRV and so are not supported. The iWatch is not supported.

•Please visit https://www.sweetwaterhrv.com/healthsensors.shtml for a list of compatible Heart Rate Monitors devices.

SweetBeat HRV will also import your Apple Health app data (SDNN, Resting Heart Rate, Average Heart Rate) that is collected by the iWatch or other devices authorized to store metric in the Health app. This data is for viewing purposes only and is not used in any HRV calculation.

SweetBeat has two main components:
•Monitor Stress
•HRV for Training/Recovery

Monitor Stress:
With SweetBeatHRV, you can see your stress levels in real time, giving you the ability to take action to reduce stress. If your chosen stress threshold is reached, SweetBeat’s Relax screen prompts you with a deep breathing screen that includes calming images.

•Stats: The stats screen more widely referred to as the “geek” screen, shows all the metrics being measured. If using the HealthPatch, the user can view the additional provided metrics.
•Graph: The graph screen shows a real-time building graph of your heart rate from RR Intervals. Turning the phone 90 degrees counter-clockwise will bring up the graph in landscape.
•Export RR Intervals: SweetBeat provides RR interval export capability along with other raw data files in .csv format.

HRV For Training:
In competitive sports, improved performance is often affected by alternating periods of intensive training with periods of relative rest. SweetBeatHRV measures HRV, an objective measure of your body’s response to each workout and provides training recommendations based on the morning reading.

SweetBeat Features:
•Customize your Relax screen images with your favorite pictures.
•Track your heart rate recovery after exercising.
•Save and upload sessions to your secure SweetWater Health account at www.BeatHealthy.com.
•Email your RRs and session data for personal analysis off-line
•View your Apple Health data with trend lines

Great live monitoring for HRV and stress

I’ve been using a few HRV apps with polar chest strap for over a month now. I love SweetBeat for seeing live monitoring of several things at once including HR, HRV, stress. However, the recommendations it gives me after analyzing my data are totally different then how I feel or how my 4 other HRV apps analyze the data—all running at the exact same time. It also is the only one that says my parasympathetic system is active when my other apps say it’s severely not active at all (I have dysautonomia and am finding what works for my systems to have more PNS activity when needed than SNS activity, and I track and graph PEM for pacing with myalgic encephalomyelitis.) I would imagine those tracking fitness or managing stress, can also use accurate info about their ANS. I definitely wish I could turn off the “you should do x, y, or z today.” The “gas tank needle” graphic indicating ANS balance has been way off compared to my other apps running at same time. I love that it has a non-annoying HR alarm (a little whistle) but I wish it would continue to sound until the HR was back lower—Would love having option to fully customize HR zones and HR alarm (like keep alerting until HR is back under threshold.) Custom HR color zones would be extra great. I really need it to be iPad screen size. Thank you for taking my suggestions and for making this app.

Thank you for the great input! SweetWater has many clients that have CFS/ME. Please contact support@sweetwaterhrv.com we would like to discuss how you can utilize SweetBeat for tracking ME.

Great hrv app.

Although sometimes buggy software, the support team is very responsive and will help find a workaround. I like the hrv for training, but find the stress calculation to have little to no correlation with my actual stress levels. I'm not sure that the correlation and food features are very reliable or provide any value to me, i find the presentation of information slightly confusing after studying lf power, hf power, ratio and relation to stress, and comparing the measured values with how i feel. I feel that the main thing i can conclude is that we are rapidly developing knowledge in a fairly immature region of health and wellness.

Design needs improvement

This app is great because it makes looking at LF/HF so much easier than other HRV apps.

But the design makes user experience very difficult. For example after you take a reading, to move through all the graphs you have click small radio buttons at the bottom of the screen that are nearly impossible to hit accurately. Could easily make a swipe functionality to move through charts.

Developer Response ,

I am unclear as to what radio buttons you are referring to. The only way to see all your graphs from a session is swiping whether it is at the end of the session or through History>Session. Please contact support@sweetwaterhrv.com and we will be happy to walk you through and figure out what you are seeing. Also, there are small film strip icons on different screens. Tap the icon and a video will run showing you how to use the app and the features and functions. Please contact us.
