The next big trend in bio-hacking is understanding the relationships between different metrics. NatureBeat integrates and correlates data from popular fitness platforms like MapMyFitness, Fitbit and Withings.

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

IMPORTANT: NatureBeat requires external hardware:
A tested Bluetooth Low Energy Heart Rate Monitors. 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. They can be used for Food Sensitivity test.

NatureBeat can be used with IOS 8 and newer. iPhone 5 and newer, iPad 3 and newer, iPad Mini and newer, iPod touch 5.

•Please visit for a list of compatible Heart Rate Monitors, noting that the Wahoo and 60Beat dongles are not supported

NatureBeat has four main components:
•Monitor Stress
•HRV for Training
•Food Sensitivity
•Data Correlation

Monitor Stress:
With NatureBeat, 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, NatureBeat’s Relax screen prompts you with a deep breathing screen that includes calming images.

NEW: Checkup mode is a 3 minute countdown ideally suited for use with the Zoom device. Checkup can be run with any compatible BTLE heart rate monitor chest strap too. The three minute session allows the Zoom user to accurately assess stress and power levels anytime during the day.

•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.

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

Food Sensitivity Test:
If you are sensitive to certain foods, you may not experience symptoms, though your body reacts by elevating your heart rate after eating an offending food. Low level food sensitivities may contribute to inflammation. This inflammation tells the body to hang onto stored fat to combat whatever stress caused the hormonal release. NatureBeat measures your pulse three times after eating and assigns either a “X” (sensitive) or a green checkmark (not sensitive).

The correlation screen uses a patent pending algorithm to correlate all of the data the user has shared with NatureBeat. This data will come from the app itself and any other apps or devices the user has authorized (Fitbit, Withings, and/or MapMyFitness).

The correlation feature turns your data into useful information and provides insight into what combination of activities lead to desired HRV, stress or weight, giving you the knowledge you need to achieve your health and fitness goals.

NatureBeat Features:
•Post your session summary on Twitter to share with friends.
•Customize your Relax screen images with your favorite pictures.
•Track your heart rate recovery after exercising.
•Track the foods you have eaten and your body’s response to them.
•Save and upload sessions to your secure MySweetBeat account at
•Email your RRs and session data for personal analysis off-line

What’s New

Version 2.0

- NatureBeat is now supporting the Wellue DuoEK hand held heart rate monitor and the Wellue VisualBeat patch heart rate monitor. A welcome alternative for the chest strap! All previous heart rate monitor chest straps are still supported. You can find the link in the app under General>Purchase Heart Rate Monitor.
- You can now view your Respiration Rate, SDNN and VLF in realtime, while you are performing a monitoring session. We have also updated your Share data with the new metrics so now you have even more data you can analyze outside of the app.
-Access your Apple Health data. This data is for viewing purposes only and is not used in any NatureBeat HRV calculations.

A Powerful Tool

Whether you're an athlete or fitness/health geek, this is such a powerful tool for the cost!

If you just want a simple app that provides a scaled HRV value to determine whether you should go hard or go easy, this app delivers. If you’re like myself and like to geek out on all the numbers (rMSSD, LF, HF, RR) and even watch a live graph of your heartrate, this is an awesome app.

This app has really helped me to be able to push into the overreached state without falling into the overtraining hole. For example, when I train hard for 2 or 3 consecutive days, my HRV will plummet from a baseline of 69 down to the lower 40’s. It normally takes a few very easy days for my HRV to climb back up, but if work is stressful it will take longer. I just keep the training on the light side until my HRV comes back up to the baseline.

I’m also a user of TrainingPeaks and I consider my HRV value just as important if not more important than my TSB.

The science for correlating high frequency to the parasympathetic nervous system and correlating low frequency to sympathetic nervous system is mixed, but the science behind HRV in general is solid.

I use a Polar Bluetooth heart rate strap with electrode gel/cream and never have had any issues!

Better than all the others…

Of all the HRV tracking apps, software, and hardware I’ve tried, this has everything anyone could ask for, and more. The RMSSD platform insures accuracy, consistency, and the graphs are easy to understand and provide actionable factors that both guide & inform.

Very informative

My neurofeedback doc loves that I’m doing this.
