Ben Greenfield - NatureBeat

1.The Ben Greenfield software is outdated, causing display misalignment tailored for screens after iPhone 8. 2.Incompatibility issues render essential high-pressure vibration reminders ineffective. 3.Data upload function has ceased due to lack of maintenance on the outdated software, resulting in error notifications. 4.Outdated algorithm yields erroneous HF/LF ratio results for heart rate variability, significantly differing from other software or yielding opposite results. In conclusion, this is an outdated software that is no longer being updated. The new software, called SweetBeat HRV, offers the same functionality and updates. I fell victim to purchasing the old version.

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.

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!
