Congratulations to Our First Heart Rate Monitor Giveaway Winner – Tommy!

Congratulations to Tommy, our first heart rate monitor giveaway winner! We have sent Tommy a free Vernier hand-held heart rate monitor. It’s not too late to sign-up for our next month’s heart rate monitor giveaway. We will be giving away a free monitor every month until the end of the year!

Tommy’s Story:

“I am a software engineer with a pretty sedentary job. I work from home and sit behind my laptop most of the day. Over the years, I have been getting more and more out of shape, so I finally decided to get fit. I dabble in film making and visual effects in my free time so I tend to follow a lot of people from that industry on Twitter. One person I follow started a podcast called Fitness in Post. In one of his episodes, he interviewed a lady named Ronda Collier from your company. She was very interesting to listen to and that lead me to purchasing a heart rate monitor and your SweetBeat HRV and DailyBeat HRV app. Three weeks ago, I started on my journey to get fit and eat healthy. I use your app every morning to check my heart rate when I first get out of bed. I also use another one of your apps, SweetBeat HRV right after my morning workout to check my recovery rate. I get up at least once every hour and walk for five to ten minutes and I average about 14,000 steps a day. So far I’ve lost about 8 pounds, sleep better and generally feel better. I still have about 65 pounds left to loose.”

We are so proud of Tommy for taking his health into his own hands. Our users inspire us everyday to continue making products that help people understand their health. We look forward to meeting more of you during these next month’s giveaways!

Improve your HRV with the Delta Sleeper SR1

Many of you know SweetWater Health’s co-founder and CTO, Jo Beth Dow, as our resident biohacker. She has spoken at many quantified self events about her experiments. Most recently, she has been using the Delta Sleeper SR1 for better quality sleep and longer nights. Below you will find her testimonial:

“I am always searching for new techniques and technology that will help improve HRV.  Our partner and friend, Ben Greenfield of Ben Greenfield Fitness highly recommended the Delta Sleeper and he was posting his morning HRV after using the device.  I was intrigued after viewing Ben’s posts and I had to try it for myself.

I started using the Delta Sleeper SR1, a 1.5 ounce device, to determine what affect PEMF had on my heart rate variability.  Being an ultra lark I never had difficulty falling asleep but sometimes I had difficulty staying asleep.  I would wake up between 3:30 am and 4:30 am and start working.  Fortunately, I was getting 7 to 7 1/2 hours of sleep per night.  I never fully understood until now what affect my rather unique sleep schedule had on my husband.

The Delta Sleeper SR1 was easy to use and while I was sleeping I wasn’t even aware that I was wearing it.  The Delta Sleeper SR1 is a small device that you place on your brachial plexus using a thin adhesive strip. The first night I did not notice any difference.  The second night I was restless but woke up feeling unusually good.  The third night I had decided not to wear the SR1 and I had a very restless night.  I got up in the middle of the night and placed the SR1 on my forehead (this is not recommended application) but I was too groggy to apply the adhesive and place it on my brachial plexus.  I slept in until 7:25 am and felt wonderful!

I have continued to use the SR1 every night.  Even on the nights that I am not sleeping longer, I feel especially clear, relaxed and focused in the morning.  One night I told my husband I wasn’t going to wear the SR1.  I wanted to test the quality of my sleep without the product.  My husband responded, “You’re not?”  I replied, “What, you want me to wear it?”  His response was, “I want you to implant it.”

The SR1 has not only helped me sleep longer but as a secondary effect helped my husband sleep better.  Even the nights that I don’t sleep longer than my previous norm I feel like I am getting more quality sleep and sleeping deeper.  I have two months of HRV data since using the SR1.  My morning HRV has increased  9 points and is moving on an upward trend, reached an all time high HRV on several mornings and my afternoon HRV and LF/HF power levels have increased.  The numbers are impressive especially since the HRV value is logarithmic.

It’s That Time of the Year Again: Apple Releases iOS9!


It’s That Time of the Year, Again!

As we know, Apple rules the world. Every year, they update their operating system and devices. Apple has scheduled the release of iOS 9 for this month. As they update their systems we must update our applications to be compatible. 

While we work on making our code compatible with the new technology, we ask you to remember that you must update your applications as the updates become available.


When you update your device to iOS 9, you must update your HRV application!


  • NOTE: The following applications must be updated: SweetBeatLife, NatureBeat, Stress Detective, Food Detective, PrimalBeat, Wholeistic Coaching & ResilienceZone.
  • If you have one of the following applications you do not need to purchase anything, you just need to update.
  • The updates are available for SweetBeatHRV (previously SweetBeatLife), Naturebeat & PrimalBeat.
  • If you do not update, you will most likely not be able to connect your Bluetooth Low-Energy (BTLE) heart rate monitors. 

In other news, SweetBeatLife will now be called SweetBeatHRV!


How Else Am I Affected?

Apple makes certain things obsolete after updates are released. Due to this, we are not able to update SweetBeat or HRV Sense any longer. These two applications will be removed from the iTunes app store. It is unfortunately, out of our control.


SweetBeat & HRV Sense can no longer be updated and will be removed from the iTunes app store.


We are here to support you through this difficult but necessary change. If you are using SweetBeat or HRV Sense, we have several solutions for you:

  • Update to SweetBeatHRV. The new application has many more features and interactive graphs.
  • If you purchased one of these applications within the last three months, please email us at support@sweetwaterhrv.com and we will take care of you.
  • This will affect those of you using ANT+, as it is not included in SweetBeatHRV. If you are a long time user of ANT+, please let us know. We’d love to hear from you!
  • You can choose not to update your device to iOS9. As a warning, we have noticed that older operating systems do not work as well when a new one is released.
New features coming soon!

New Graphs: SweetBeatLife Update!

Yes, you read it right! There is a SweetBeatLife update available, which includes brand new enhanced graphs. The graphs are completely interactive and allow for a better view of your SweetBeatLife metrics.

Key features of the new graphs:

  • Zoom in by putting your pointer finger and thumb on the graph and moving your fingers away from each other. Double tapping the graph can also be used to zoom in.
  • Zoom out by using the same two fingers and making a pinching motion.
  • By holding your finger down on the graph, you will create cross hairs to pinpoint.
  • There is a yellow circle with an “I” in the middle of it in the top right corner which opens up the graph’s key.
  • Turning your phone to the left will give you a landscape view.

Note: If you do not see these graphs when you open SweetBeatLife, this means you have to manually install the update. You can do this by going to your App store, click on the bottom right tab labeled Updates, and install the SweetBeatLife update.

See below for examples of the new graphs:

We have been constantly working on SweetBeatLife to make it the most full functioning heart rate variability (HRV) application you’ve ever used. We hope you enjoy these new graphs as much as we do!

Happy Quantifying!

Visualizing HR, HRV, and GSR While Watching ‘Interstellar’ by Bob Troia

This blog repost is from one of our more “connected” users, Bob Troia, also known as Quantified Bob.  Bob enjoys tracking and analyzing his metrics based on the effects of many factors such as, his Bulletproof Diet, his glucose reading, even his personality type. To see exactly what Bob is tracking and read into his prior experiments go to his blog.

Interstellar

In this case, Quantified Bob took something as simple as watching the movie, Interstellar, and turned it into a Quantified Self experiment. He used a Polar H7 to capture 3-hours of biometrics, specifically RR-Intervals. The SweetBeatLife app then uses clinical grade algorithms to analyze the data. Anyone with one of our applications and a heart rate monitor chest strap (BTLE) can do the same. Bob exported his heart rate and heart rate variability data from SweetBeatLife, and his Galvanic Skin Response from a Basis B1. Read below to see his heart rate and heart rate variability response.

Heart Rate

“Interestingly, my heart rate trend (on the left, below) looks very similar to the original Reddit user (on the right)! Both of us are using data from our wrist-worn Basis devices – in my case, the older B1 model, and for the Reddit user the newer Basis Peak. Although the Peak is capable of capturing more samples, the data returned from Basis is always an average value for each minute.

Interstellar HR comparison

However, SweetBeatLife is recording data at a resolution of 1 sample per second via the Polar H7. The per-second pulse data is a little bit jumpy and hard to follow (in gray), so I’ll also include a 60-second moving average as well (in blue):

Interstellar Heart Rate Polar H7

It looks very similar to the data recorded by my Basis. Good!

Heart Rate Variability (HRV)

Heart Rate Variability uses a technique in which the spaces between heart beats are measured, and is a good way to measure stress via an individual’s “flight or fight” response (the higher one’s HRV, the better). There are a number of ways HRV can be calculated, and in this case we are using what’s known as rMSSD (root mean square of successive differences). You can check out Wikipedia for a pretty good overview of HRV.

Interstellar Heart Rate Variability

Not only can Bob see when the movie had him in sympathetic versus parasympathetic but he can point out when he was having deep thoughts of gravity and space. Bob was also able to determine that there is, “an inverse relationship between heart rate and HRV, which makes sense – if your heart starts beating faster, you are most likely encountering more stress, which increases your sympathetic response and thus lowers HRV.”

Read more about his Galvanic Skin Response and how Bob interpreted this data, read the original article here. If you want to better understand HRV and the many benefits of tracking it, I recommend browsing around the SweetWater Health Library.
