Not impressed with Heart Rate and O2

Bill the critic

I'm playing with this for my first time today and my unfortunate impression is that I will return it unsatisfied. This only records heart rate and oxygen saturation every 10 minutes!! That's very disappointing and to me, completely useless. It shouldn't even measure these if it's not more frequent, in my opinion. I set a function to make it record more often but it's poorly documented on how frequent it will measure. To the company,

"please hold your breath for 10 minutes and if you can't, tell me how useful the oxygen saturation test is. "

Exercise and sleeping both cause big changes to heart rate and oxygen saturation. For example, sometimes in a stressful exercise tend to hold our breat. Sleeping with snoring or apnea issues can cause you to stop breathing too. In either case, heart rates increase and oxygen levels decrease but these are very brief and never going to be recorded if the recording interval is 10 minutes. Personally I think you should record these continuously if a user wants them but every 30 seconds is about a minimum to me.

I will continue looking for a device that can properly track my heart rate, oxygen and movements with better granularity.

Update - I may have spoken / reviewed too soon! I tried manual recordings last night and it appears they're may be more frequent recordings when you records at least sleep manually. I can tell how frequent but I can find the clear fluctuations.

Valuable health tool

Zippy Blue Dogz

I have been extremely happy with this device. The information is very helpful for achieving my health goals. HRV is a measure that few devices give, and it’s valuable for understanding the impact of workouts and how well you are recovering so you know if you need more rest or are ready to hit it hard. Or, if you are getting sick!

It’s also valuable, along with resting heart rate to understand the impact of your diet on your body. This has really opened my eyes and as a result, caused me to think twice about what I eat and drink.

Sleep is another valuable data set, and again, you can see how lack of sleep, or great sleep affects your body in multiple ways.

It’s important to understand this is not “instant gratification” data, the value is in the trends, and the trend graphs are very good.

Finally, the app is constantly improving and additional features are being added. There is a vibrant group on Facebook that the developers monitor and respond to. They do the occasional Facebook live so questions can be asked and answered, and they take action on the feedback.

It’s a great team to work with, and a great device!

Great app, great fitness band

Tristan Guerry. Alan Guerry.

A great app has gotten steadily better with each update. Auto-detection of sleep works flawlessly, and all the biometric information is presented so you can easily spot longer term health trends as well as more granular short term data. The auto-detection of various exercises still needs some fine tuning, but I have no doubt it's just a matter of time. A+ for effort.
