Withings Pedometer 

Bottom Line Up Front:  This is a good and effective pedometer.  It just plain works and has a lot of great features which are listed below.  It is unfortunate that it never made it.

Pedometers come in all shapes, colors, and sizes.   This particular model is the perfect shape and size to fit on your belt and the buttons are in the right place so you do not hit them by accident.  The strength of the Withings Pulse O2 is that it is a belt mounted, watch mounted, shirt mounted, and arm-mounted pedometer all in one.  The ways it can be worn are only left to the imagination.  

Package Includes:  

• 1 black or blue pedometer
• 1 silicon cover
• 1 watch band
• 1 charging cable.  
• Quick Start Instructions.  You download the tracking software for iOS or Android.  

I used this pedometer for 4 weeks.  It survived my testing and multiple drops.  It is an electronic pedometer.  It is available on eBay used.  

Testing:

One thing that I really like about this pedometer is the silicon waist clip that it slips into.  It is fairly sensitive to movements and does register as well as the Fitbit.  I am going to compare this to my iPhone, Apple Watch, and Fitbit to give you an idea of how accurate the steps are.  If you look at the four charts of data, you will see the Withings is very accurate and within the 500 step range.  The calories seem low and I am not sure why.  

Calories are clearly different as I said before.  The sleep measurements were within 15-30 minutes of the Fitbit’s sleep study so I would say it is fairly accurate.  The pulse oximeter and pulse are very accurate.  I tested both against a medical-grade model of each.  I would recommend this if you want a pedometer.  I am not sure if the pulse oximeter is accurate if you have a medical need but it should work for maximizing your running efficiency.  

Recommendations on the Withings:

1. Good pedometer.  It does not have all the bells and whistles of the Fitbit or the Apple Watch but then again they do not measure pulse oximetry.   
2. Good sleep measurements.  I found that it was within 30 minutes of the Fitbit.  
3. It has pulse oximetry!  If you need pulse oximetry for anything but a respiratory and cardiac problem, this watch is for you.

The bottom line: This device is no longer available. I would still recommend the Steel HR watch if you want to avoid the apple watch.
