Simple, effective, works well with iPhone 4s, March 16, 2013
fast_matt (Dallas, TX USA)
I bought this Zephyr hear rate monitor to get a better understanding of how many calories I was really burning doing different activities - primarily strength training, yoga, Pilates, and cycling.

I've had it for about a month now, paired with an iPhone 4s running the Cyclemeter and Digifit apps, and it's served me well so far.
The sensor has worked seamlessly with Digifit; no issues whatsoever. Cyclemeter has sometimes hiccuped and lost pair when I left the phone on the floor and ran out of range; that required deleting the sensor in Cyclemeter and re-pairing. Since discovering that, I've stuck to Digifit at the gym ($2.99 for the sensor package, or $7.99 for the Pro package).

The sensor band is fairly comfortable, easy to put on, and works well after wetting the pads with water, even when worn overnight.
The sensor is small and lightweight; I mainly notice it when lying flat on my stomach.
Heart rate values have been believable at all times -.


Works with Moto X and Nexus 5 on Kit Kat (Android 4.4) running SenseView Runtastic Pro apps., November 19, 2013
Bike Geek (Boston)
As other reviewers have already stated, the Zephyr HxM Smart is compact, its strap is comfortable, and its heart-rate datastream is dependable. Plus, being a Bluetooth LE/Smart device, the HxM Smart has phenomenal battery life. Personally, I've got way too many devices that need to be charged on a daily or almost-daily basis; I'm glad that the HxM Smart is not one of them.

I'm using my Zephyr HxM Smart with my Nexus 5 and my Moto X, both of which are on Android 4.4 (Kit Kat).

To connect the HxM Smart to your Bluetooth LE equipped Android device, there is a trick that is NOT obvious if you're accustomed to pairing Bluetooth devices within the system-wide Bluetooth settings: DO NOT ATTEMPT A BLUETOOTH PAIRING WITHIN THE SYSTEM BLUETOOTH SETTINGS. Instead, connect to the HxM Smart directly from the app you plan to use.

For example, if you want to use the HxM Smart with SenseView, do the following:

1. First make sure you install the companion.


A nice upgrade from the 1st gen Zephyr (which I've used since 2011), November 9, 2013
W. G. Wilder "Sola_Gratia" (Dallas, GA USA)
  
Works flawlessly with my HTC 1 and fitness app iCardio, is easy to set up and comfortable to wear; I cease noticing it after a few moments. This wonderful technology allows me to track my heart rate during workouts (cycling, weight lifting, cardio), which is recorded by my fitness app and uploaded to my calorie tracker. The "Smart" part of the technology is Blue Tooth Low Energy, a significant improvement over BT 2.0 that ostensibly will power this unit from the replaceable button battery for months. There seems to be a lot of confusion about phone and app compatibility. If this Zephyr HRM does not work for you, it may not be Zephyr's fault; your phone also must support BTLE; only the latest phones (at the time of this writing) support BTLE. So before purchasing this device, check if your phone supports BT 4.0. In addition, not all fitness/health apps support BT 4.0/BTLE. At the moment Endomondo does not; if you do a bit of research you will discover that Endo will add BTLE support.
