Used with LG G3, an R LG G Watch for viewing, and Endomondo software that allows both to prepare and record their activities onto the phone and website, and also receive information about the watch during activities (practice not to remove the current phone). Reliable appliance, easy maintenance, you can change the elastic band which disengages from the transmitter, and the battery does not show weakness (it is announced in one year, I guess it depends on the intensity of use ). I associated this transmitter to a Loop or app Polar Beat, but integration is frankly not practice, data is not put together to make a whole. That's why I like Endomondo. I also use it indoors, heart rate is displayed directly on the SCI-FIT machinery (Trendmill, bike, elliptical) simultaneously on the LG watch. For this type of sensor, Polar has a good reputation which I find justified. It was on the connected devices (polar watches, loop, apps) that I find both expensive and not very flexible hence my choice for an alternative. The LG G Watch R has the added advantage of aesthetics and integration with Android, that does not offer a Polar watch the same price.
