Have you got a current driving licence? <a href=" https://www.sosfaim.be/stendra-fda-approved.pdf ">stendra feedback</a> Withings has designed it to pair over Bluetooth with a smart phone, and using a related app you can track everything from exercise targets to sleep patterns (yes, you wear it to bed so that an accelerometer can monitor your nocturnal, er, behavior). When used in conjunction with the app, the Pulse offers a lot of features and you don't have to be an Iron Man competitor to get the most out of it. It's inconspicuous, which I like (no one wants to look like a Borg or be quizzed every time someone notices you're wearing an odd gadget), and the rechargeable battery lasts for a couple of weeks. Its best feature is the pulse rate monitor, which other devices like the Fitbit Flex and more expensive Nike FuelBand lack.
