my new companion day and night

Such a device can be a good motivational tool when you move too little and wants to monitor functions such as heart rate and sleep. However, most devices and apps fail after a short time: too vague, too heavy, too complicated to use.
The Withings Pulse has however convinced me quickly.
1. Advantage: It is very small and light, I have him for ever in your pocket, where he did not fall
2. Advantage: The tape for recording at night I like very much. It is very light and flexible, you'll notice it hardly on the wrist. Important for me, because otherwise I can not sleep with that thing.
3. Advantage: The connection to the iOS app via BT is simple, quickly and easily.
These are the decisive points for me.

For measurement accuracy:
1. Pedometer
Is only an approximate value and has a certain inaccuracy. One would have to determine otherwise for the route etc. personal values ​​as step length, etc. And who makes always the same steps.
But is it true about halt. Series of tests: 5 steps made 5 counted. Made 10 steps, 11 counted. Made 200 steps, 202 counted. Ok .... if you do 12,000 steps a day, so he is one of possibly 120 too much. But that is not to, but if you have just made 5,000 steps, or 15,000
2. Pulse
Fair I against my sphygmomanometer
Tolerance is +/- 2. I can live with, because the blood pressure meter measures never exactly
3. Sleep function
So for me to vote the awakenings with the experienced consistent and even when you sleep lightly or deeply, seems to measure the device. The course I can not verify, I am not a sleep laboratory .... but from the feeling it's true

With the associated app to get along well and now Mass daily values ​​and trying to break my records .... certainly not motivated for years to come, but surely a few months. I love that thing fun and that's what matters.
