A total flop!

"A just 8 grams heavier Smart Tracker, which allows you to analyze your activity around the clock, measure your heart rate and improve your health." - This is the slogan for the product Withings and vying for health-conscious customers. After about 1 month, more or less bad experience I am angry at myself, to be taken in by the full-bodied advertising promises.

"It measures steps, calories burned, altitude profile and distances traveled."

Although steps are somehow counted, but the altitude profile does not work at. In a mountain covered on foot height distance of around 800, Pulse showed just 200m. Around 10,000 steps should it have been. And about 12km distance traveled?!? No, I'm not risen to the Mount Everest, but was just on a mountain hike in the Alps. A day later: Rauf by mountain railway (no measurement, that's ok), descent on foot of around 1200m above sea level to about 600m above sea level. If a height distance of at least 600m arise - Pulse showed only 147m to ... And the stride are downhill certainly less than on straight track. Thus not only the distance traveled, but also the calorie consumption displayed is incorrect. This reveals the greatest concept of fault Pulse: He has installed a GPS and do not therefore to the terrain texture (up, down, etc.)!

To Sleep Tracker: Here nothing happens but a subsequent evaluation of the movements. During sleep every few minutes is automatically measured and stored, press the button after 8h shows the device "100% sleeping target" to. Whether one "little" or "a lot" or has "good" or "bad" slept, says that is not enough. By means of an algorithm, after you synchronize the wax / deep sleep / light sleep phases in the APP indicated - by beams and numbers. An interpretation of the sleep is not included.

The only feature of the "Pulse" which is reasonably good works the pulse measurement. The measurement is made by means of opto sensor: Finger waiting for the back of the pulses and a few seconds. Operation during an activity or even a long-term measurement is not possible (a lawyer would "analyze activity around the clock" the promotional statement probably regard as misleading). The pulse can be measured even cheaper ... and who is called a heart rate monitor with chest strap his own, which may even do during exercise. The latter is even more accurate and cost a fraction of the "Pulse".

Measurement errors are one thing, but a height sensor is not functioning properly, and an app that often hooked in the operation, sometimes displaying data and sometimes not make the "Pulse" Viewed Total unusable. And I doubt that both APP and firmware are significantly better with time. No purchase recommendation!
