Chris Welch:

Your physical interactions with the Up3 (and Up2) are based around a bewildering system of taps. Tap twice to wake it up, and then hold to toggle between modes. That’d be simple enough if it worked reliably every time, but I regularly found myself tapping repeatedly to trigger the lights hidden beneath the Up3’s aluminum housing. Too often, it just didn’t register. Next time, they should really put a button on it.

Niestety nie tylko przycisk jest problemem…

And that brings us to the heart. Initially, I was pretty excited as Jawbone executives spoke about the Up3’s heart rate monitor. Whereas Apple, Microsoft, and most other fitness bands use LEDs and sophisticated algorithms to sample your blood flow and produce a best guess at your heart rate, Jawbone went with the sensors mentioned earlier. It’s a lot like putting your finger on a treadmill’s heart rate sensor; the Up3 „measures the resistance of skin tissue to tiny electric currents,” according to Jawbone. But is that more accurate than the path Fitbit, Microsoft, and Apple are pursuing? Well, it’s impossible to know. Right now, Up3 only measures your resting heart rate. And it only does that once a day. One time.

Ta firma kiedyś mnie urzekła swoim UP i potem UP24. Ich software był jednym z najlepszych na rynku. Niestety, od tamtej pory wiele się zmieniło. Bugi, niezrozumiały kierunek rozwoju… Up3, który mierzy tętno raz dziennie. Droga w dół jest szybka, ale ciekawe czy się jeszcze podniosą.
