According to the assurances of the Californian manufacturer, its wearable gadget is one of the most progressive models among fitness trackers. But is it really so?..
Sensors
At first glance, it really seems that the Jawbone UP3 has conquered Olympus: it has body temperature sensors, environmental sensors and a bioimpedance heart rate sensor in its arsenal. Of all this variety, only a heart rate monitor works, which initially measured the heart rate readings exclusively at the moment of awakening. With the advent of updates, he began to record data more often, but somehow this process cannot be controlled — the gadget decides when it is necessary to take measurements.
Design
The bracelet is not equipped with any screen, and the role of indicators is performed by three coloured LEDs. This allows you to hold out on a single charge of a 38 mAh battery for about a week. The gadget is firmly held on the hand, but some owners blame the fact that the sensors can cut into the skin.
Appendix
The branded application deserves the greatest praise. In addition to measuring activity and the number of steps taken, it allows you to enter food data, add other users to the comparison, build all kinds of graphs and give useful tips. Also, the application is very motivating, sending notifications during the day about the percentage of completion of daily goals.
Dream
Out of the box, the gadget was not able to determine the moments of the beginning and end of sleep — these parameters had to be set manually by tapping on the body, which does not always respond to touch. The updates that arrived saved the device from this shortcoming and the bracelet learned to track sleep quite clearly, making mistakes only within 10-15 minutes. The "smart alarm clock" on board the tracker effectively recognizes the phases of light sleep and wakes up its owner at a predetermined time interval.
Potential
Jawbone engineers didn't finish their product a bit. In terms of “hardware”, it really is ahead of competing models, but it’s still impossible to use all its functions. The only good news is that each new update brings fresh “buns” to the bracelet.
