Jawbone UP 3

The world's most advanced tracker.
The most advanced activity tracker known to man, UP3™ is packed with state-of-the-art sensors that give you the full picture of your health. Heart Health Sensor measures resting heart rate - a leading indicator of your overall health and fitness level. Workouts are automatically recognized and logged. You'll gain an in-depth understanding of your sleep. All this, in an impossibly small, water-resistant design with a full week of battery life. So you'll need to recharge before UP3™ ever does.



”其中自然包括Jawbone所特有的功能，比如心率追踪、皮电反应、呼吸速率、以及皮肤和环境温度。此外，Jawbone UP3还拥有一个三轴加速度计(可对实际运动进行追踪)。
当然，该手环的最大特色，就是能够彻夜工作(续航超1整天)。“
