Starting Sunday, Jawbone will offer a wristband that will gently wake you up with a vibration. The Bluetooth headset maker says the bendable, waterproof gadget will sync with Jawbone’s iPhone app called Up (there's a version in the works for Android). It will track your sleep and exercise. Sensing micro-movements at bedtime, it can tell when you’ve fallen asleep and whether you are in a light or deep sleep. That way, it can wake you in your lightest moments of sleep. Up will also track your daily moments to keep up with all the exercise you are getting - from workouts to little movements. You can also track your eating habits with the device. It will run $99 at Best Buy, Apple, and AT&Tstores.
