Know what's happening with you, instantly: Your sleep, your activity, what you're eating. A way to quickly check in with your progress and see what your friends are up to. Sleep The sleep mode in UP tracks small movements while you're asleep. You can see hours slept, time to fall asleep, light vs. deep sleep and waking moments. UP even lets you set a Smart Alarm that wakes you up silently at the time that leaves you feeling most refreshed. Activity The precision motion detection system in UP tracks every move, capturing a complete record of your day's activity. A Stopwatch Mode lets you mark specific active periods so you can see how everything from going for a run to walking the dog contributes to reaching your goals. Food and Drink Take a photo of your food, scan a barcode, browse the image gallery in UP or search the ingredient database to record what you eat and drink.
