FREQUENTLY ASKED QUESTIONS

WHAT IS UP? WHAT DOES IT DO?

Band + App + You = The Up System

UP is a system that takes a holistic approach to a healthy lifestyle. The UP and UP24 wristbands track your movement and sleep in the background. The app displays your data, lets you add things like meals and mood, and delivers insights that keep you moving forward.

HOW DO UP AND UP24 TRACK MY MOVEMENT AND SLEEP?

UP and UP24 use a precision motion sensor and powerful algorithms to passively track and quantify your steps, distance, calories, active time, and idle time. The UP app then calculates calories burned based on your age, gender, height and weight, along with activity intensity and duration. UP and UP24 use actigraphy to track your sleep, monitoring your micro movements to determine whether you are awake or asleep.

WILL IT WORK IF I CYCLE, DO YOGA, OR OTHER NON-STEP-BASED WORKOUTS?

The UP app allows you to log the duration and effort level of a variety of different workout types, so you get credit and estimated caloric burn for non-step-based activities. Additionally, the UP band has a Stopwatch mode that lets you "tag" the start and end of your activity. Once you've synced your band, you can enter the details of your workout.

HOW DOES UP TRACK WHAT I EAT, AND WHERE DO THE NUTRITION GUIDELINES COME FROM?

We've made tracking what you eat or drink quick and easy, with the flexibility to go as light or deep as you want. This can be as simple as using a photo, or as detailed as capturing all the information in a nutrition label.

HOW DOES UP SYNC?

The new UP24 band was designed to wirelessly sync your data in the background using Bluetooth Smart. The original UP was designed to quickly and simply sync your data with your device using the 3.5 mm headphone jack. Carefully plug your band directly into the jack, and do not bend UP during sync.

IS IT WATER RESISTANT? CAN I WEAR IT SWIMMING?

Your band is rain, splash, sweat, and shower-resistant, but you should remove your band before swimming, surfing, or exposing to other extreme conditions and activities like saunas and steam rooms. Do not submerge your band in liquids, including hot tubs or baths, at any time.

WHAT IS THE BAND MADE OF?

UP and UP24 is encased in medical-grade, hypoallergenic rubber. It is smooth, flexible and completely latex-free. The cap is made of Nickel and TR-90 Nylon. Inside, the bands contains sophisticated technology — a processing core, battery, vibration motor, sensors and memory — so treat your band with care and avoid unnecessary bending.

HOW SHOULD I TAKE OFF/PUT ON MY BAND?

Bend your band just enough to take it off and put it on, one end at a time. Avoid excessive stretching and twisting, and take extra care when syncing or removing clothing.

HOW DO I CLEAN MY BAND?

Clean the exterior of your band with Isopropyl Alcohol or alcohol-based sanitizer applied to a cloth or cotton swab. Do not submerge the band in any liquids.

HOW LONG DOES THE BATTERY LAST?

The battery in your UP24 band lasts up to 7 days and UP bands lasts up to 10 days when fully charged.

WHICH WRIST SHOULD I WEAR IT ON?

We've found wearing UP24 and UP on your non-dominant hand delivers the most accurate results, but either wrist will work.

WHAT IS A SMART ALARM AND HOW DOES IT WORK?

The Smart Alarm is a great way to wake up feeling refreshed. Set up to four alarms, and UP24 and UP analyzes your sleep cycle to wake you with a gentle vibration, at the most ideal time within a 10, 20 or 30-minute window or an exact time you specify

WHAT IS AN IDLE ALERT AND HOW DOES IT WORK?

The Idle Alert is a great way to remind you to get up and move. You can set an Idle Alert within the app, so the band will gently vibrate if you've been inactive for a period of time.

WHAT DATA IS STORED ON THE BAND, IN THE APP, OR ON MY PHONE? WHAT IF I WANT TO DELETE MY DATA?

Your band will store up to nine months of movement and sleep data. You can delete any activity or sleep tracked in the band via the Help screen in the app. Performing a hard reset of the band will also erase all data from your band. Once synced, your data is stored in the Cloud so you can access your data anywhere, though the app will cache your most recent data to improve performance.

IS UP CONNECTED TO FACEBOOK OR TWITTER? CAN I SHARE MY UP DATA THROUGH MY EXISTING SOCIAL NETWORKS?

Currently, the UP app allows you to share your move, sleep, eat summaries through Facebook and Twitter. Also, UP allows you to create a team of your friends and family so you can share your progress and cheer each other on. You can connect with friends who use UP through your address book, Facebook and Twitter contacts, or by email lookup, and then choose what information is shared with them within the UP app. Only your name and profile image are publicly searchable in the UP directory.
