Jawbone released Up, an app-enabled wearable fitness tracker, roughly one year ago, but a slew of hardware issues ensued, and now the company has corrected those errors and launched a second iteration of the product today with 141 new parts.

The primary problems with the original version of Up concerned water contamination and flexibility. It was apparently not durable enough to handle moisture, and many users who came into contact with water subsequently reported damaged internal parts, while other users snapped components if they bent or twisted the bracelet. There were also many complaints regarding battery life issues.

Jawbone’s CEO and founder Hosain Rahman said his team went back to the drawing board, however, and the new Up design is now perfect after 46 weeks worth of user trials and testing:

“UP marks our commitment to solving everyday problems for real people. We’ve combined hardware, software and data, developed 28 new manufacturing processes, and created unparalleled testing standards validated by nearly three million hours of real-world testing. The resulting breakthroughs have allowed us to create the category’s first truly day-and-night wearable product – a band that looks great and fits effortlessly into the way you live, along with an app that delivers detailed data with meaningful insights to help you achieve your goals.”

Up is essentially a rubberized bracelet with sensors and a 3.5 mm headphone jack concealed by a removable cap. Users must plug Up into an iPhone to sync it with an iOS app and retreive measured data on their sleep habits, activity level, moods, and more.

The bracelet comes in three sizes and eight colors, and it is available starting today for $129.99 at Jawbone.com, Apple, AT&T, and Best Buy. The updated Up by Jawbone iOS app is also available for free in Apple’s App Store.

A Wristband and App System, Powered by MotionX®, is a New and Innovative Tool for Better Daily Living

SAN FRANCISCO – Nov. 13, 2012 – Jawbone® today announced UP, a new wristband and app system that helps you discover things about yourself that you never knew. UP tracks how you sleep, move, and eat, and gives you personalized insights to help you make smarter choices to feel your best.

“UP marks our commitment to solving everyday problems for real people,” said Hosain Rahman, Jawbone CEO and Founder. “We’ve combined hardware, software and data, developed 28 new manufacturing processes, and created unparalleled testing standards validated by nearly three million hours of real-world testing. The resulting breakthroughs have allowed us to create the category’s first truly day-and-night wearable product – a band that looks great and fits effortlessly into the way you live, along with an app that delivers detailed data with meaningful insights to help you achieve your goals.”

UP Gives You a Rich Picture of Yourself

UP utilizes sensors in the wristband, the powerful phone in your pocket, and data in the cloud to deliver a narrative of your daily life:

  • Sleep: UP employs a revolutionary sleep tracking system. Sophisticated motion-sensing technology tracks micro-movements of your wrist to deliver unprecedented detail including how long it took you to fall asleep, how much light vs. deep sleep you got, how long you were in bed and how many times you woke up during the night. By using the new Power Nap feature or setting the silent Smart Alarm, UP wakes you at the most optimal point in your sleep cycle so you wake up feeling refreshed and alert.
  • Move: UP gives you comprehensive information about how you move throughout the day, including active vs. idle time, intensity of movement, total steps, distance, and calories burned. UP also vibrates gently to remind you to get up and move when you’ve been inactive for a specified amount of time.
  • Eat: UP helps you understand more about your food choices. Simply take a photo of your food to create a visual journal, or go deeper by scanning a barcode or searching the database for more complete nutritional information.
  • Mood: UP lets you keep track of how you feel throughout the day so you can correlate how your sleep, movement and eating affect your mood.
  • Insights: UP analyzes your data to deliver highly personalized insights. It reveals connections between different elements of your life, shows how you compare to others, and educates with new information that’s tailored for you. The more you use UP, the more powerful the insights will become.

UP is Designed for the Way You Live

UP is a sophisticated computer wrapped comfortably around your wrist and built to withstand everyday life. Encased in a smooth, hypoallergenic, medical-grade rubber, UP is shower- and splash-resistant so that you can wear it all day and night. With up to ten days of battery life you rarely have to take it off to charge.

“The UP band is powered by the patented MotionX® engine which encapsulates years of technology development and innovation on the biomechanics of natural human motion. The accuracy and power efficiency of MotionX has been critical in enabling UP to deliver a 24/7 product experience,” said Philippe Kahn, CEO and founder of Fullpower, developer of the MotionX technology.
