Opening the Black Box: Publishing Pebble’s activity-tracking algorithms

This is a guest post by Nathaniel Stockham, a Ph.D. student in Neuroscience at Stanford University.

When I started my study of bipolar disorder, I spent an inordinate amount of time comparing different devices, each differing in ease of use, reliability, battery life, remote access, and cost. What eventually led me to Pebble was my need to know exactly what was being calculated.

After reviewing dozens of commercial and clinical devices, I determined the most important variables to measure and designed two algorithms to capture the most salient motion characteristics. After months of validation in collaboration with Pebble and the Stanford Wearables Lab, I am making these two algorithms available to the public to encourage the use of a standard set of measures.

Celebrating Women in Computing at Grace Hopper 2015

Below is a guest post by Erin Boehlert, a Computer Science student at UNC Chapel Hill. Pebble invited Erin to attend the 2015 Grace Hopper Celebration of Women in Computing in Houston, TX and blog about her experience during the conference.

First of all, thank you to Pebble for sponsoring me and a few other women at UNC Chapel Hill to attend The Grace Hopper Celebration of Women in Computing (#GHC15)! I wouldn’t have been able to go without it. This was my first time attending Grace Hopper, so I wanted to make the most of my experience. Here are some of the highlights from the event:

Pebble: More to Love at Sweet New Prices

Celebrating Pebble’s Growth with New Things to Love

When we launched Pebble two and a half years ago, our mission was simple: build the most enjoyable, customizable, and versatile smartwatch on the market at an accessible price. The market has exploded since then, but our mission remains the same.

Last January at CES 2014, we unveiled Pebble Steel to critical acclaim. It was a resounding success and the catalyst for tremendous growth. Since then, we’ve opened the Pebble appstore, which boasts over 4,000 apps that have been downloaded five million times. Our open platform counts over 18,000 developers, from passionate hackers to partners like Mercedes-Benz, Pandora, the Weather Channel, and ESPN.

ESPN for Pebble Has Landed: Bring Sports Scores to Your Smartwatch

ESPN for Pebble

Heaven for any sports fan is a comfy couch, a big screen with the game on, unlimited hot wings, and all the free time in the world. Sadly, real life—work, errands, dance recitals, the DMV—loves to burst that happy bubble. There’s no shortage of stuff vying for our attention, pulling us away from enjoying the wide world of sports.

Even with DVRs and live-streaming, it’s impossible for sports junkies to keep tabs on all the teams, games, and league matchups we care about. There’s this insane stretch from November to February where you’ll catch me juggling between countless college football, NFL, NBA, and college basketball games every week. During this ugly (and awesome) time of year, there’s no peeling me off the couch: productivity nosedives, relationships suffer, and my belly grows.

Thanks to the ESPN Pebble smartwatch app, these dark days are over.

Pebble Makes Fitness Shine, Partners with Misfit

When we created Pebble, we designed it with health and fitness in mind—making it waterproof and including an accelerometer. Since then, we’ve partnered with RunKeeper, Strava, Puma, and many more to give Pebble users a compelling health and fitness experience. We now have sleep trackers, step counters, and even swim watchapps that take advantage of Pebble’s open platform.

But we’re not standing still. Today we’re delighted to announce that Pebble and Misfit have joined forces to bring state-of-the-art activity tracking to Pebble smartwatches on wrists worldwide. Misfit, makers of Shine—a beautiful fitness and sleep monitor—have applied their expertise with user experience and algorithms to the Pebble ecosystem.

The Misfit watchapp is available today in the Pebble appstore, and lets users count steps and track their activity right from their wrists—no smartphone or Shine required. In addition, Misfit’s latest iOS app will be available from Apple’s App Store soon. It includes support for Pebble watches and tracks additional metrics such as calories burned and distance traveled.

Today’s app is just the first step towards seamless integration with Misfit and Activity tracking on Pebble. We’ll unveil additional functionality in future updates, so stay tuned! As the first milestone in an ongoing partnership and collaboration between Pebble and Misfit, we aim to provide intuitive health and fitness tracking for all.

Hacking with Pebble

Spark + Pebble = Building the Internet of Things at Maker Faire Bay Area (Updated)

UPDATE: If you’re in the Bay Area and want to demo a cool Pebble hardware hack you’ve built, tell us about your project! Your Maker Faire ticket will be paid by Team Pebble if we select your hack.

Pebble was born from hacking. Back in 2008, Eric plugged a Nokia phone display and Bluetooth radio into an Arduino board and our first prototype came to life. Hacking is part of Pebble’s DNA, and is reflected today in the awesome apps made by Pebble developers using our SDK — from flying an AR Drone to controlling a Tesla. That’s why you’ll find Pebble at Maker Faire Bay Area on May 17 and 18 at the San Mateo Event Center.

Pebble and Spark

Come hack with Pebble + Spark at Maker Faire Bay Area, 17–18 May!

But we’re not doing it alone. We’re sharing a booth with the wonderful folks at Spark, makers of the Spark Core — a tiny, Arduino-compatible WiFi development board. The Spark team created an easy-to-use product that allows anyone to connect everyday electronics to the internet over WiFi. We have a lot in common, from our Kickstarter beginnings and passion for hacking to our open platforms and strong developer communities.

Pebble at GDC: let’s play

When we launched SDK 1.0 almost a year ago, we knew it was only a matter of time until developers started making games for Pebble. Before long, we saw great Tetris, Pong, and Asteroid clones available for download from My Pebble Faces.

Now, with SDK 2.0, which includes accelerometer support, and the Pebble appstore for iOS and Android, there’s never been a better time to develop games for Pebble. In addition to classics titles like Pebtris, Pebloid and multiplayer Chess, Tiny Bird (a Flappy Bird clone) is consistently one of the most popular downloads on the Pebble appstore. Below are the top 10 games currently available on the Pebble appstore.

  • Tiny Bird
  • MiniDungeon
  • Pebtris
  • Ledge Climber
  • Chess
  • Falldown
  • Orbtime
  • Pebloid
  • Blackjack
  • Ask the Helix Fossil

We believe Pebble is a great new platform for studios around the world to create awesome  games — specifically mini games and casual games. Today at GDC, we’re introducing three new titles which are going live on the Pebble appstore: Mr. Runner (Zing Games), an endless runner; Icon Pop Quiz (Alegrium), a fun quiz game; and Hatchi (Portable Pixels), a Tamagachi like game.
