Plastic Samples, iPhone 5 and More!

iOS 6 Update and iPhone 5

Bit of news: Apple released an update to iOS this week. iOS 6 is available for free on all the phones that Pebble supports (iPhone 3GS and up). We’ve had access to iOS 6 through the iOS Developers program for the last few months, and we’ve been testing our software with both iOS 5 and 6. The big news in iOS 6 is a new Bluetooth profile calledMAP. We’ve integrated a MAP receiver into Pebble, but we still have a bit more testing to do with the iPhone 5. So far it’s working really well! There is no reason Pebble should not work perfectly with iPhone 5.

Samples from our Plastics Factory

I mentioned in Update 17 that we were about to start the injection molding process. Creating molds or ‘tools’ is hard, literally. The process involves carving a Pebble-shaped cavity out of hard steel blocks and even with our accelerated schedule, it took 6 weeks. We had to make separate tools for each of the pieces of the watch (buttons, case, lens, strap).

After weeks of work, we ran the first test shots of the mold. It’s awesome to see the long, hard work of our industrial designer, tool designers and mechanical team pay off.

This is an important step towards mass production. Steve, our industrial designer, is in Taiwan right now evaluating samples which are literally hot off the presses. We think they look great for first shots, though we’ve got a bunch of tweaks to make to ensure that all plastic components work and look perfect. The only color we’ve made so far is black because we can’t afford the down-time needed to fully clean the tool. As soon as we have samples in other colors, we will post pictures.

We will leave color selection open past Sept 30 at (Entries can be submitted past Sept 30 now). We will email all backers before closing color selection.

Tons of buttons!

Steve, our industrial designer, was on-site in Kaohsiung, Taiwan and took a bunch more photos (full album).

Printed Circuit Board (PCB) Progress

In parallel to the plastics work, we’ve made several revisions of the circuit board. With each revision we eliminate more bugs and improve the design. In response to a problem we had with the antenna, we created 3 different potential designs and then prototyped and tested each sample extensively inside an anechoic chamber. The best design prevailed and we’ve integrated that solution into our PCB.


We’ve got the whole team working extremely hard on Pebble, but there is a lot of work left to do.

Software Development

On the software and firmware side, we’re in the process of strenuously testing Pebble’s ability to receive new updates wirelessly via a smartphone. This means that even after you receive your Pebble, you can update the software on your watch simply by tapping a button on your phone. Our software team is also busy writing the underlying code for Pebble’s customizable user interface, as well as the apps, like watchfaces, notifications and more, that run on top of the Pebble operating system.


Now that our plastic manufacturing process is up and running, we’re able to make lots of test units and iron out the kinks in the software, as well as the hardware manufacturing process. We’ve designed a strenuous test plan that will put Pebble through its paces. Right now (before we go into mass production) each aspect of the design, from water resistance to button presses to battery lifecycle, is being tested. Then when the factory is in full production mode, every single watch will be tested to be in compliance with our quality requirements.


(This section has been reposted on our forums for discussion)

The last update we’ve published about Pebble’s Software Development Kit (SDK) was in June, when we described what the Pebble Android SDK would look like and Since then we’ve been pretty quiet on the subject.

I’d like to take this opportunity to talk about our roadmap towards creating an awesome developer environment on Pebble. At the moment, we’re focusing 95% of our software effort on writing the base operating system and features for Pebble, on top of test routines that run in our factory. The sheer amount of work is enough to keep our 5 person software team quite busy. We feel it’s important to build a strong foundation that’s highly usable for both users as well as developers.

Part of that foundation is the ability for Pebble to easily run third-party apps. We’ve built this into the core architecture of our OS. The following is our plan to enable developers to create software that works with Pebble. Please keep in mind that this is a roadmap, we’ll be releasing more info over time.

  • Android SDK: It’s easy to integrate new or existing Android apps with Pebble. Our SDK uses intent messaging, allowing other apps to push messages, notifications or even sports data to Pebble. As soon as Pebble ships, developers will be able to use the API calls described on to integrate their apps with Pebble
  • Notification API: Web developers will be able to add Pebble integration to their webapps as well. We’re building an OAuth 2.0-enabled endpoint linked to thePebble Account system. After asking Pebble users to authenticate, Notification API-enabled webapps will be able to push notifications, alerts and other data directly to a Pebble. The API takes care of all the communication between the web, phone and Pebble.
  • Watchface SDK: All the tools needed to create your own custom watchface for Pebble. This is our first experiment with 3rd party code running directly on Pebble’s microcontroller. Developer tools and documentation are the most difficult part of this SDK stage.
  • iOS SDK: Things are a bit more complex on iOS. There is no simple method for doing interprocess communication between apps. We’re pursuing a few different options. We’re confident that the solutions we’re building will work.
  • Expanded Native SDK: At this stage we’ll expand the featureset of the native development platform introduced with the Watchface SDK. Think games, sleep trackers, remote controls and other more complex apps.

Thanks for bearing with me through this long update. If you have any questions, please do not hesitate to email Thanks again for backing Pebble!

Tidbits from around the Pebble world

  • Shipping test has been working out well. We sent 120 test shipments to a few backers around the world to test our logistics provider and optimize the process to ensure that packages arrive safely, quickly and with as few fees as possible to our backers.
  • Backers, you’ve been asking about the backlight! We’ll post a video on our social media accounts (twitter/Facebook/Vimeo) showing it off fairly soon
  • Andrew is in Taiwan right now working on our production test plan (among other things). Here are the latest pics
  • Here’s a short video of a pug-based screen saver/graphics test on a pre-production Pebble. This is NOT the real strap, just a random sample I had on-hand.

As usual, we’ll continue posting small updates in between our Kickstarter Updates and responding to questions on the Pebble Forum.

Thanks again for backing us, Pebblers!

User Interface Preview + Updates


Bit of business before we get to the cool demo. I’d like to apologize for the abrupt way that I mentioned we would not be able to begin shipping Pebbles in September (inUpdate 17). It’s clear now that this information should have been highlighted and discussed more thoroughly.

Planning and scheduling a major manufacturing project is complex. We’re working hard to complete the interconnected tasks that make up the production process. For me and the hardware engineers on the project, a large percentage of our time is spent exchanging complex spreadsheets filled with components specs by email, Skyping about the dimensions of minute hardware requirements and IMing our manufacturing team and factory. Not super exciting. That’s why we’ve decided to share the more interesting stuff (photos, video and more!) in updates.

Our goal is to provide you with accurate information and interesting examples of our progress via these updates. We’re working quickly, but we don’t want to compromise on quality. While we won’t be posting a shipping date until we’re extremely certain that we’ll be able to meet it, our feeling is that by monitoring our progress by the updates you’ll have an excellent feel for how the project is going. When we do share the ship date, it won’t be too surprising because you’ll have seen the project come together in these updates.

Ask-Me-Anything about Pebble today at 11am Pacific!

I can only go into so much detail during these updates. That’s why I’ll be hosting a thread on Reddit ( today at 11am Pacific (2pm EST, midnight Mumbai) where you can ask me any other questions you might have about Pebble.

User Interface (UI) Preview

Martijn is Pebble’s User Interface designer and iOS developer. Check out the video in high resolution (full screen for best effect) for a preview of the Pebble UI. Keep in mind this is just a preview and subject to change as we continue to develop the software. For example, the font size is customizable, eg you can select to have emails shown on screen in arger print. The next step is to implement this UI for the watch itself and test it thoroughly on a prototype Pebble.

Martijn used iOS to create a prototype Pebble for quick designing. Here is an example of an incoming email on Pebble.

Other random tidbits from the Pebble world

  • Starting a shipping test. Volunteer Pebblers around the world will receive an empty shipment from us to determine how long the shipping process will take. ThanksTwitter followers!
  • Started working on the Manufacturing Test Plan (MTP)
  • Ran into an antenna issue. Working through it with a bunch of antenna experts. We’ll figure it out.
  • Started tooling on a bunch of simple components like the USB charge cable and shipping box
  • Tested tons of different watch strap samples to make sure we get the texture just right
  • Ordered 500,000 more resistors. You can never have too many resistors!
  • We’re working on a Pebble Account page where backers can update their shipping information.
  • In the next update, we’ll post more info about the software development progress.

That’s it for now. Thanks again for backing us, Pebblers!

Orange Wins! + Manufacturing Prototype Photos

Voter’s Choice

Without further ado, I’d like to present the Voter’s Choice color….Orange! It won with almost 2000 out of more than 10,000 qualified votes.

I think it looks pretty snazzy! The exact color appearance may vary from this rendering as we work with our plastics supplier. And if you don’t like orange, don’t worry! As a color backer, you’re entitled to pick any of the (now) 4 color options for each one of your Pebbles: Black, White, Red or Orange. We will send out a survey to request your selection later on in the project.

Manufacturing Update

The Pebble team has been bouncing back and forth between Palo Alto and Taipei a lot over the last 6 weeks. The factory that we selected has an R&D facility in Taipei while their main manufacturing and assembly locations are in China. Andrew, Steve and I have all travelled separately to Taipei to oversee the transition between the design and manufacturing stages of the project. In terms of our schedule, we’re sticking pretty closely to an aggressive timetable we put together at the end of May (remember our first timetable was created before we launched on Kickstarter, when we were expecting to manufacture just 1,000 Pebbles). While we won’t be able to start shipping Pebbles in September, our current schedule has us on track to go from manufacturing zero to 15,000 Pebbles per week as soon as possible.

Eric checking the power consumption of Pebble’s backlight module

We’re currently in a phase called Engineering Verification. During this phase, the factory produced samples of the entire product. We’re currently evaluating each individual component (case, lens, circuit board, charge cable, etc) and we’ll tweak the design as necessary. The design needs to be nearly perfect before we move into a phase called ‘tooling’ during which the factory creates hardened steel tools for injection moldingPebble’s plastic components.

Prototype Lens

Remember our tiny printed circuit board (PCB) design from Update #15? Here it is in real life attached to our custom PCB test fixture.

Another key component in our design is a flexible printed circuit (FPC). See that empty space in the middle? That’s where the battery fits in.

Oodles of Color

Hi everybody!

Quick update before the Canada Day long-weekend.

Color Selection

We’ve started accepting color suggestions. So if you’ve got any ideas for cool Pebble colors, here’s how you can get your voice heard! The best way to send us your color is with the hex color value. Don’t forget to create a memorable name, then send your suggestion to us via

After you post your suggestion, we’ll create a render of Pebble using your suggestion and post it on our Pinterest page. If you like someone else’s color combination, be sure to repin, tweet, like or generally talk about it!

Next week, we’ll be sending out an email to all backers of a color pebble with a link to the color voting survey, taking into consideration all the suggestions that we’ve received.

PCB Layout Complete

A major milestone is complete…we’ve created the final design for our printed circuit board (PCB). This is the main electronics board that contains all the integrated circuits and passive components that make up Pebble. It’s double sided…so that 3D render above is just one side! The wires coming out the bottom are from the vibrating motor.

This is close to the actual size of the board. It’s roughly the size of the ‘tab’ key on a MacBook keyboard.

Android Developer APIs

Pebble was at Google IO this week. We used the opportunity to start the conversation with developers around our Android APIs. If you’re interested, you can learn more This is just the beginning of our developer outreach, we’ll be releasing other sections of our SDK over the coming months.

Summer Plans

Hi Pebblers,

Just wanted to share our game plan for the summer. We’re putting together a lot of moving pieces:


Steve from Pebble, Herman and David (from Dragon) in the middle of a plastic molding discussion

  • Factory bring-up: working with our factory to finalize the design of each individual component and subsystem of the watch, moving towards the first factory-made prototype of Pebble
  • Component sourcing: orders have been placed for all electronic components on the board multiplied by 85,000!
  • Software: a whole bunch of new software engineers joined our team very recently. They’re working on things like the user interface and interaction design (read: what the buttons will do and more!), Pebble’s Software Development Kit (SDK) and APIs for developers, and our iOS and Android apps.


Instead of keeping you wondering when we’ll post our next update, we’d like to make a commitment to post an update (at least) once every three weeks.

So that means three weeks from now, we’ll have posted our next update. We’re looking forward to sharing all kinds of cool things with you during the next few months including updates from the factory, links to developer information, screenshots of the iOS and Android app as they take shape, preview videos of Pebble in action showing off the interface, announcement of new app partners and more! One thing I want to say up front: we are not planning on announcing any new dates or timeframes relating to manufacturing. This is our first major production run and we don’t want to start making promises like ‘next week we’ll have the first samples!’. We’ll update you as much as possible, but we won’t be mentioning dates.

We’re also posting updates on Twitter @pebble and Facebook. These updates are official (from the Pebble team) but the final word about Pebble is always in an update. So if there is any confusion, the updates on Kickstarter will always be correct.

Color Selection

For all the backers of a color Pebbles…this is what you’ve been looking forward to! In an update (as well as email) we’ll be publishing a webpage where all color Backers will be able to vote on a color from a short-list of colors that we’ve seen people talk about on our comments, forums, Twitter, Facebook, other websites and more. Your vote will not tie your Pebble to that specific color…if you don’t end up liking the Voter’s Choice color, you’re free to choose one of the other 3 colors (Arctic White, Jet Black or Cherry Red).


Pebble is hiring! We’re looking to meet an experienced Developer Evangelist and hopefully convince him or her to join our team. If you are programmer who has written APIs, consumed a lot of APIs and/or really really enjoys talking with other developers about APIs…we’d like to meet you! Please email us at with your experience in this area, links to github/twitter/blog etc.

Pebble Campaign Success!

Thirty-seven days are up…and we have reached the end of our campaign. We set out with a goal of raising $100,000 and thanks to you, we’ve raised over $10,000,000! We are extremely happy that you’ve given us the opportunity to make Pebble a reality. Our current goal is clear: over the next few months we’ll be working 24-7 to make Pebble as awesome as possible, and get it onto your wrist as quickly as possible.

Over the next few weeks, expect to see a variety to updates related to the voter’s choice colour survey, team introductions, and manufacturing updates. We will also be in correspondence with you via email for specifics like colour choices and shipping information.

Thank You Backers (or Pebblers, whichever you prefer)! All 68,928 of you. For those that didn’t get to participate in our campaign, you can sign up for future releases

You can also get even more involved through our forumsfacebook, or twitter pages.

International Pledge Note

Hi Pebblers!

We’re almost there! Just a little bit of housekeeping from Pebble HQ. Our Kickstarter campaign will be closing on Friday May 18 at 8:00PM Pacific Standard Time.

At that time, your credit cards will be charged – a process that may take a few days. This is a reminder to make sure that the credit card you have used has enough credit to fulfill your pledge and is still active (has not been cancelled). We want to make sure that everyone who signed up for a Pebble receives one.


To change your credit card information:

1. Click on the “Manage Your Pledge” button. You must be signed into Kickstarter to see this button.
2. Scroll to the bottom of the page.
3. Click on the “Change Payment Method” option. Please be very careful not to press the “cancel pledge” option beside it! If you cancel your pledge, you will lose your reward and we cannot restore it!
From there you will be sent to an Amazon page where you can check on or correct your credit card information.


We will also be receiving contact emails for each of our Backers through Kickstarter. In the months after the project closes, we’ll be emailing you directly with colour selection, shipping address requests and other updates.

As a bit of an aside – Eric, Steve and Andrew have sent us a couple of pictures from China. Looks like they’ve been talking shop and eating dumplings! You can follow the adventure on Pinterest or @pebblewatch.


This rest of this update is specifically for backers with shipping addresses outside of the United States

There has been some confusion over the international shipping fees. Since your credit cards will be charged when the campaign closes on Friday, an update seems the best way to make sure everyone has pledged properly.

Canadian or International backers: Please make sure you’ve added/included shipping fees in your pledge total.

If you have not done this, here’s how to manage your pledge and add shipping:
1. On the Pebble Kickstarter page, click on the button that says “Manage Your Pledge.” You must be signed into Kickstarter to see this button.

2. Type your pledge amount in the first box. Make sure that your pledge amount is the appropriate reward amount plus the applicable shipping fees.

Check the following table to verify your pledge level including shipping.

Please NoteIf you pledge any less than your reward level, you will lose your reward position and someone else might pick it up. For example, if you pledged $115 for a jet black Pebble and forgot to include international shipping, pledge $130 and NOT just $15. You will receive a new pledge confirmation email from Amazon, and Amazon will only bill you once.

3. Click continue and confirm your pledge in the pop-up window.

4. From here you will be required to sign into your Amazon account. For this step, continue exactly as you did when making your original pledge.


If you have questions, please check out our forum post: or check the comments on Kickstarter. If you really really need to, you can send me an email at But please check the comments to see if your question has been answered already.

Kind regards, Sarah + Pebble Team



Hi Pebblers,

Quick checkin from our boarding gate. Andrew (lead engineer), Steve (industrial designer) and I (Eric) are about to head off on a trip to China. We’re flying to Hong Kong, then crossing over into the Dongguan area. We’ll be checking in with the factories that are helping us bring Pebble to life.

Pebble is sold out!

After we posted on Tuesday, it took about 26 hours for the remaining Pebbles to sell out. You guys move fast! For those who didn’t get one, you can still sign up here to find out when more Pebbles will be available.
