Pebble App and Developer Transition Updates
Into the Future
In the months since our last community update, we’ve been setting the table for the Pebble ecosystem’s next major transition. We’re working hard to make sure Pebble users can keep enjoying their smartwatch experience for as long as possible. We’re happy to share the progress made so far with Pebblers today as a part of our continuing efforts to honor Pebble's legacy, ecosystem, and functionality.
Pebble.js - Pebble Package Edition!
We're pleased to announce that Pebble.js has now been published as a Pebble Package. Pebble.js lets developers easily create Pebble applications using JavaScript by executing the JavaScript code within the mobile application on a user's phone, rather than on the watch.
Announcing Pebble SDK 4.3
Things have been a bit 'quiet' recently, but we're back with another fresh Pebble SDK! In this release we've included one of the most frequently requested APIs, exposed the raw HRM sensor value, released PebbleKit 4.0, plus added an exciting new BLE HRM mode.
4.2-beta4 SDK - Emery Edition!
We're incredibly excited to announce the first public beta of the Pebble SDK 4.2. This is the first time that developers can experience the new 'Emery' platform which is specifically created for the upcoming Pebble Time 2.
Ready for Pebble 2
The latest 4.1 releases of the firmware, mobile apps and SDK bring support for the new Pebble 2 smartwatches, which have started appearing on the wrists of developers and reviewers around the globe.
Timeline - The Future of the Past!
If you’ve been living under a rock, or have just been sunning yourself on the beach for the past week, you might have missed the launch of Pebble OS 4.0. This new version introduced some fantastic new features, such as the updated health app, timeline quick view, app glances, Rocky.js and a new system launcher.
Announcing Pebble SDK 4.0
Today we have the pleasure of announcing the release of Pebble SDK 4.0. We have published an updated version of the Pebble Tool, the SDK itself, and we've deployed 4.0 onto CloudPebble. It's time to get busy!
Prime Time is Approaching for OS 4.0
Pebble developers of the world unite! Pebble OS 4.0 is just around the corner and it's now time to put those finishing touches on your projects, and prepare them for publishing!
Introducing Rocky.js Watchfaces!
We're incredibly excited and proud to announce the first public beta version of Rocky.js watchfaces for Pebble. Rocky.js is ECMAScript 5.1 JavaScript running natively on Pebble smartwatches, thanks to our collaboration with JerryScript. This is an incredible feat of engineering!
Creating Native Companion Apps with JS and Cordova
Creating companion apps using PebbleKit Android and PebbleKit iOS is a great way to extend the functionality of your Pebble watchfaces and apps, but what if Java or Objective C just isn't your thing? What if you love JavaScript? What if you just don't want to write the same companion app twice?
Now you don't have to! Enter Cordova - an open source framework for building cross-platform mobile apps using web technologies such as HTML5 and JavaScript. What does this mean for you? One framework, and one codebase for building Pebble companion apps for iOS and Android!
Introducing Clay - App configuration made easy
It is with great pleasure that I present to you, Clay, a Pebble package that makes it easy to add offline configuration pages to your Pebble apps. All you need to get started is a couple lines of JavaScript and a JSON file; no servers, HTML or CSS required.
A Wild SDK Appears
Developers rejoice - we’ve released the first version of our SDK 4 developer preview! This SDK enables you to start building applications for the new Diorite platform (Pebble 2), and includes a set of new APIs for interacting with the 4.0 user experience.
In this blog post we’ll dive into the App Glance,
UnobstructedArea
, and
AppExitReason
APIs, and explain
how you can use them to create great experiences for your users!
Introducing Pebble Packages
I am thrilled to announce that, as part of SDK 3.13 and Pebble Tool 4.3, we have launched our own packaging system: Pebble Packages!
Time to Expand Our Core Business!!
You might have noticed a bit of a buzz around Pebble today - we have officially launched our third Kickstarter campaign, and it is jam packed with exciting new products and features for developers to explore and hack on. We have been hard at work not only creating the next generation of health-focused smartwatches, but also refining what great wearable user and developer experiences look like. We are introducing an entirely new class of wearable device, and adding a modern JavaScript SDK that takes advantage of the Web APIs JavaScript developers around the world know and love.
There is a lot to take in, so we’re here to help break down what’s new and exciting for our favorite developer community!
Pebble.js Support for Chalk!
After many morning coding sessions on the weekends, Pebble.js has been updated to support the Chalk platform (Pebble Time Round). This update is available in CloudPebble, and ready for you to work with right in your browser with no setup!
Supporting Chalk required a ton of bug crushing to become compatible with the new 3.0 style status bar, changes to accommodate reduced memory on the 3.x Aplite platform, adding new features such as text flow and paging, and making it easier to target multiple platforms by adding a feature detection API.
Don't Panic - We're Here to Guide You
New developers typically begin their journey by following our tutorials, and then moving on to projects of their own. The guides section of our documentation is intended to help developers go beyond the basics - to help understand some of the more complex APIs and concepts required to develop a Pebble app. Ultimately, we want developers to feel comfortable enough with our platform that the reference documentation can be their primary source of information.
We’ve known for a while that our guides section was a bit of a weak link (sorry for the inconvenience!) - and to that end, we’ve spent a lot of time thinking about, and writing, a new set of guides that should help to better guide you along your path to becoming an awesome Pebble developer!
Take the Pebble Health API in your Stride
I've been desperate to write a blog post about the Pebble HealthService API since it's initial release last month, and now I can finally share its awesomeness with you. I'm also going to show you how you can use this exciting new API to build an ultra-cool clone of the Stride watchface by Pebble.
Introducing App Debugging
Happy leap day! Today is a once-every-four-years day of bizarre date-related bugs, and thus an opportune moment for us to introduce our latest developer feature: app debugging in the emulator! This gives you a powerful new way to hunt down errors in your apps.
JavaScript Libraries for C Developers (pt. 1)
One of the exciting changes introduced in SDK 3.9 was support for including Multiple JavaScript Files to your projects. While this feature doesn’t allow you to run any JavaScript you previously couldn’t, it makes organizing your PebbleKit JS code a heck of a lot easier.
In this blog post, we'll look at how to refactor some exisiting JavaScript 'library code' into an actual module for PebbleKit JS, making it simpler to use and share!
Hands-on with the RePhone smartstrap kit for Pebble Time
For those that don’t already know, the RePhone smartstrap kit was part of a highly successful Kickstarter campaign by Seeed Studio to create the world’s first open source and modular smartphone. Part of their campaign was to create a smartstrap kit for Pebble Time that integrates with RePhone modules such as GPS, NFC, and external batteries. This is the first commercial smartstrap project I’ve managed to lay my hands on, and it’s awesome!
Multiple JavaScript Files
In SDK 3.9 we will introduce a new feature to the Pebble SDK: the ability to cleanly use multiple JavaScript files in the PebbleKit JS app portion of your project.
Bringing the Family Back Together - 3.x on Aplite is Almost Here!
The time has almost come for Pebble Classic and Pebble Steel to get firmware 3.x!
This is great news for users who get access to all the improvements and fixes since 2.x, as well as new features such as timeline, Quiet Time, no more eight app limit, Standby Mode, and last but not least one new color (gray)!
But let us not forget about Basalt and Chalk app developers, who also have a lot to get excited about - a huge new user base of Aplite watch wearers!
This blog post aims to help developers using SDK 2.x features and APIs to migrate their apps to a single 3.x codebase. As well as bringing compatibility to all older watches when they upgrade to firmware 3.x, these changes will also serve to remove a lot of complex and ugly conditional code that has needed to exist in the meantime. Let's fix some apps!
Unifying bitmap resources
With the upcoming release of firmware 3.8 on Pebble and Pebble Steel, and the associated SDK 3.8, we have decided to redesign how image resources work in Pebble apps.
Introducing Pebble Tool 4.0
I am pleased to today announce that version 4.0-rc4 of the pebble
tool is now
available. The key new feature is a new paradigm for dealing with firmware and
SDK versions. This makes it much easier to deal with differing SDK versions, or
to test code on multiple (emulated) firmware versions.
A note: while the tool is now at version 4.0, the SDK, firmware and mobile apps will not be following. Pebble tool versioning is now completely independent of the rest of the Pebble ecosystem.
Nuance Brings Pebble The Freedom Of Speech
In October, we gave developers access to the microphone in the Pebble Time via our new Dictation API, and almost instantly we began seeing awesome projects utilising speech input. Voice recognition is an exciting new method of interaction for Pebble and it has created an opportunity for developers to enhance their existing applications, or create highly engaging new applications designed around the spoken word.
Speech-to-text has been integrated with Pebble by using the Recognizer cloud service from Nuance, a leading provider of voice and language solutions.
Migrating to Pebblekit iOS 3.0
Starting with Pebble Time Round, we are moving towards communicating with Bluetooth Low-Energy only. This means there are some updates to PebbleKit iOS to support this. Here are the major changes and steps to take to support the new BLE connection.
What's New
- Companion apps have dedicated, persistent communication channels
- Start mobile apps from Pebble
- 8K AppMessage buffers
- Swift support
Pebble Time Round SDK - Developer Preview 2
You may have heard about Pebble Time Round, our newest addition to the Pebble family which adds a whole bunch of new possibilities, challenges, and opportunities for our dedicated developers to get creative with.
With a new platform usually comes a new SDK to play with. Well, why wait? All developers can now get their hands on the new SDK 3.6-dp2 or use it on CloudPebble. This is a preview of the first Pebble Time Round-compatible SDK, allowing developers to realize their ideas for new and improved watchapps and watchfaces. Have a favorite classic round watchface that looks cumbersome on a rectangular display? Try it out on this one!
The Road to Pebble SDK 3.0 in Ten Questions
We launched the first version of our new SDK with support for Pebble Time two days into our Kickstarter campaign. Since then, we have updated it every week, releasing six iterations of our developer preview. Some of these versions included major new features like support for color in the emulator and support for the timeline. Some other features were more subtle, like the new antialiased drawing mode and the updates to the animation system. All these changes together, and a bunch more that you have not seen yet, will form the SDK that you will use to build watchfaces, watchapps and timeline apps for all models of Pebble watches in the coming months.
These updates include lots of changes, and no matter how hard we try to document everything there are a lot of unanswered questions. Some subjects have just not been addressed by the developer previews yet, some need more explaining and as always there are things we just missed in our communication efforts.
In this update, I want to answer publicly the most frequent questions received from the community in the last few weeks. I will cover components that have been released but also those that are still to come so you have the information needed to plan ahead and prepare your apps for the Pebble Time launch.
Get Ready For Smartstraps - Warm Up Your 3D Printer!
Many of you have read about smartstraps on our Kickstarter page and contacted us for more details. Today we are releasing mechanical and electrical designs so you can start working on the next generation of straps: Straps that expand the functionality of Pebble Time and Pebble Time Steel.
The smartstrap connector is situated on the back of your new favorite watch. Smartstraps can extend below the watch to reach that connector while Pebble Time is worn. In the 3D files we are releasing today, you will find a generic connector that can work with most straps. Of course, you can also design completely new straps if your project calls for one!
Time to Add Color to These Pebbles
You might have noticed on the Internet that we announced the brand new Pebble Time on Tuesday. Almost 50,000 members of our community have already backed the project on Kickstarter this week.
Most important for all of you is that today we are announcing the first developer preview of Pebble SDK 3.0. This new SDK is available right now to all Pebble developers, via CloudPebble or to install on your computer. Both versions include an emulator with support for the new hardware, and of course the color screen!
Pebble Smartwatch Emulator in CloudPebble!
We're thrilled to announce the latest addition to CloudPebble: a Pebble smartwatch emulator!
A New Year of Hackathons!
It's a brand new year, which for developers and hackers can mean only one thing - a new year of hackathons! Throughout January and beyond, Pebble will be making appearances at various events (large and small) so if you spot an event near you, be sure to come along. We will be giving away Pebble swag and selling refurbished Pebbles for $50, and will also be on hand to answer any questions you have as well as help you create the best hacks on Pebble. We saw some awesome apps and hacks arise from hackathons in 2014, but we think the best is yet to come!
See below for details on the most immediate dates, or the Pebble Developers website Events page for all our plans for future events. If you are organizing a hacking event that we could attend, be sure to get in touch.
Happy New Year!
Hey Pebble Devs!
It's been a great year for us at Pebble as well as all the awesome community developers that come up with ever more surprising and useful apps for Pebble. We would not be where we are today with over 5000 apps without all the hard work that you guys put into your apps, so thank you!
We look forward to another amazing year with you in 2015, May your hands always be busy!

XDA - Pebble Developer Challenge Winners!
Almost two months ago the XDA Forums and Pebble set out on a mission to find three amazing apps/watchfaces and their developers. We called it the XDA - Pebble Developer Challenge and last Friday it all came to a close! These three developers have taken the Pebble and truly stretched its limits to create some amazing products and we want to show them to you!
The XDA - Pebble Developer Challenge was a 3-week competition - your opportunity to pitch your proposal for the best Pebble app and bring it to life with a Pebble of your own. Of the 20 proposals that we selected for the second phase, the developers of the best three Pebble apps have been invited to attend the 2014 Pebble Developer Retreat in October. We also gave each of them a Pebble Steel to flaunt!
There were a lot of really great entries to the second phase of the competition and all of them deserve a quick download! Check out the complete list of apps and watchfaces that were made during the competition on the XDA forums.
Getting Ready for Automatic App Updates
We are pleased to announce that we will soon be automatically updating apps installed from the Pebble appstore. We believe this will be a significant improvement to your ability to get your work into the hands of your users, as well as to the user experience.
However, as developers, you need to make sure that your app is ready for these updates. In particular, you will need to make sure that your app conforms to our new version numbering, and that it can tolerate persistent storage left over from old app versions.
CloudPebble Graphical UI Editor
Today we're adding a new feature to CloudPebble that will make it easier than ever to build your watchfaces and watchapps! The new UI Editor will let you graphically build the user interface for your C app; you can then use the generated C to build anything you like.
XDA Forums - Pebble Developer Challenge
Can you #MakeAwesomeHappen? Your app idea could win a Pebble and a trip to our 2nd Annual Pebble Developer Retreat in Mountain View, CA!
The XDA - Pebble Developer Challenge is a 3-week competition - your opportunity to pitch your proposal for the best Pebble app and bring it to life with a Pebble of your own. We'll be awarding Pebbles to the 20 best app proposals to give even first time developers a chance to work on our platform. Of the 20 proposals that we select the best 3 Pebble apps created will be invited to attend the 2014 Pebble Developer Retreat in October and we'll give them each a Pebble Steel.
