Developers, start your emulators!

Posted by Pebble Technology (Creator)

It’s been an exciting 2 days, but hold onto your seats...this is just the start! We can’t wait to show you more of the cool stuff that we’ve been working on.

Today, we’re releasing Developer Preview 1 of our Software Development Kit (SDK) for Pebble Time. 

With our SDK, developers can start designing and building new color apps for Pebble Time, or upgrade their current Pebble apps to support Pebble Time. The SDK now includes an entire emulator (on or on your local machine) so you can get started on your apps before you get your Pebble Time. Documentation for timeline APIs is available as well.

Here's a small taste of what's possible with Pebble Time, built in just a few hours by developers who helped us test the Pebble Time SDK (GIFs here):

What's an SDK? It’s a piece of software that developers use to create apps and watchfaces for Pebble. We put a lot of effort into creating the best possible environment for developers. There are over 26,000 registered Pebble developers, who’ve published over 6,500+ apps and watchfaces on the Pebble appstore. On, our web-based IDE, you can get started with Pebble development with examples in Javascript or C (similar to Arduino in complexity). 

Hey, I'm not a developer! What does this mean for me? It means more great watchfaces and apps for your new Pebble Time. Developers are heroes in the Pebble community. They swoop in and create the beautiful watchfaces and apps out of nowhere, delighting everyone in their path. For example:

Already, we’re seeing some fantastic ideas for apps and faces for Pebble Time.

Feel free to Tweet, FB, Instagram or Reddit the watchfaces and apps you create. We'll choose some of the best to feature in an update. Can't wait to see what the world makes!

      Does this watch have the smartstrap? Thanks Calum

      Grr PEBBLE!!! only thing worse than no updates is dropping a bombshell update that means people may loose spots on early birds etc and then not stick around to answer any questions!

      I really hope this version allows the simple function of turning off the pebble in a single push of a button rather than through series of menu trees. Perhaps just pressing the middle button for an extended period of time, say 2 seconds?

      Hi there,

      I am happy owner of Pebble a and can't wait for the new pebble. I am a amobile app developer. I am extremely enthu about developing apps for new pebble. I am from India, I love to develop apps in local language in India. Will the new pebble support Indic font rendering ( I know you guys are working on Chinese), so I am guess you are already working on complex font rendering . So indic kind of work by default. But I am just curious.

      Thank you.

      @SCOTT FURDA There isn't a speaker built into the watch.
      @Tim Douglas Check out the NavMe app currently available for Pebble. It has a companion app in the Play store.

      That should have read, "...I have android AND Microsoft phones..." - meaning I'd like to be free to use the best watch (Pebble) with both, or all, my devices

      Let's make Pebble Time the first truly multi platform smartwatch, and create for Windows Phone using the universal apps and APIs pod Windows10, ready for the platform to grow.

      Keeping the Pebble system linked to all systems Android, Apple, Microsoft, Tizen, BB, FireOS ... Will allows wearers to link to any their phone if they wish - I have Android asked Microsoft for work asked home, for example.

      ... Not been a developer but willing to take a look

      I think you should include a "Dick Tracy" fedora with each watch

      It would be great to get turn-by-turn notifications from Google Maps - one buzz for left; two for right; long buzz for stop and look at your map - you could even use it riding a bike!

      Looks good so far, I know the new watch will have a microphone for quick voice replies but didn't see any mention of a speaker to hear call audio. So in the kickstarter video at 2:35 his mom calls and he denies the call but sends a voice would this be just an audio response to the person who called and if so how would that audio file be delivered especially cross platform IE Android to Apple?

    11. Tim Hedstrom on

      I hope someone makes an app for onstar especially to control the Chevy Volt and Spark EV.

      This got me excited, I can start developing an app before I've got my watch...
      But, apparently, I can't get to the part of the app on my phone (iOS) to enable the Developer Connection before pairing with the watch that I don't have yet :(
      It is really this way or did I miss something?

      Guys... guys seriously... seriously, guys... stop being awesome. Offline emulator? Seriously, I'm going to develop the hell out of it! mwahahahaha!

      Pebble doesn't have a speaker. It alerts via vibrations, and they are easily noticeable.

      Everything looks great what about ring tones, how loud will the sound from the watch be, enough to hear in a crowd?

    16. Elmer on

      It's things like this that let me know my money went to good use. My first time backing Pebble. And already I can see I made the right choice. Keep the updates coming guys and keep up the hard work, truly appreciated.

    17. Ahmad Nasrallah on

      Awesome ideas! looking forward seeing new apps :)

    18. Yonatha Maulana on

      cool ideas next generation of pebble

      Yes, YES!!!

    20. Rene Pot on

      Awesome guys! Looking forward to seeing awesome apps taking this thing to its limits!

    21. Jeremie Lariviere

      very cool!

      Getting 'Try running `pebble convert-project` to update the project' on the cloudpebble site. But don't see how I can run that.

      Shouldn't you have 2 microphones and QNX sound tech for optimal ASR? Also, aren't Maluuba the best NLP engineers? Not really sure what you're doing but reminders on wrist are great for elderly.

      Any chance of a Kickstarter exclusive color? Not some ugly lime green either. Some classy that people would actually want, but could only get by backing.

    26. Ben on

      @Anthony you choose your color at the end of the campaign when they send out backer reward surveys

      Love it!! Have no developer experience, but may use the SDK to make a stab at building an app that can link through my phone to my Zephyr Bluetooth Heart Rate Monitor..

      What do you want us to do with the color apps & faces when we've created them? Can't publish on App Store as nobody can install them yet. Are you going to have a separate Timeline App Store ready for when you release the Pebble Times?
      Also would be good to upgrade the emulator to be able to capture "screenshots", so we can prepare for publishing.

    31. Fabián Núñez on

      I seriously need that Ministry of Silly Walks face.

    32. w9jds on

      YES! Thanks for releasing the SDK Early!!!
