Here you will find complete listings of all the classes, objects, methods and functions available across all the parts of the Pebble API. ## Pebble Smartwatch APIs Pebble's smartwatch APIs provide developers with a means of developing applications that run natively on Pebble smartwatches. ### [Pebble C API](/docs/c/) The Pebble C API, used for creating native **watchapps and watchfaces** in C. The Pebble C API can be used in combination with *any* of the PebbleKit APIs listed below to extend the application's functionality. ### [Pebble JavaScript API](/docs/rockyjs/) Pebble's embedded JavaScript API, used for creating native **watchfaces** in JavaScript. The embedded JavaScript API can be used in combination with PebbleKit JS to extend the application's functionality. ## PebbleKit APIs The PebbleKit APIs provides developers with a means to extend their application's functionality by communicating with an application on the mobile device it is paired to. ### [PebbleKit JS](/docs/pebblekit-js/) PebbleKit JS enables developers to extend their Pebble projects by adding a JavaScript component that is managed by the Pebble mobile app. PebbleKit JS is capable of bidirectional communication with with application running on the Pebble smartwatch ### [PebbleKit iOS](/docs/pebblekit-ios/) PebbleKit iOS is an Objective-C library that enables developers to create companion apps for iOS devices that are capable for bi-directional communication with their Pebble API projects. ### [PebbleKit Android](/docs/pebblekit-android/) PebbleKit Android is a Java library that enables developers to create companion apps for Android devices that are capable for bi-directional communication with their Pebble API projects. {% comment %} ## Web APIs ### [Timeline API](/docs/web-timeline/) The Timeline API enables developers to create applications that interact with the user's Timeline, by creating and editing Timeline Pins. ### [AppGlance API](/docs/web-appglance) The AppGlance web API enables developers to create applications that push information to the application's glance in the user's launcher. {% endcomment %}
