Welcome to the PebbleOS documentation site!
PebbleOS is a lightweight, power-efficient operating system originally developed for Pebble smartwatches and now released open source. It supports custom watchfaces and apps using C and JavaScript. Optimized for memory-in-pixel (MIP) displays and long battery life, it features Bluetooth sync, a timeline interface, and a strong developer ecosystem through an open SDK.
