Pebble is a smartwatch developed by Pebble Technology Corporation based in Palo Alto, California that shipped from 2013 to 2016. Created by Eric Migicovsky, funding was conducted through a Kickstarter campaign in 2012. It was the most funded project in Kickstarter history at the time, raising $10.3 million. Pebble watches can be connected to Android and iOS devices to show notifications and messages. An online app store distributed Pebble-compatible apps from many developers including ESPN, Uber, Runkeeper, and GoPro. Pebble has been succeeded by Core Devices, a company founded by Migicovsky which began manufacturing new PebbleOS devices under the Pebble name, and continuing software development on the open source PebbleOS project.
A steel-bodied variant to the original Pebble, the Pebble Steel, was announced at CES 2014 and released in February 2014. It had a thinner body, tactile metal buttons, and a Corning Gorilla Glass screen. In 2015, Pebble launched its second generation of smartwatches: the Pebble Time and Time Steel. The devices were similarly funded through Kickstarter, raising $20.3 million from over 75,000 backers and again breaking records for the site.
In December 2016, Pebble officially announced that the company would be shut down, and would no longer manufacture or continue support for any devices, nor honor any existing warranties. The company was sold to Fitbit, and many members of the Pebble staff joined the company. Support for the Pebble app store, online forum, cloud development tool, voice recognition, and voice replies ceased in June 2018, although support for some online services was restored by the unofficial "Rebble" community.
Google acquired Fitbit in 2021, which still owned the rights to Pebble's operating system, brand, and designs. In January 2025, Google announced that the source code that the operating system Pebble smartwatches use, PebbleOS, would be open-sourced with Migicovsky also announcing future devices and creating the website RePebble to market and explain the devices. In March 2025, Migicovsky announced new devices would be produced using PebbleOS by his new company, Core Devices. In July 2025, Core Devices recovered the Pebble trademark and began using the Pebble name for their watches.
In November 2025, a dispute between the Rebble organizers and Core Devices started, regarding ownership of the archive of Pebble apps, conditions of operation of the app store and general cooperation rules.
