Pebble is a discontinued smartwatch developed by Pebble Technology Corporation based in Palo Alto, California that shipped from 2013 to 2016. A brainchild of 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.[17] 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.

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.[4] Support for the Pebble app store, online forum, cloud development tool, voice recognition, and voice replies ceased in June 2018,[18] although support for some online services was restored by the unofficial "Rebble" community.
