The Pebble is the first watch built for the 21st century. It has downloadable watchfaces and useful internet connected apps. Pebble connects to the iPhone and Android smartphones using Bluetooth, alerting the user with silent vibrations to incoming calls, e-mails and messages. The Pebble is designed for so many different things such as cycling, music, running and notifications. Cyclists can use the Pebble as a bike computer, accessing the GPS on a smartphone to display speed, distance and pace data. The music control app plays, pause and skip tracks on the wrist. The pebble watch was designed based on a concept by Erc Migicovsky descibing a watch that could display messages from a smartphone. The Pebble raised $10 million for Kickstarter, making it the most successful product funded through the company. Best Buy, began selling Pebble watches in July 2013 and sold out within five days.
